RESUMO
BACKGROUND We used the 14-item Oral Health Impact Profile-14 (OHIP-14) questionnaire to evaluate the association between sociodemographic variables and oral health-related quality of life in 241 wearers of removable partial or complete dentures attending a single center in Yemen. MATERIAL AND METHODS A total of 241 partial dentures (PD) and complete dentures (CD) wearers were enrolled from the Department of Prosthodontics at the Faculty of Dentistry, Sana'a University, and the University of Science and Technology. Data were collected before the commencement of denture wearing and after 3-6 months of denture use. The questionnaire consisted of sociodemographic information and denture type, and another for the OHIP to assess oral health-related quality of life (OHRQoL), oral health impact profile scale comprises 7 subscales, each evaluating different aspects of oral health and functionality. Descriptive statistics were calculated for participants. Independent t tests were performed to compare different patient groups, focusing on PD and CD wearers. Paired-sample t tests were used to examine changes within patient groups before and after removable denture use. RESULTS Among all participants, 67.6% were male, wearers of CDs were 74.6% male, PDs were 58.3%, and was consistent for CD (71.0%) and PD (72.8%) wearers. The wearing prostheses significantly impacted the OHRQoL of patients using both PDs and CDs (P<0.01). Among CD wearers, 4 of these subscales (3-6) were statistically significant, but the handicaps subscale showed evident reductions in physical pain after treatment among PD wearers. CONCLUSIONS Wearing dentures positively affects the OHRQoL of patients, influencing various aspects of their health, including functional, physical, psychological, and social well-being.

OBJECTIVES: The purpose of this systematic review with network meta-analysis was to assess the comparative efficacy of various types of denture adhesives in complete denture patients. MATERIAL AND METHODS: A search was conducted for trials published in Scopus, PubMed, and Cochrane Central Register of Controlled Trials from inception until July 2023 (PROSPERO: CRD42023451045). A network meta-analysis was performed to assess the comparative efficacy of different denture adhesive types and ranked using the Surface Under the Cumulative Ranking (SUCRA) system. The Grading of Recommendations, Assessment, Development, and Evaluations (GRADE) approach was used to assess the level of certainty of evidence. RESULTS: Seventeen articles were included in the quantitative analysis. Cream denture adhesives significantly increased bite force in both incisal region (RR = 7.63[95%CI: 3.34, 11.91]) (P < .05) as well as premolar and molar regions (RR = 33.66[95%CI: 15.15, 52.16]). Cream adhesives significantly improved retention of dentures as assessed by the reduced number of denture dislodgments (RR = -5.35[95%CI: -9.93, -0.77]) (P = 0.022), Kapur's index of retention (maxillary denture) (RR = 0.80[95%CI: 0.18, 1.42]) (P = 0.012) and Kapur's index of retention (mandibular denture) (RR = 1.27[95%CI: 0.67, 1.87]) (P < .05). Powder adhesives significantly increased premolar and molar bite force (RR = 36.00[95%CI: 16.20, 55.79]) (P < .05) and Kapur's index of retention (mandibular denture) (RR = 1.54[95%CI: 0.58, 2.49]) (P = 0.002). None of the adhesives were statistically significant for remaining outcomes. CONCLUSIONS: Cream and powder denture adhesives are effective in enhancing the retention of mandibular dentures (Kapur's index) and bite force in the premolar/molar region in complete denture wearers (moderate level of certainty of evidence). CLINICAL RELEVANCE: Cream and powder denture adhesives are effective in improving the retention and function of complete dentures.

OBJECTIVES: To evaluate the trueness of the digital maxillary occlusal records in comparison with the conventional records for the fabrication of complete-arch implant-supported fixed prostheses. MATERIALS AND METHODS: This randomized controlled clinical trial followed the recommendations of the CONSORT statement. Twenty participants who used a mandibular interim complete-arch fixed prosthesis and conventional complete maxillary dentures were included in the study. The participants were randomized into two types of maxillary occlusal records: conventional (COR) and digital (DOR) (TRIOS; Shape A/S). After fabricating the prostheses, the distribution and number of occlusal contact points, and the time taken to obtain the maxillary occlusal record and work model were evaluated. Descriptive analysis was used to evaluate the distribution of occlusal contact points. The Wilcoxon test was employed for assessing the number of occlusal contact points, while the Mann-Whitney U test was used for the time taken to obtain the working casts and the maxillary occlusal record and occlusal adjustment times (p < 0.05). RESULTS: There was a similarity in the jaw relation recording methods regarding the distribution of occlusal contact points. There was no difference in the number of occlusal contact points between the anterior (p = 0.439) and posterior (p = 0.227) teeth. No relationship was observed between the distribution and number of occlusal contact points (COR, p = 0.288; DOR, p = 0.183). DOR required less occlusal and clinical adjustment time, on the other hand more laboratory and total workflow time than COR (p < 0.001). CONCLUSION: The DOR may be an option for obtaining the functional space necessary for the assembly of teeth in complete-arch implant-supported fixed prostheses; however, it requires more working time. CLINICAL RELEVANCE: The digital occlusal recording method can be used to assess the interocclusal space for the virtual tooth setup of a complete-arch implant-supported fixed prosthesis.

OBJECTIVES: The purpose of this scoping review was to identify different methods employed for recording the maxillomandibular relationship (MMR) for computer-aided designed and manufactured (CAD-CAM) complete dentures (CDs). MATERIALS AND METHODS: This scoping review followed the PRISMA-ScR guidelines and was developed according to Arksey and O'Malley and The Joanna Briggs Institute protocol. The methods were registered on the Open Science Framework (< osf.io/rf4xm> ). The focus question was: "What are the different techniques for recording the maxillomandibular relationship in the digital workflow used in CECDs?" Two investigators searched 3 online databases [MEDLINE (PubMed), Scopus, and Science Direct] independently. The inclusion criteria were clinical studies and reviews that assessed techniques for recording MMR using digital workflow for manufacturing of CECDs. A descriptive analysis was performed considering the study design, manufacturing system, clinical steps, and tools for the determination of MMR, and the difficulty level of procedures. RESULTS: 4779 articles were identified in the electronic search and 10 studies were included for data analysis. The review identified 4 commercially available CAD-CAM denture systems and 3 innovative methods suitable for abbreviating the number of appointments (2 to 4 visits). The trial denture is inherent to the procedure for the Baltic System and 3 innovative techniques. Three techniques (2 innovative and WholeYouNexteeth) demonstrated lower difficulty levels for performing the clinical procedures, regardless of the professional skills. CONCLUSIONS: The commercially available and innovative techniques for the recording of MMR may provide predictability of the treatment. The techniques are effective, however, rely on the learning curve and the patient's clinical condition. CLINICAL RELEVANCE: Recording of the maxillomandibular relationship is paramount for the manufacturing and functionality of complete dentures. Clinicians should be aware of the different tools and techniques described for registering the jaw relationship.

This study investigated the integration of online learning into complete denture rehabilitation (CDR) training for dental interns, highlighting its impact on their education and readiness for clinical practice. Given that CDR poses significant challenges due to its technical complexity and profound influence on patient well-being, online learning has emerged as a strategic educational tool to enhance interns' knowledge and skills. This research included the administration of a comprehensive questionnaire to 63 dental interns to assess their backgrounds, experiences with online learning, and attitudes toward its application in CDR education. The results revealed strong engagement with online learning, with a majority valuing its flexibility, accessibility, and capacity to facilitate self-paced, individualized learning. Despite the enthusiasm for online modalities, the results identified notable gaps in interns' confidence in and preparedness for performing CDR, highlighting the need for targeted improvements in online curriculum development. By emphasizing the essential role of innovative teaching methods, including virtual reality (VR), this study underscores the need for a balanced educational approach that combines traditional and digital platforms. This strategy aims to prepare future dental professionals for the complexities of modern clinical environments, ensuring that they are well equipped to meet the diverse needs of the edentulous population.

PURPOSE: To evaluate the clinical effect of three impression methods, conventional, closed-mouth, and tissue conditioner, on complete denture fabrication. METHODS: 60 subjects (edentulous with severely resorbed alveolar ridges - Atwood classification III or IV) who visited the Prosthodontic Department of Wuxi Stomatology Hospital, China, between January 2022 and June 2023, were selected for this study. The subjects were randomly divided into three groups of 20: a conventional impression group (CI group), a closed-mouth impression group (CM group), and a tissue conditioner group (TC group). Three months after denture restoration was completed, denture quality was assessed by clinicians in terms of marginal extension, retention, and stability. In addition, patients completed the oral health impact profile-edentulous (OHIP-EDENT) questionnaire to provide subjective satisfaction evaluations of the final denture restoration outcomes. RESULTS: The comprehensive denture quality evaluation results showed that the TC group had the lowest score, which was significantly lower than that of the CM (P= 0.014) and CI (P< 0.001) groups. The average score of the CM group was also significantly lower than that of the CI group (P= 0.004), indicating that tissue conditioner restoration was the most effective method. The OHIP-EDENT scores gradually decreased across the groups from CI to CM to TC (P= 0.001), indicating patients' oral health was significantly improved using tissue conditioner. CLINICAL SIGNIFICANCE: Tissue conditioner is a suitable dynamic functional impression method. It can significantly improve the effects for edentulous patients and increase their satisfaction.

STATEMENT OF PROBLEM: Computer-aided design and manufacturing (CAD/CAM) have been increasingly used to enhance the patient and clinician experiences with removable complete dentures (CDs). Yet, evidence from systematic reviews is lacking to validate the clinical significance of these digital prostheses. PURPOSE: The purpose of this systematic review was to compare CAD/CAM CDs with the traditional ones in terms of patient and clinician-reported outcomes, post-insertion adjustment visits and costs. MATERIALS AND METHODS: An electronic search of four databases [Medline (Ovid), Embase, Scopus and Cochrane CENTRAL; last update: May 2022] was performed to retrieve clinical studies comparing CAD/CAM and traditional CDs. Two independent reviewers screened the articles, extracted data (methods and outcomes) and assessed risk of bias of the included studies. The following outcomes underwent meta-analysis (random-effects model): overall patient and clinician satisfaction, oral health-related quality of life (OHRQoL), number of post-insertion adjustment visits, as well as laboratory and total costs. RESULTS: This review included 11 studies. Meta-analysis revealed that CAD/CAM CDs are comparable to the traditional CDs in terms of overall patient satisfaction and OHRQoL. Clinician-reported data depended on the manufacturing technique: whereas milled CDs performed better than traditional CDs in terms of clinician satisfaction and number of adjustments, 3D printed and traditional CDs were similar. Fabrication of CAD/CAM CDs required significantly less laboratory and overall costs than the traditional CDs. CONCLUSIONS: There is some evidence showing that CAD/CAM CDs are at least comparable to traditional CDs. Further well-designed randomized clinical trials are needed to evaluate the performance of specific CAD/CAM approaches for manufacturing CDs, however.

BACKGROUND: Denture-induced oral Lesions (DIOLs) often manifests shortly after the placement or adjustment of new or realigned dentures, frequently resulting in severe pain and discomfort. OBJECTIVES: This study aimed to classify DIOLs placing a particular emphasis on assessing the associated pain. METHODS: A prospective case study was conducted involving 126 patients who were fitted with a total of 193 dentures of various types at the Hadassah School of Dental Medicine. All patients underwent comprehensive intra-oral examinations within 1-8 weeks following denture delivery, completed symptom questionnaires and had their medical records reviewed. Key variables documented included age, gender, overall health status, denture type, and a detailed description of the DIOLs. The description encompassed factors such as lesion location, shape, colour, size, border characteristics, ulcerative appearance, membrane coverage, 3D morphology (elevated, immersed and flat) and patient-reported Verbal Pain Score (VPS) when touching the DIOLs, when wearing the denture, and when not wearing the denture. RESULTS: Notably, 25.4% of denture wearers required no adjustments, while 14.4% necessitated more than three revisions. A majority (71.8%) of DIOLs cases were associated with mandibular complete dentures, primarily situated on the alveolar ridge. The mean VPS indicated a pain intensity of 7 ± 2.1, with temporary dentures in both jaws causing the most discomfort. Implant-supported overdentures were particularly painful when placed in the mandible. Additionally, VPS scores were higher among older individuals and those with prior prosthetic experiences. A significant correlation was observed between pain intensity and presence of chronic health condition (0.036). CONCLUSIONS: This study revealed distinct characteristics of DIOLs and highlighted the multifactorial nature of pain experienced following the development of DIOLs. Insights into the influence of patient and denture characteristics on DIOLs and pain intensity can guide healthcare professionals in optimising patient comfort and satisfaction.

BACKGROUND: Differences in the effects of cream-type denture adhesives and home liners remain unclear. OBJECTIVE: This cross-sectional study aimed to clarify the differences in the oral-hygiene status and masticatory performance between participants using cream-type denture adhesives and those using home liners. METHODS: Masticatory performance with and without cream-type denture adhesives and home liners was evaluated using colour-changeable chewing gum. Oral hygiene was assessed using the tongue coating index (TCI). Propensity-score matching was performed using oral moisture, presence of palatal or mandibular protuberances, type of residual ridge, denture type (complete or partial denture), and denture retention as background factors. Wilcoxon signed-rank test was used to examine the differences in masticatory performance with and without cream-type denture adhesives and home liners and differences in masticatory performance and TCI between the cream-type denture adhesive and home-liner groups. RESULTS: This study included 38 and 40 cream-type adhesive and home-liner users, respectively, and 17 pairs were obtained after propensity-score matching. The Wilcoxon signed-rank tests showed that masticatory performance was significantly different with and without the use of home liners, and higher values were obtained with the use of home-liners. However, the cream-type denture adhesive and home-liner groups showed no significant differences in terms of the change in masticatory performance with the use of them. Furthermore, Wilcoxon signed-rank tests showed that TCI values were significantly high in the cream-type adhesive group. CONCLUSION: The findings in this study suggest that home liners improve masticatory performance and that participants regularly using cream-type denture adhesives have poorer oral hygiene.

PURPOSE: To investigate the influence of different denture-bearing conditions on the masticatory function and patient-reported outcome measures (PROMs) of complete denture wearers. METHODS: Sixty edentulous patients were selected and allocated into two groups according to the American College of Prosthodontics' (ACP) classification: non-atrophic (NAT) (Classes I and II) (n = 24) and atrophic (AT) (Classes III and IV) (n = 36). All patients received new complete dentures (CDs). The objective variables (masticatory performance and swallowing threshold) were assessed as well as the PROMs (oral health-related quality of life (OHIP-EDENT), patient satisfaction) and quality of the prosthesis, at baseline (using the old CD) and after 4 months new prostheses use. Data were analyzed by Mann-Whitney test followed by the Generalized Equations Estimation (GEE), linear regression and Chi-square test. RESULTS: Higher masticatory performance was observed in the NAT group (p < .05) for both time points, baseline and after 4 months. However, compared to baseline, both groups showed significant masticatory improvement after 4 months (p < .05). Satisfaction and overall quality of life improved after 4 months with no difference between groups (p > .05). Regarding the quality of the CD, baseline results were significantly (p < .05) lower in the AT group, but after 4 months, no significant differences were found between groups and in intragroup analysis (p > .05). CONCLUSIONS: The denture-bearing conditions seems to impact masticatory function, but the PROMs are barely affected.

BACKGROUND: Wearing complete denture in one or both arches can impact enjoyment of eating and affect quality of life compared with being dentate. Clinicians focus on issuing technically sound dentures but ignore the impact of wearing dentures on the eating-related quality of life which affects the success of treatment. OBJECTIVES: The aim of this research was to qualitatively explore ERQoL in Australian adults wearing complete dentures using a validated questionnaire and through focus groups. METHODS: Complete denture wearers (n = 44) were recruited from dental clinics and invited to complete the self-administered Emotional and Social Issues Related to Eating questionnaire. Responses were categorised under the six questionnaire domains. A subsample of 20 participants who completed the questionnaire were invited to participate in focus groups to identify emerging themes. RESULTS: Twenty-three participants (52.3%) completed the questionnaire. Most participants expressed a decline in enjoyment of eating due to reduced ability to eat, longer chewing times and the need to frequently clean dentures while eating. Focus groups (n = 2 × 4 participants) indicated educational materials on eating with dentures would increase recognition of eating problems with dentures and reduce trial and error approaches to dealing with these. CONCLUSION: ERQoL is adversely affected by wearing complete dentures due to functional limitations, restricted food choices and adaptive eating behaviours. Patient support for eating well with a complete denture/s wearers is required.

OBJECTIVE: Digitally-designed removable complete dentures are typically composed of a resin denture base without a metal framework. However, metal denture bases are preferable as resin bases are more susceptible to fracture. Therefore, this article introduces a unique technique that integrates computer-aided design (CAD) and conventional resin processing for the fabrication of removable complete dentures with a metal framework. CLINICAL CONSIDERATIONS: A maxillary complete denture with a metal base and a mandibular implant-retained overdenture reinforced with a metal framework were fabricated. The dentures were designed using CAD software and a tooth library. The denture bases were milled from wax disks, and artificial teeth were placed to complete the wax dentures. The metal frameworks were also designed using CAD software and produced via casting of printed resin patterns. Finally, conventional denture processing techniques were applied to obtain dentures with metal frameworks. CONCLUSIONS: A digitally designed, removable complete denture with a metal base can be successfully fabricated using the described technique, which merges digital design and conventional methods. This article demonstrates the feasibility and potential advantages of this innovative approach in denture fabrication. CLINICAL SIGNIFICANCE: The presented technique provides the following advantages: digital design features, precise space above implant overdenture attachments for a metal framework, convenience of esthetic evaluation with printed trial dentures, long-term data storage and duplication, reliable bond between the artificial teeth and denture base, and enhanced strength of the removable complete denture due to the metal reinforcement.

OBJECTIVE: This article highlights a CAD/CAM complete-mouth rehabilitation in an 82-year-old patient by means of a complete maxillary prosthesis and mandibular implant- and tooth-supported fixed restorations made from multilayered zirconia. CLINICAL CONSIDERATIONS: Comprehensive complete-mouth rehabilitations in elderly patients with adaptation of the occlusal vertical dimension (OVD) often present particular challenges. This applies especially when exacting functional and esthetic requirements are to be met and the treatment should not cause the patient too much effort, still ensuring the highest level of quality and efficiency and a low intervention rate. CONCLUSION: The digital approach used for the present patient allowed for an efficient treatment procedure, facilitated virtual evaluations using a face-scan, and enhanced the predictability of the prosthodontic outcome. The approach enabled some steps required in the conventional protocol to be omitted, resulting in a straightforward clinical treatment with minimal strain on the patient. CLINICAL SIGNIFICANCE: Because of the comprehensive recording of extraoral and intraoral data, for example with a facial scanner, it was possible to transfer a digital replica of the patient to the dental laboratory technician. With this protocol, many steps can be performed in the absence of the real patient.

STATEMENT OF PROBLEM: Computer-aided design and computer-aided manufacturing (CAD-CAM) removable dentures have become popular. However, evaluations of the effect of denture base-tooth offset (DTO) values on the trueness of artificial teeth are lacking. PURPOSE: The purpose of this in vitro study was to digitally measure the trueness of the artificial teeth of CAD-CAM dentures fabricated with additive manufacturing using different DTO values and to determine the most accurate DTO value. MATERIAL AND METHODS: Seven study groups were formulated based on different DTO values, and 6 maxillary complete dentures were assigned to each group (n=42). A design software program was used to export the monoblock denture as control, the artificial teeth, and 7 different designs of denture bases with DTO values of 0.00, 0.01, 0.03, 0.05, 0.10, 0.15, and 0.20 mm. Denture bases were printed in denture base resin (Denture base RP; formlabs), artificial teeth were printed in tooth-shade resin (Denture teeth A2; formlabs), and both were then assembled and polymerized together. The dentures were scanned (InEos X5; Dentsply Sirona), scan data were imported in a measuring software program (GOM Inspect; GOM GmbH), and registration using local best fit was performed to align data. Color-coded maps for the surface comparison of each denture with the control denture scan were generated. Fitting center points were constructed for each artificial tooth, which were compared with their corresponding points on the data of the control scan. Multiple pairwise comparisons were performed after 1-way ANOVA to quantify and statistically evaluate the deviation values (α=.05). RESULTS: The 0.10-mm DTO group showed the lowest values when comparing artificial tooth deviations both individually and as types. On comparing the average deviations, statistically significant differences were identified among the 7 groups (P<.001). A nonstatistically significant difference was identified when the 0.10- and 0.05-mm DTO groups were compared. Lower deviation values were found in the premolars compared with the molars, in the incisors compared with the canines, and in posterior artificial teeth compared with anterior teeth. CONCLUSIONS: The 0.10-mm DTO value showed the highest trueness for the artificial teeth compared with the other DTO values tested in this study. The 0.05-mm DTO value is an alternative to the 0.10-mm DTO value for CAD-CAM dentures constructed by additive manufacturing. Anterior teeth of a CAD-CAM denture showed higher deviation values compared with posterior teeth.

STATEMENT OF PROBLEM: The demand to streamline workflow while increasing patient comfort and satisfaction in the manufacturing of removable complete dentures (CDs) is growing, and computer-aided design and computer-aided manufacturing (CAD-CAM) technology has gained prominence. However, a systematic review and meta-analysis of the clinical performance and patient-related outcome measures (PROMs) of digitally fabricated complete dentures is lacking. PURPOSE: The purpose of this systematic review and meta-analysis was to determine whether digitally fabricated CDs improve the clinical performance and PROMs compared with conventionally fabricated CDs. MATERIAL AND METHODS: This systematic review followed the Preferred Reporting Items for Systematic Reviews and Meta-Analyses and was registered at the International Prospective Register of Systematic Reviews (CRD42023433909). This review aimed to address the question "Do digitally fabricated CDs improve clinical performance and PROMs compared with conventional CDs?" Two independent authors conducted electronic searches up to September 2023. Denture base retention and patient satisfaction were analyzed through the continuous outcome evaluated by mean difference and standard deviation, with 95% confidence intervals. The risk of bias in each study was assessed using the Risk of Bias In Non-randomized Studies of Interventions and the Risk of Bias based on the Cochrane risk of bias tool for randomized trials. The certainty of evidence was assessed using Grading of Recommendations, Assessment, Development and Evaluation. RESULTS: A total of 1505 articles were found during the search, and 16 were included in this review. The main outcomes were grouped into clinical performance (retention, adaptation or fit, clinician's denture quality assessment, masticatory efficiency, and occlusal force) and PROMs (patient satisfaction, oral health related quality of life, final choice, and willingness-to-pay). In terms of denture base retention, between conventional CDs and printed CDs analyses, conventional CDs exhibited better retention (P=.02), but no significant difference was found between the conventional CDs and milled CDs (P=.20). In terms of patient satisfaction, no statistically significant difference was found between the manufacturing methods of digitally fabricated CDs (printed CD, P=.55; milled CD, P=.08). CONCLUSIONS: Digitally fabricated CDs showed similar or better clinical performance than conventional CDs, and different types of digital manufacturing processes for complete dentures did not influence PROMs.

STATEMENT OF PROBLEM: Technological advances in digital acquisition tools have increased the scope of intraoral scanners (IOSs), including scanning a removable complete denture (RCD) to replicate it. However, studies assessing the accuracy of IOSs for replicating a maxillary or mandibular RCD are lacking. PURPOSE: The purpose of this in vitro study was to evaluate the accuracy (trueness and precision) of 3 IOSs while replicating a maxillary and mandibular RCD. MATERIAL AND METHODS: One maxillary and 1 mandibular RCD were scanned with a desktop scanner (D2000) to obtain the reference model. Two operators scanned each RCD 5 times with 3 different IOSs (TRIOS 4, Primescan, and IS3800), following a predefined acquisition protocol. The 60 study models obtained were compared with the reference model using the Geomagic software program. For each comparison, the mean and standard deviation of discrepancy were calculated. Distances were measured on both the reference and the study model, and differences were calculated to assess whether sagittal or transverse deformations were present. The tolerance percentage of the volume of the digital model compared with the volume of the reference model was determined (difference tolerance was set at 0.1 mm). A univariate analysis of variance followed by a post hoc analysis using the Student-Newman-Keuls (α=.05) test was performed to determine the truest and the most precise IOS. RESULTS: The TRIOS 4 and Primescan IOSs had comparable trueness, with mean dimensional variations of 47 ±27 µm and 57 ±8 µm respectively compared with the reference model. The IS3800 had a lower trueness (98 ±35 µm). Primescan was significantly more precise with a mean standard deviation of 64 ±15 µm (P<.05). The TRIOS 4 (141 ±48 µm) and IS3800 (129 ±24 µm) had comparable precision. Primescan showed the least sagittal and transverse deformation. CONCLUSIONS: This study determined that an RCD can be replicated using an IOS, although all IOSs did not have equal accuracy. An in vivo study needs to assess whether this procedure is clinically acceptable.

OBJECTIVE: To describe the clinical procedures of complete denture set fabrication in three appointments. BACKGROUND: Simplified approaches have proven not to be inferior to conventional ones in terms of quality, patient satisfaction and masticatory ability. MATERIALS AND METHODS: The patient was a 77-year-old edentulous adult with mobility impairment seeking dental rehabilitation in a small number of appointments due to commuting difficulties. RESULTS: A set of complete dentures was delivered within three appointments. The second appointment was dedicated to set-up trial due to the patient's aesthetic demands. CONCLUSION: Under certain circumstances and after a thorough study of each case, dental clinicians may propose the fabrication of complete dentures in a three-appointment protocol incorporating a set-up trial session.

OBJECTIVE: Examine the literature on the experiences of living with removable dentures (complete or partial) to identify any gaps and provide a map for future research. BACKGROUND: Increasing proportions of society are living partially dentate with some form of restoration, including removable dentures. Previous studies have reported on the location, materials and usage of these prostheses, along with effects on oral-health-related quality of life (OHRQoL). However, less is known about experiences with removable dentures from a patient-centred perspective. METHODS: A scoping review of the qualitative literature was undertaken using the framework of Arksey and O'Malley, updated by Levac et al. Literature searches were carried out using Medline and Web of Science. Papers were screened by title and abstract using inclusion and exclusion criteria. Remaining papers were read in full and excluded if they did not meet the required criteria. Nine papers were included in the final review. FINDINGS: Key themes from these papers were: impact of tooth loss and living without teeth, and its impacts in relation to social position, appearance, confidence and function (chewing and speaking); social norms and tooth loss, including attitudes to tooth retention and treatment costs, and changes in intergenerational norms towards dentures; expectations of treatment, including patients being more involved in decision making, viewing the denture as a "gift" and dentures helping to achieve "an ideal"; living with a removable denture (complete or partial), including patient preparedness for a denture, adaptation and impacts on activities and participation; and the dentist-patient relationship, including issues with information and communication, and differing priorities between patients and dentists. CONCLUSION: Little qualitative research exists on experiences of living with a removable denture. Existing literature demonstrates the importance of dispersed activities in differing social, spatial and temporal contexts when wearing removable dentures. Focusing on processes of positive adaptation to dentures and OHRQoL, rather than deficits, is also required to fully understand patients' experiences. Additionally, more complex technological advances may not always be in the best interest of every patient.

BACKGROUND: The establishment of good facial esthetics is one of the main objectives of complete denture construction. Unfortunately, it may be the caused issue for patients having a prominent premaxilla due to excessive lip support by the labial flange of the maxillary denture. Open-face dentures (OFD) may suggest suitable prosthetic management for these patients. However, clinical evidence regarding the efficiency of OFD is scarce. METHODS: A total of 38 completely edentulous participants having prominent premaxilla and skeletal class I Angle's classification were enrolled in this study. Each participant received a mandibular complete denture and 2 opposing maxillary dentures; conventional (CD) and open-face (OFD). On the day of denture insertion, the participants were divided into 2 groups; CD-OFD and OFD-CD where CD-OFD group was instructed to use the mandibular denture and the maxillary CD for 3 months and then to use the maxillary OFD for another 3 months after a wash-out period of 2 weeks. While group OFD-CD was instructed to use the mandibular denture and the maxillary OFD for 3 months then to use the maxillary CD for another 3 months after a wash-out period of 2 weeks. The dislodging force of the maxillary dentures was evaluated using the universal testing machine and the patient perception of retention, esthetics, and comfort was evaluated using the Visual Analogue Scale (VAS). Evaluation was carried out 1 day, 1 month, and 3 months after denture insertion. The Student t-test was used to compare the 2 maxillary dentures and the intervals for each denture were compared by using the ANOVA test with repeated measures followed by a Post Hoc test (adjusted Bonferroni) for pairwise comparison. RESULTS: The significance of the obtained results was judged at the 5% level (P value). The dislodging force and patient perception of retention did not show significant differences between the 2 dentures, while the perception of esthetics showed significant differences throughout the follow-up period. Perception of comfort showed an insignificant difference only at the 3-month interval. CONCLUSIONS: Open-face maxillary dentures can be a suitable alternative for patients with prominent premaxilla to achieve satisfactory retention, aesthetics, and comfort.

BACKGROUND: Edentulism remains a major disability worldwide, especially among the elderly population, although the prevalence of complete edentulism has declined over the last decades. In Uganda, the prevalence of edentulism in people aged 20 years and above is 1.8%. The therapy for edentulous patients can be realized through the use of conventional removable complete dentures, implant-supported prostheses, and computer-aided design and computer-aided manufacturing (CADCAM), however, the provision of removable complete dentures continues to be the predominant rehabilitation for edentulous patients. However, no published study has explored the lived experiences with removable complete dentures among the Ugandan population. The aim of the present study was to explore patients' lived experiences on the usage of removable complete dentures among Ugandan edentulous patients attending Makerere University Dental Hospital. METHODS: This was a qualitative study approach using purposive sampling. Fifteen (15) respondents were selected across social demographics. Interviews were recorded and transcribed and themes were generated to draw a deeper meaning to the usage of removable complete dentures. A qualitative statistical package, Atlas Ti software was used to generate themes from the interviews followed by an interpretation of the generated data and the results were presented as text and in a table. RESULTS: The reported key positive experiences due to removable complete denture rehabilitation were the improvement in speech, eating ability, regaining good facial appearance, better oral hygiene management, self-esteem and confidence to smile in public, and a feeling of completeness. However, respondents complained of pain and discomfort due to the looseness of dentures, inability to eat certain foods, and regular cleaning of dentures. The respondents did not go through proper informed consent processes before getting removable complete dentures. CONCLUSION: The study found that patients were satisfied with their removable complete dentures rehabilitation due to the positive experiences registered, such as the ability to eat and talk well, and restoration of self-esteem, all of which improved their quality of life. However, they experience pain and discomfort due to the looseness of dentures.
