RESUMEN

In everyday practice, surgeons have to deal with bone atrophy. These rehabilitations are even more complex in the posterior mandible, and it is still unclear in the literature which fixed rehabilitation option is best. The purpose of this article was to help oral surgeons to choose the proper and updated treatment for their atrophic patients. Posterior mandible bone atrophies were divided into four main groups depending on the bone height measured above the inferior alveolar nerve: (1) ≤ 4 mm; (2) > 4 mm ≤ 5 mm; (3) > 5 mm ≤ 6 mm; (4) > 6 mm < 7 mm. Different approaches were proposed for each group, considering patient expectations. If ≤ 4 mm of bone height was available, guided bone regeneration was used as the adequate approach. For bone heights > 4 mm and ≤ 6 mm, the "sandwich" technique and/or short implants were used, depending on esthetics. In cases with > 6 mm and < 7 mm above the mandibular canal, short implants might be the proper option. The authors' clinical experience and the literature were considered in order to suggest a possible correct treatment decision based on the residual bone height in the posterior mandible.

RESUMEN

OBJECTIVES: To introduce an esthetic index for assessing the outcomes of peri-implant soft tissue dehiscence/deficiency (PSTD) coverage and test its within- and between-reviewer reliability. MATERIALS AND METHODS: Photographs of 51 single PSTDs at baseline and after treatment were provided to four periodontists from three centers. The examiners were asked to rate each case at two timepoints with the Implant soft tissue Dehiscence/deficiency coverage Esthetic Score (IDES) that involved the evaluation of the post-treatment level of the soft tissue margin, peri-implant papillae height, mucosa color, and mucosa appearance (summing up to a total score of 10). Variance components analysis was conducted using multilevel regression fit in a Bayesian framework for obtaining uncertainty intervals for fractional variance contributions and intraclass correlation values (ICC) of the IDES, and for each of its four clinical variables. RESULTS: Regression models showed reproducible esthetic evaluation among the examiners (inter-reliability) and negligible intra-reviewer variability (assessment of the same case at different timepoints). The ICC for the variability in the assessment of the overall IDES was 0.86, and for the individual components ranged from 0.78 to 0.87. Additionally, there was a strong similarity between the raters' IDES values, and their subjective esthetic response, by the same raters. CONCLUSION: The IDES showed persistent judgment among the 4 reviewers, and only a slight intra-reviewer variability across timepoints. Within its limitations, this study suggests that the proposed novel score can be a reliable tool for evaluating the esthetic outcomes of PSTD coverage, which can aid in standardization of esthetic assessments following the treatment of a PSTD.

RESUMEN

OBJECTIVES: The Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) is a new coronavirus detected in China at the end of 2019. Because SARS-CoV-2 is highly infectious due to contamination in the air, there is a high risk of infection in the dental environment which is represents a serious problem for professionals and students (dentistry and dental hygiene). In Italy, since February 23, 2020, the government has suspended all teaching activities of schools and universities. METHODS: An anonymous questionnaire was administered to the students of the degree courses in Dental Hygiene of the Emilia Romagna Region, one of the most affected regions in Italy. The survey was intended to highlight the practical and emotional consequences of the emergency of COVID-19 on educational activities and in the training of students. RESULTS: The survey was sent to the 150 students enrolled in the universities of Bologna, Ferrara and Modena and Reggio Emilia; 141 of them completed it (94%). Since the start of the COVID-19 pandemic, several surveys have been proposed to measure the impact of this emergency situation on dental professionals; at present, however, there are still no assessments for dental hygiene degree courses, in particular aimed at assessing the psychological impact on students. CONCLUSIONS: Students consider the dental hygienist as a risky profession, while the risk taken by patients is considered as low. Given the concern reported the students, it would be useful to address the issue of proper assessment of risk during the university training of dental hygienists.

RESUMEN

When it comes to complete root coverage of exposed root surfaces, several limiting factors have been suggested. Although tooth malposition and papillae dimension are capable of influencing root coverage, they have not received sufficient emphasis in the literature. Therefore, the aim of the present commentary is to discuss the impact of tooth malposition and papillae dimension on root-coverage outcomes. This commentary combines evidence from the literature with the authors' experience. Limited evidence is available in the literature regarding the influence of tooth malposition on root-coverage outcomes. Severe buccal displacement and tooth extrusion and/or rotation may limit the amount of achievable root coverage, and the cementoenamel junction should no longer be considered the landmark for root coverage in these cases. The relationship between papillae dimension and root coverage has been tested in different clinical conditions and by applying different root-coverage approaches, thereby resulting in contradictory outcomes. The clinical experience of the authors suggests that having wider papillae is advantageous for coronally advanced flap and tunnel flap preparations and connective tissue graft stabilization. Although scientific evidence and the authors' clinical experience suggest that papillae dimension can play a major role in determining the surgical management of soft tissues and the amount of achievable root coverage, further studies are necessary to evaluate to which extent papillae dimensions contribute to treatment outcomes.

RESUMEN

This case report describes the rehabilitation of an extremely atrophic posterior mandible using 4-mm ultrashort implants and reports clinical and radiographic outcomes 7 years after loading. The patient refused to undergo any other treatment, from the removable prosthesis to the reconstructive surgery, and asked for a fixed, minimally invasive solution in the shortest possible time. The residual bone height above the alveolar nerve was an average of about 5 mm, so it was decided to treat the patient with four 4-mm ultrashort implants. Within the limitations of this case report, this procedure appears successful at 7 years after loading in this specific case and could reduce invasiveness, rehabilitative times, and costs. However, longer follow-ups on a large number of patients coming from randomized controlled clinical trials are necessary before making more reliable recommendations.

RESUMEN

The new classification of periodontal diseases recognizes the key role of the interdental clinical attachment for defining the periodontal status and the extent of disease severity. Regenerating interdental clinical attachment not only improves the prognosis of the tooth, but it also lessens the severity of the disease condition. This manuscript provides a state-of-the-art review on surgical reconstructive approaches for treating papillary deficiency associated with soft and hard tissue interproximal defects. Combination therapy of papilla preservation, connective tissue grafting, and coronally advanced flaps may result in regeneration of the intrabony defect coupled with root coverage. Future research highlighted in this review may have the potential especially in combination approaches to repair challenging interproximal soft and hard tissue deficiencies.

RESUMEN

STATEMENT OF PROBLEM: The effect of prophylactic polishing pastes on composite resin materials has been extensively investigated, but little is known about their effect on ceramic materials. PURPOSE: The purpose of this in vitro study was to evaluate the effect of prophylactic polishing pastes on the 2D and 3D roughness, translucency, and gloss of different ceramic materials. MATERIAL AND METHODS: A total of 120 flat specimens (thickness: 2 mm) obtained from computer-aided design and computer-aided manufacturing (CAD-CAM) blocks of leucite glass-ceramic (Empress CAD), lithium disilicate glass-ceramic (e.max CAD), and zirconia (Zenostar MT) were glazed and sintered. Forty specimens from each material were then divided into 4 groups and polished with Cleanic fine, Nupro fine, or Proxyt fine pastes, leaving the control group untreated. The specimens were polished for 2 minutes with a prophylaxis cup mounted on a handpiece, applying a constant load of 3.9 N at 2000 rpm. Surface roughness was measured by using a contact profilometer and a 3D optical profilometer. The translucency parameter and gloss value were calculated by using a spectrophotometer and a glossmeter. One specimen per group was observed by scanning electron microscopy at ×200 magnification. Differences in means were compared by using 2-way ANOVA followed by the Tukey honestly significant difference (HSD) test (α=.05). RESULTS: The 2D roughness of Empress was lower than that of e.max (P<.05) and was increased by using Cleanic fine and Nupro fine pastes (P<.05). The translucency parameter values of Empress and Zenostar decreased with the use of Nupro fine paste (P<.05). Zenostar showed the lowest translucency (P<.05). The effect of prophylactic polishing pastes on gloss was minimal (P>.05). The gloss of Empress was higher than that of Zenostar and e.max (P<.05). The Pearson correlation showed that gloss and surface roughness were correlated (P<.001). CONCLUSIONS: Polishing procedures can alter the surface of a ceramic restoration.

RESUMEN

BACKGROUND: Patient-reported outcomes have received a great deal of interest in periodontal plastic procedures. However, their evaluation has mainly been short-term. Thus, the aim of this study was to evaluate the impact of soft tissue grafting procedures conducted over a decade ago on the willingness of a patients to undergo the surgery again. METHODS: Subjects that received an autogenous soft tissue graft over 10 years ago were screened and invited for a survey. Their response was only analyzed if they were able to correctly identify the sites of the surgical procedures. Dichotomous questions and visual analogue scales (VASs) were used to assess self-reported pain, willingness to retreat and satisfaction. RESULTS: Fifty-two patients were included in the analyses. Higher pain was reported for mandibular sites, and treated areas including ≥ 3 teeth (P < 0.01). Willingness to retreatment was 84.6% and it was negatively associated with self-reported pain measures, the arch location (mandible), and number of treated sites (≥3 teeth) (P < 0.01). Mean satisfaction rate was 86.9 ± 13.65 (VAS) and showed a positive correlation with willingness to retreat (P < 0.01). Having a complete root coverage at the recall visit was also significantly associated with higher patient satisfaction scores (P < 0.01). CONCLUSIONS: Patient experience of previous autogenous soft tissue grafting has an influence on their decision to undergo future treatment. Willingness to retreat was negatively affected by mandibular sites, larger treated areas and the perceived pain, while presenting with complete root coverage was significantly associated with patient satisfaction.

RESUMEN

BACKGROUND: The long-term outcomes of acellular dermal matrix (ADM) for the treatment of isolated gingival recessions has not yet been evaluated. Thus, the aim of this study was to observe the root coverage outcomes of coronally advanced flap with ADM over time, and compare them with their adjacent untreated sites. METHODS: Twelve patients (from 20) were available at the 9-year recall. Clinical parameters (recession depth, mean root coverage [mRC], keratinized tissue width [KTW], and gingival thickness) were evaluated and compared with the 1-year results, and the ADM-adjacent untreated sites (on mesial and distal) via mixed-modeling regression analyses. RESULTS: From 1 to 9 years, the ADM-treated isolated recessions showed a relapse from 77% to 62% mRC (P <0.05). A similar pattern toward apical shift of the gingival margin was noticed for the ADM-adjacent untreated sites without baseline recession. However, ADM-adjacent untreated sites which had presented with recession at baseline but were not treated showed a significantly more apical shift of the gingival margin (almost two-fold). A significant increase in KTW was noted for all sites. Baseline KTW ≥2 mm was a significant predictor for the stability of the gingival margin at the ADM-treated, and the ADM-adjacent sites with baseline recession. CONCLUSIONS: ADM-treated sites displayed recession relapse from 1 to 9 years. The untreated adjacent sites with a recession at baseline, showed a higher apical displacement of the gingival margin compared with the ADM-treated sites, and ADM-adjacent sites without a recession at baseline.

RESUMEN

OBJECTIVE: To test the safety of a new volume-stable collagen matrix (VCMX) in combination with coronally advanced flap (CAF) for the treatment of single gingival recession. MATERIAL AND METHODS: Ten patients were treated for single RT1 gingival recession. Complete and mean root coverage, gingival thickness and keratinized tissue height, patient-reported outcome measures (PROMs), and safety were assessed up to 180 days. Descriptive statistics were used to analyze the clinical parameters. RESULTS: VCMX resulted to be safe with no serious adverse events in all patients. At 6 months, root coverage was 96.7% with 90% of defects exhibiting complete coverage. There was an increase in mean width of keratinized tissue (KT) (0.4 ± 0.8 mm) and in gingival thickness (GT) (0.4 ± 0.34 mm); however, the difference was not statistically significant compared to baseline parameters. Pain perception and pain-killer consumption were low and decreasing further at 7 days. Esthetic satisfaction for both patients and experts revealed excellent scores. CONCLUSIONS: VCMX is a safe and well-tolerated device for the treatment of single gingival recessions. In combination with CAF, it resulted in a high performance in terms of mean and complete root coverage, KT width, and GT increase. VCMX may reduce patient discomfort and post-operative morbidity. CLINICAL RELEVANCE: VCMX is a safe and stable substitute for the treatment of gingival recession in conjunction with coronally advanced technique.

RESUMEN

BACKGROUND: The periodontal phenotype consists of the bone morphotype, the keratinized tissue (KT), and gingival thickness (GT). The latter two components, overlying the bone, constitute the gingival phenotype. Several techniques have been proposed for enhancing or augmenting KT or GT. However, how phenotype modification therapy (PMT) affects periodontal health and whether the obtained outcomes are maintained over time have not been elucidated. The aim of the present review was to summarize the available evidence in regard to the utilized approaches for gingival PMT and assess their comparative efficacy in augmenting KT, GT and in improving periodontal health using autogenous, allogenic, and xenogeneic grafting approaches. METHODS: A detailed systematic search was performed to identify eligible randomized clinical trials (RCTs) reporting on the changes in GT and KT (primary outcomes). The selected articles were segregated into the type of approach based on having performed a root coverage, or non-root coverage procedure. A network meta-analysis (NMA) was conducted for each approach to assess and compare the outcomes among different treatment arms for the primary outcomes. RESULTS: A total of 105 eligible RCTs were included. 95 pertaining to root coverage (3,539 treated gingival recessions [GRs]), and 10 for non-root coverage procedures (699 total treated sites). The analysis on root coverage procedures showed that all investigated techniques (the acellular dermal matrix [ADM], collagen matrix [CM], connective tissue graft [CTG]) are able to significantly increase the GT, compared with treatment with flap alone. However, KT was only significantly increased with the use of CTG or ADM. Early post-treatment GT was found to inversely predict future GR. For non-root coverage procedures, only the changes in KT could be analyzed; all investigated treatment groups (ADM, CM, free gingival graft [FGG], living cellular construct [LCC], in combination with an apically positioned flap [APF]), resulted in significantly more KT than treatment with APF alone. Additionally, the augmented GT was shown to be sustained, and KT displayed an incremental increase over time. CONCLUSIONS: Within its limitations, it was observed that any graft material was able to significantly enhance GT, while KT in root coverage procedures was significantly enhanced with CTG and ADM, and in non-root coverage procedures, with ADM, CM, FGG, and LCC compared with APF alone. The autogenous soft tissue graft (CTG/FGG) proved to be superior in all comparisons for both outcomes of GT and KT.

RESUMEN

Peri-implant soft tissues play a role of paramount importance, not only on the esthetic appearance, but also on the maintenance and long-term stability of implants. The present report presents the conclusions from the Consensus Conference of the South European North African Middle Eastern Implantology & Modern Dentistry Association (SENAME) (4-6 November 2016, Cairo, Egypt). The conference focused on the topic of the soft tissue around dental implants, and in particular, on the influence of implant configurations on the marginal soft tissues, soft tissue alterations after immediate, early or delayed implant placement and immediate loading, the long-term outcomes of soft tissue stability around dental implants, and soft tissue augmentation around dental implants. Thirty world experts in this field were invited to take part in this two-day event; however, only 29 experts were in the final consensus voting process.

RESUMEN

This case report aimed to describe a soft tissue approach to restore a buccal soft tissue dehiscence (BSTD) combined with the loss of peri-implant papillae and loss of periodontal attachment on the adjacent teeth. The first step of the proposed approach was the removal of the crown and abutment to leave the interproximal soft tissue to fill the space previously occupied by the crown. After 3 months, during which time the patient was wearing a provisional restoration (a temporary Maryland bridge), the implant site was treated as an edentulous area with a soft tissue augmentation procedure: the most substantial modification with respect to the original connective tissue platform technique was the use of the wide mesial and distal papillae of the implant, once de-epithelialized on the occlusal surface, as a "partial" connective platform to suture the connective grafts and submerge the implant. At the 4-month reevaluation visit, a minor soft tissue defect remained in both apico-coronal and buccolingual dimensions, and thus a second surgery was performed to obtain further soft tissue augmentation. A flapless punch procedure was used to expose the implant head, and after conditioning the augmented peri-implant soft tissue with a new provisional crown, the definitive restoration was delivered. Complete coverage of the BSTD was achieved, and both papillae entirely filled the interproximal spaces. The results were well maintained up to the 5-year follow-up visit.

RESUMEN

This state-of-the-art review presents the latest evidence and the current status of autogenous soft tissue grafting for soft tissue augmentation and recession coverage at teeth and dental implant sites. The indications and predictability of the free gingival graft and connective tissue graft (CTG) techniques are highlighted, together with their expected clinical and esthetic outcomes. CTGs can be harvested from the maxillary tuberosity or from palate with different approaches that can have an impact on graft quality and patient morbidity. The influence of CTGs on soft tissue thickness and keratinized tissue width are also discussed.

RESUMEN

The cultivation of human living cells into scaffolding matrices has progressively gained popularity in the field of periodontal wound healing and regeneration. Living cellular constructs based on fibroblasts, keratinocytes alone or in combination have been developed and used as alternatives to autogenous soft tissue grafts in keratinized tissue augmentation and in root coverage procedures. Their promising advantages include reduced patient morbidity, unlimited graft availability, and comparable esthetics. This manuscript reviews soft tissue augmentation and root coverage procedures using bioengineered living cellular therapy and highlights their expected clinical, esthetic, and patient-related outcomes.

RESUMEN

The present article focuses on the properties and indications of scaffold-based extracellular matrix (ECM) technologies as alternatives to autogenous soft tissue grafts for periodontal and peri-implant plastic surgical reconstruction. The different processing methods for the creation of cell-free constructs resulting in preservation of the extracellular matrices influence the characteristics and behavior of scaffolding biomaterials. The aim of this review is to discuss the properties, clinical application, and limitations of ECM-based scaffold technologies in periodontal and peri-implant soft tissue augmentation when used as alternatives to autogenous soft tissue grafts.

RESUMEN

This manuscript provides a state-of-the-art review on the efficacy of biologics in root coverage procedures, including enamel matrix derivative, platelet-derived growth factor, platelet concentrates, and fibroblast-growth factor-2. The mechanism of action and the rationale for using biologics in periodontal plastic surgery, as well as their anticipated benefits when compared with conventional approaches are discussed. Although the clinical significance is still under investigation, preclinical data and histologic evidence demonstrate that biologic-based techniques are able to promote periodontal regeneration coupled with the provision of tooth root coverage.

RESUMEN

Soft tissue augmentation procedures are crucial to obtain a successful outcome in implant therapy. The aim of this case series was to describe the 1-year clinical outcomes of a porcine-derived acellular dermal matrix for buccal mucosal thickness augmentation at osseointegrated single implants with facial peri-implant soft tissue deficiencies. Ten patients were included and treated with a prosthetic and surgical approach that combined a coronally advanced flap and a dermal matrix. Results showed the possibility to obtain an increase in buccal soft tissue thickness of 1.2 ± 0.18 mm at single implant sites in the esthetic area.

RESUMEN

BACKGROUND: Tooth location has been shown to play a significant role on root coverage outcomes. However, whether this has an impact on the outcomes of coronally advanced flap (CAF) for treating multiple adjacent gingival recessions (MAGRs) remains to be determined. The aim of this study was to investigate the impact of tooth location, flap design, and flap extension on the outcomes of MAGRs following CAF with or without a connective tissue graft (CTG). METHODS: A re-analysis of six previously published clinical trials evaluating the outcomes of CAF in the treatment of MAGRs was performed using mixed regression and logistics to assess the influence of potentially influential factors on the treatment outcomes. RESULTS: Six hundred and nine MAGRs in 166 patients were evaluated. The anterior maxilla (second sextant) was associated to the highest mean root coverage (mRC) and complete root coverage (CRC) outcome (P < 0.05). In addition, the maxillary teeth showed significantly greater mRC and CRC than teeth in the mandible (with the lower anterior [fifth sextant] showing the lowest outcomes) (P < 0.05). A higher mRC was observed for the anterior teeth compared with posterior dentition (P < 0.05). While CAF + CTG achieved better results than CAF alone, no differences were found when the flap was performed with or without vertical releasing incisions (P > 0.05). Lastly, teeth in the distal part of the flap showed lower mRC and CRC than teeth in the central or mesial position (P < 0.05). CONCLUSIONS: Tooth location was found to play a key role in determining the amount of root coverage achievable, with maxillary canines and incisors being associated with the highest outcomes compared with other sextants. Maxillary MAGRs showed greater mRC and CRC than mandibular MAGRs.

RESUMEN

BACKGROUND: The incidence of a peri-implant soft tissue dehiscence/deficiency (PSTD) is not a rare finding. Despite multiple previous attempts aimed at correcting the PSTDs, a classification of these conditions has not yet been proposed. This lack in the literature may also lead to discrepancies in the reported treatment outcomes and thus misinform the clinician or the readers. The aim of the present article was therefore to present a classification of peri-implant PSTD at a single implant site. METHODS: Four classes of PSTDs were discussed based on the position of the gingival margin of the implant-supported crown in relation to the homologous natural tooth. In addition, the bucco-lingual position of the implant head was also taken into consideration. Each class was further subdivided based on the height of the anatomical papillae. RESULTS: Subsequently, for each respective category a surgical approach (including bilaminar techniques, the combined prosthetic-surgical approach or soft tissue augmentation with a submerged healing) was also suggested. CONCLUSION: This paper provides a new classification system for describing PSTDs at single implant sites, with the appropriate recommended treatment protocol.
