Full-mouth rehabilitation with lithium disilicate ceramic crowns in hypoplastic amelogenesis imperfecta: a case report and review of literature.

BACKGROUND: Amelogenesis imperfecta (AI) is a group of genetic disorders characterized by tooth discoloration and enamel defects. Patients with AI always exhibit generalized attrition and defective tooth structure, leading to the loss of occlusal vertical dimension (OVD). Appropriate rehabilitation is challenging and essential to improve patients' aesthetics and function. CASE PRESENTATION: This case report presents a comprehensive management of a 30-year-old woman with hypoplastic AI. A 52-month follow-up revealed satisfactory full-mouth rehabilitation performances of lithium disilicate ceramic crowns after clinical crown lengthening, with increased vertical dimension. CONCLUSIONS: Patients with severe hypoplastic AI require proper full-mouth rehabilitation. Using full-crown lithium disilicate restorations to increase the OVD by 2‒4 mm is a safe and predictable recommendation for such cases. In addition, patients with AI require complex and comprehensive management. The long-term effects of full-mouth rehabilitation with lithium disilicate ceramic crowns still necessitate further follow-ups.

Pain assessment, cognitive and cortical changes with full mouth rehabilitation in a group of children.

BACKGROUND: A change in professionals' perspectives on the value of general anesthesia (GA) for pediatric patients, including those with disabilities, medical conditions, severe oral issues, and challenging behaviors. Full-mouth rehabilitation under GA allows for the comprehensive treatment of all oral health problems in a single visit, without requiring the child's active participation. Extensive dental problems are often associated with severe dental pain, which can impact cognitive function, including perception, attention, memory, reasoning, language, communication, and executive functions. Individuals experiencing pain tend to perform less optimally cognitively. AIM: This study aimed to investigate changes in cognition, brain function, and cortical alterations in children who underwent extensive dental rehabilitation under GA. PATIENTS ANDMETHODS: Thirty uncooperative, healthy children aged 6-12 with extensive dental issues were enrolled. Pain levels were assessed using the FLACC and WBFPS scales before treatment, one week after, and three months later. Cognitive assessments, including the WCST, processing speed, digit span, and Trail Making Test, as well as EEG measurements, were also performed. RESULTS: The results showed a significant improvement in pain levels reported by the children or their caregivers after the dental procedures, both at one week and three months. All cognitive measures, such as digit span, processing speed, and WCST performance, demonstrated substantial improvements after the treatment. The Trail Making Test also exhibited statistically significant variations before and after the dental procedures. Additionally, the MOCA test revealed a notable improvement in cognitive skills following the treatment. Furthermore, the EEG power ratio, an indicator of changes in the power balance within each frequency band, showed a statistically significant difference after the dental procedures. CONCLUSION: the findings of this study suggest that full-mouth rehabilitation under GA can lead to improved pain management, as well as enhanced cognitive and brain functions in children. FUTURE PERSPECTIVES: More clinical studies with a longer follow-up period and a different age range of children are required to investigate the connection between brain function and oral rehabilitation involving restorations or occlusion issues.

Treatment with a CAD-CAM-fabricated, double-crown-retained, removable partial denture: A clinical report.

This clinical report describes treatment with a double-crown-retained, removable partial denture with a 2-year follow up. Primary and secondary crowns and a removable partial denture metal-alloy framework were fabricated using computer aided design and computer aided manufacturing (CAD-CAM) and milled from cobalt-chromium (Co-Cr) alloy.

Staged extractions and implant placement in a periodontally compromised patient: A clinical report.

Staging the extraction of selected teeth in a periodontally compromised patient during complete mouth rehabilitation has advantages, including avoiding a transitional complete denture, keeping the patient with a fixed prosthesis throughout the treatment without the need to immediately load the implants, maintaining the interdental papillae, and providing comfort for the patient. The need for a multistep extended treatment and additional cost are the main disadvantage of this approach. This clinical report describes the clinical steps and follow-up of a staging approach and implant placement in a periodontally compromised patient with excessive gingival display to achieve a good functional and esthetic result.

Esthetic Rehabilitation of Retained Primary Teeth-A Conservative Approach.

With the advancement in ceramic restorations bonded to tooth structure, the treatment has become a feasible and conservative option to restore teeth with alteration in shape when owing to high demand in esthetics, with or without minimum tooth preparation. This article describes a report of a 32-year-old woman who was dissatisfied with her smile. The patient reported that she still had deciduous teeth, and that the maxillary lateral incisors had been restored with direct resin composite to correct the teeth shape. After discussing the restorative possibilities, a decision was made to place all-ceramic crowns (lithium disilicate glass-ceramic) with minimal tooth preparation, which figures as a conservative full-coverage approach. An esthetic outcome resembling a natural-looking smile resulted in the patient's satisfaction. Bonding of all-ceramic crowns onto minimally prepared deciduous teeth figures as a conservative treatment in case of partial anodontia, which decreases the chance of root resorption induced by trauma and benefits from good adhesion to enamel.

A long-term clinical study on individuals with amelogenesis imperfecta.

BACKGROUND: The aims of this study are to present sociodemographic and familial characteristics, clinical and systemic findings, dental treatment needs, and concomitant dental anomalies in patients with amelogenesis imperfecta (AI) and to evaluate time-varying conditions in these long-term follow-up patients. MATERIALS AND METHODS: Records of patients with AI who were examined in the Department of Pediatric Dentistry between 1999 and 2017 were reviewed. Information about sociodemographic characteristics, history of AI and consanguinity in family, systemic conditions, reasons for referral to the clinic, oral hygiene habits and gingival health, occlusion findings, and performed treatments were gathered. Dental anomalies in radiographs were also evaluated. Baseline and final situations of the patients were assessed. Statistical analyses were performed. RESULTS: Of 75 patients aged 3-15 years with follow-ups up to 12 years, 34 had AI in their families and 15 were born from consanguineous marriages. Nephrocalcinosis has been observed in 5 patients. Main reasons for referral to the clinic were related to esthetic and hypersensitivity concerns. Twenty-two patients had gingivitis, and during follow-up process, gingival problems could not be completely prevented due to poor oral hygiene habits. Vertical dimension loss, open-bite, and cross-bite were seen in 16, 15, and 10 patients, respectively. Of the patients, 63% experienced restorative, 33% stainless steel crown, 17% endodontic, 8% prosthetic treatments, and 24% had retreatment needs. Concomitant dental anomalies were dens invaginatus, taurodontism, ectopic eruption, delayed eruption, hypodontia, and pulpal calcification. CONCLUSION: Early diagnosis and interventions considering the time-varying conditions with long-term follow-ups provide significant improvements in clinical maintenance of patients with AI.

Contemporary management and full mouth rehabilitation of a patient with Sjögren syndrome.

Sjögren syndrome is a chronic autoimmune disorder with xerostomia, increased tooth wear, high rates of caries, and repeated failure of dental restorations as the main oral symptoms. These render the prosthetic treatment challenging. This clinical report describes a contemporary approach to the treatment of a patient with Sjögren syndrome using translucent multilayered monolithic zirconia restorations and focuses on the treatment protocols before, during, and after the prosthetic treatment.

Predictable prosthetic space maintenance during staged complete-mouth rehabilitation.

Staged complete-mouth rehabilitation to accommodate a patient's financial constraints during the course of treatment is presented. Clear acrylic resin added to the anterior cameo surface of the maxillary fixed complete denture (FCD) served as a space maintainer. The restoration of the maxillary FCD addressed the patient's chief complaint. By adding the space maintainer, supraeruption of mandibular anterior teeth and encroachment of the prosthetic space, which could have resulted in additional treatment, was avoided. During the second stage of the complete-mouth rehabilitation, zirconia restorations were used to restore the mandibular arch to the maxillary FCD after straightforward removal of the space maintainer. This allowed a smooth transition after a delay in treatment without having to modify the previous treatment.

Oral rehabilitation with implant-supported fixed dental prostheses of a patient with cleidocranial dysplasia.

This clinical report describes the oral rehabilitation with implant-supported fixed dental prostheses in the maxilla and mandible of a patient with cleidocranial dysplasia. Cone-beam computed tomography and a tilted implant protocol in the mandible helped to establish a conservative approach for bone preservation, prevent surgical complications, enable proper implant positioning to avoid anatomic structures, and support the fixed dental prostheses.

Effects of mouth rehabilitation with removable complete dentures on stimulus perception and the electromyographic activity of the orbicularis oris muscle.

STATEMENT OF PROBLEM: Many elderly individuals are rehabilitated with removable complete dentures, which require an initial adaptation period for both oral perception and the perioral muscles. Studies assessing the changes in stimulus perception and the electromyographic (EMG) activity of the orbicularis oris muscle shortly after conventional complete denture insertion are lacking. PURPOSE: The purpose of this clinical study was to evaluate the effect of mouth rehabilitation with removable complete dentures on stimulus perception and the EMG activity of the orbicularis oris muscle. MATERIAL AND METHODS: This study was approved by the Human Research Ethics Committee of the Araçatuba Dental School (São Paulo State University). Fifteen participants who had worn their removable complete dentures for at least 5 years and needed rehabilitation with new prostheses were enrolled in the study. A perception questionnaire was applied, and surface EMG examinations of the orbicularis oris muscle during rest, suction of water with a straw, and pronunciation of the syllables /bah/, /mah/, /pah/, and the word 'Mississippi' were performed before (T0) and 30 (T1) and 100 (T2) days after insertion of the new prostheses. The data were analyzed with the Cochran Q test, McNemar test, 2-way repeated measures ANOVA, and honestly significant difference (HSD) Tukey test (α=.05). RESULTS: Significant improvement was reported in the perception questionnaire in terms of the oral discomfort sensation in the T2 period. EMG activity decreased during rest and suction after insertion of the new prostheses. A statistical difference between the upper and lower fascicles of the orbicularis oris muscle was detected, with a decrease of EMG activity between the T0 and T1 periods on the lower fascicle, except for when pronouncing the /pah/ syllable. CONCLUSIONS: Mouth rehabilitation with removable complete dentures decreased oral discomfort and, depending on the oral function, decreased or increased EMG activity of the orbicularis oris muscle. In addition, the lower fascicle was more active than the upper fascicle during rest and most functional activities.

Minimally Invasive Complete Mouth Reconstruction using Full-Contour Ceramic Veneers: A Clinical Report.

This case report illustrates a full-mouth rehabilitation for a patient that presented with severe non-carious tooth surface loss. The patient was restored following a minimally invasive tooth preparation, with 28 full-contour veneers. The patient was evaluated at baseline and at 2, 9, and 13 months following cementation to assess the integrity of the restorations, the proximal and occlusal contacts, pulp vitality, and tooth mobility. After 13 months, no postoperative sensitivity was reported. In addition, no secondary caries, loss of tooth vitality, or chipping or fractures of the veneers were detected. The clinical outcome of using a minimally invasive adhesive technique was an esthetic, mechanical, and biological success.

Prosthodontic Rehabilitation for a Patient with Down Syndrome: A Clinical Report.

Patients with Down syndrome can present with a variety of oral manifestations such as hypodontia, periodontal disease, premature tooth loss, reduced salivary flow, crowding of teeth in both arches, and decreased occlusal vertical dimension. The intellectual ability of people with Down syndrome varies widely. They present with a mild-to-moderate intellectual disability that restricts their ability to communicate and adjust to their environment, which can add complexity in the overall dental treatment. There is little information in the literature regarding the prosthodontic rehabilitation for patients with Down syndrome in combination with dental implant placement. An implant-assisted removable partial dental prosthesis can be a cost-effective treatment alternative for carefully chosen patients with Down syndrome. This article presents the treatment of a 44-year-old male patient with Down syndrome and a moderate intellectual disability who presented with congenital and acquired tooth loss with significant occlusal discrepancies. The treatment included a prosthodontic approach that used a single dental implant, which will be described and illustrated in this article.

Computer-assisted technologies used in oral rehabilitation and the clinical documentation of alleged advantages - a systematic review.

The objective of this systematic review is to identify current computer-assisted technologies used for managing patients with a need to re-establish craniofacial appearance, subjective discomfort and stomatognathic function, and the extent of their clinical documentation. Electronic search strategies were used for locating clinical studies in MEDLINE through PubMed and in the Cochrane library, and in the grey literature through searches on Google Scholar. The searches for commercial digital products for use in oral rehabilitation resulted in identifying 225 products per November 2016, used for patient diagnostics, communication and therapy purposes, and for other computer-assisted applications in context with oral rehabilitation. About one-third of these products were described in about 350 papers reporting from clinical human studies. The great majority of digital products for use in oral rehabilitation has no clinical documentation at all, while the products from a distinct minority of manufacturers have frequently appeared in more or less scientific reports. Moore's law apply also to digital dentistry, which predicts that the capacity of microprocessors will continue to become faster and with lower cost per performance unit, and innovative software programs will harness these improvements in performance. The net effect is the noticeable short product life cycle of digital products developed for use in oral rehabilitation and often lack of supportive clinical documentation. Nonetheless, clinicians must request clinically meaningful information about new digital products to assess net benefits for the patients or the dental professionals and not accept only technological verbiage as a basis for product purchases.

Oral features and computerized rehabilitation of a young patient with CHARGE syndrome using minimally invasive long-term interim CAD-CAM restorations.

Patients with CHARGE syndrome (where CHARGE stands for coloboma of the iris or retina, heart defects or cardiac malformations, atresia/stenosis of the choanae, retardation of growth and development, genital anomalies, and ear abnormalities) present several orofacial anomalies. Their treatment depends on the specific type of manifestation. To perform the complex oral rehabilitation and achieve a conservative, esthetic, and functional exploration of the definitive treatment goal, computer-aided design and computer-aided manufacturing (CAD-CAM) polymers can be used as long-term interim restorations. This article reports the treatment of a young patient with CHARGE syndrome combined with oral alterations. CAD-CAM polymers offer an intermediate treatment with satisfying esthetics and function at low biological cost until bone growth is completed. This period facilitates additional planning for the definitive restoration.

Facially generated and cephalometric guided 3D digital design for complete mouth implant rehabilitation: A clinical report.

Harmony among the teeth, lips, and facial components is the goal of prosthodontic treatment, whether performed by conventional or digital workflow methods. This clinical report describes a facial approach to planning computer-guided surgery and immediate computer-aided designed and computer-aided manufactured (CAD-CAM) interim complete-arch fixed dental prostheses on immediately placed dental implants with a digital workflow. A single clinical appointment for data collection included dentofacial documentation with photographs and videos. On these photographs, facial reference lines were drawn to create a smile frame. This digital smile design and sagittal cephalometric analysis were merged with 3-dimensional scanned casts and a cone beam computed tomographic file in virtual planning software, thus guiding virtual waxing and implant positioning. Computer-guided implant surgery and CAD-CAM interim dental prostheses allowed esthetic and functional rehabilitation in a predictable manner and integrated with the patient's face.

Complete mouth rehabilitation and gastroesophageal reflux disease: Conventional and contemporary treatment approaches.

This report describes the diagnosis and prosthodontic management of 2 patients with a history of chronic gastroesophageal reflux disease and worn dentition. Different treatment approaches were used for oral rehabilitation. Use of conventional and contemporary restorative materials resulted in functional and esthetic prosthodontic rehabilitation with a favorable prognosis.

Impact of oral rehabilitation on patients with head and neck cancer: A study using the Liverpool Oral Rehabilitation Questionnaire and the Oral Health Impact Profile-14.

STATEMENT OF PROBLEM: The treatment of oral cancers affects oral functions and quality of life (QOL). Dental rehabilitation is a major step toward enhancing quality of life after controlling the disease. The effects of the disease, treatment, and rehabilitation need to be evaluated to assess oral health-related QOL. The Liverpool Oral Rehabilitation Questionnaire version 3 (LORQv3) and Oral Health Impact Profile-14 (OHIP-14) are specific assessment questionnaires of oral rehabilitation. PURPOSE: The purpose of this study was to assess the impact of oral rehabilitation on patients with head and neck cancer by using the LORQv3 and OHIP-14 questionnaires and to discover and document specific patient-derived problems related to the issues of oral rehabilitation. MATERIAL AND METHODS: The LORQv3 and OHIP-14 questionnaires were administered to 60 participants with oral cancer, who were in need of oral rehabilitation. They were asked to rate their dental problems on a Likert scale before fabrication of their prostheses (baseline) and at the 3-month follow-up visit after prosthetic rehabilitation. Paired comparison was done using the Wilcoxon signed rank test according to the distribution, and Cronbach alpha was used to assess internal consistency. Subscale scores were determined by mean value (α=.05). RESULTS: For the LORQv3 questionnaire, a 10% to 27% improvement was found in the domain of oral function, and a 20% improvement in orofacial appearance, with improvement in patient satisfaction with the prosthesis. Using the OHIP-14 questionnaire, a 45% to 67% improvement was generally seen in all domains. CONCLUSIONS: After assessment using the LORQv3 and OHIP-14 questionnaires, prosthetic rehabilitation was seen to contribute to the betterment of patients with head and neck cancer.

Prosthetic rehabilitation in a pediatric patient with hypohidrotic ectodermal dysplasia: a case report.

Hypohidrotic ectodermal dysplasia (HED) is a rare ectodermal disease with a systemic expression. Oral abnormalities are common and may include hypodontia and shape irregularities in the primary and permanent dentitions. Rehabilitation of the dental arches in pediatric patients with HED is a challenge because HED is a multifactorial disease that demands a complicated treatment approach and most dentists have limited experience or training in the necessary treatment. In addition, pediatric patients often lack the patience or ability to cooperate with complex prosthetic treatment. This case report describes a simplified technique used to fabricate complete dentures for a 4-year-old HED patient in 4 sessions.

The face scan as a means for the visualization of complex prosthetic reconstructions.

The face scan can serve as a means for the visualization of planes relevant for extensive prosthetic reconstructions. The key prerequisite is the availability of data in stl format for further processing in different software programs. The method is described in this article by a patient case.

Rethinking the traditional full-mouth rehabilitation by applying minimal prosthetic dentistry for maximum patient benefit.

The field of dentistry is an ever-evolving discipline. A marked rise in the use of endosseous implants, adhesive ceramic bonding, and composite resins, as well as continued patient desire for minimally invasive procedures, has created a new conservative era in the practices of many restorative dentists. These trends, coupled with the significant financial impact associated with the reconstruction of failing, worn, and esthetically compromised dentitions, have facilitated a paradigm shift in the way that individual patient cases are being treatment planned today. Applying restraint to conventional practices involving the unnecessary gross removal of hard tooth structure is both a skill that needs to be cultivated as well as an evident obligation to the patient. A case report demonstrates the utilization of multiple restorative materials to provide a minimally invasive definitive treatment that was biomechanically, esthetically, and financially satisfactory for the patient.
