Multidisciplinary full-mouth rehabilitation using minimally invasive dental implant therapy: a report on three different clinical scenarios.

Conventional operative dental procedures are being revisited with an approach that seeks to preserve the original tissue as much as possible. Implant dentistry has also seen the advent of various techniques which make minimal alteration to natural tissue. The flapless technique involves implant placement either through a freshly extracted socket or through a tansmucosal punch hole, without elevating mucoperiosteal flap. This paper presents a report on three cases of patient centric, conventional dental implant-based full-mouth rehabilitation, which was successfully carried out using the flapless technique, under varied clinical situations. Each case showed a favourable outcome in terms of restoration of the form and function of the patient's dentition.

Demystify Treatment Planning With a Correct Functional Diagnosis.

Obtaining an accurate assessment of the causes of severe dental destruction is crucial when planning a clinical workflow for full-mouth rehabilitation cases. Some cases that initially appear extremely challenging may be surprisingly straightforward, especially if the patient presents with an acceptable functional occlusion. In the seemingly highly complex case presented, only a Lucia jig was required to obtain a reliable restorative reference point for the full-mouth rehabilitation. Increasing the vertical dimension of occlusion allowed for predictable restoration of function and esthetics. The treatment was completed in phases for patient comfort, and the final outcome provided the patient with regained confidence in his smile and comfort when eating.

Dental approaches in children with congenital heart disease treated under general anesthesia for oral rehabilitation.

BACKGROUND: Children with congenital heart disease (CHD) are at high risk of contracting oral diseases. The aim of this study is to investigate dental procedures to prevent the risk of infective endocarditis in children with CHD. MATERIAL AND METHODS: 146 patients aged 2-14 years, in need of prophylaxis before cardiovascular surgery and who had filled out anamnesis records, were considered. Dental caries in all the children with CHD was reported as the number of decayed, missing and filled teeth (DMFT). RESULTS: There was a significant strong positive relationship between the pre-oral rehabilitation DMF-T/dmf-t scores and the number of caries patients (r=0.95, p=0.01). There was no significant correlation between the pre-oral rehabilitation DMF-T/dmf-t scores and both tooth loss (r=0.14, p=0.09) and the number of restorations (r=0.11, p=0.17). In addition, there was no significant correlation between the post-oral rehabilitation DMF-T/dmf-t scores and the prevalence of dental caries. A positive and moderately strong correlation was found between the post-oral rehabilitation DMF-T/dmf-t scores and the number of missing teeth (r=0.56, p=0.01), while there was a positive and strong relationship between the post-treatment DMF-T/dmf-t scores and the number of fillings (r=0.62, p=0.01). CONCLUSIONS: Extraction should be considered when providing oral rehabilitation, rather than endodontic and deep restorative treatments.

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.

Introdução: O tratamento de tumores malignos ou benignos, podem resultar em procedimentos cirúrgicos, como a maxilectomia parcial ou total, gerando comunicação bucosinusal nos pacientes. Uma forma de resolver estas alterações maxilofaciais é através do tratamento reabilitador com próteses obturadoras a fim de restabelecer a função mastigatória, estética, fonética e psicológica. Objetivo: o objetivo deste trabalho foi relatar o caso clínico de um paciente oncológico que foi reabilitado com prótese obturadora devido à maxilectomia por neoplasia maligna de seio maxilar. Relato de caso: Paciente de 62 anos, sexo masculino, procurou atendimento odontológico no Centro de Oncologia Bucal da Universidade Estadual Paulista "Júlio de Mesquita Filho" (UNESP) de Araçatuba ­ SP após a realização de uma maxilectomia parcial com comunicação bucosinusal e foi encaminhado para o Curso de Especialização em Prótese Dentária da Faculdade de Odontologia ­ Unesp/Araçatuba-SP para a reabilitação. Foi proposto, primeiramente a realização da prótese obturadora para fechar a comunicação bucosinusal e uma prótese total inferior para o arco antagonista e, posteriormente, a realização de uma prótese facial. Conclusão: O tratamento reabilitador com próteses obturadoras possui um bom resultado estético e funcional, favorecendo uma melhor função mastigatória e fonética, e melhorando consideravelmente a condição psicológica que é muito afetada nos pacientes submetidos a maxilectomia total ou parcial, sendo necessário uma boa interação com toda a equipe multiprofissional envolvida para que haja um melhor tratamento integrado para a reabilitação e melhora da qualidade de vida(AU)

Introduction: The treatment of malignant or benign tumors can result in surgical procedures, such as partial or total maxillectomy, generating oral communication in patients. One way to resolve these maxillofacial changes is through rehabilitative treatment with obturator prostheses in order to reestablish masticatory, aesthetic, phonetic and psychological function. Objective: the objective of this work was to report the clinical case of a cancer patient who was rehabilitated with an obturator prosthesis due to maxillectomy for malignant neoplasia of the maxillary sinus. Case report: A 62-year-old male patient sought dental care at the Oral Oncology Center of the Universidade Estadual Paulista "Júlio de Mesquita Filho" (UNESP) in Araçatuba ­ SP after undergoing a partial maxillectomy with oral cavity and was referred for the Specialization Course in Dental Prosthesis at the Faculty of Dentistry ­ Unesp/Araçatuba-SP for rehabilitation. It was proposed, firstly, to create an obturator prosthesis to close the bucosinusal communication and a total lower prosthesis for the antagonistic arch and, later, to create a facial prosthesis. Conclusion: Rehabilitative treatment with obturator prostheses has a good aesthetic and functional result, favoring better chewing and phonetic function, and considerably improving the psychological condition that is greatly affected in patients undergoing total or partial maxillectomy, requiring good interaction with the entire the multidisciplinary team involved so that there is better integrated treatment for rehabilitation and improved quality of life

Evaluation of Risk Factors associated with Caries Development after Full-mouth Rehabilitation for Early Childhood Caries Under General Anesthesia.

AIM: To evaluate the risk factors associated with caries development after full-mouth rehabilitation for early childhood caries (ECC) under general anesthesia. MATERIALS AND METHODS: A total of 100 children diagnosed with ECC requiring full-mouth rehabilitation under general anesthesia were recruited for the study. At baseline, caries status, plaque index, Streptococcus mutans count, and Lactobacillus count were evaluated. The risk assessment for caries was evaluated using a cariogram. Children were recalled after 12 months for evaluation. All children returned for the recall and data was recorded at the recall visit. Children were grouped into caries-free or caries recurrent based on the absence or presence of caries. Chi-square tests and student's t-test were used for statistical analysis using the statistical package for the social sciences (SPSS), version 23. RESULTS: All 100 children returned for follow-up. 76% of the children developed new carious lesions in a period of 1 year. A statistically significant association between caries recurrence and S. mutans count and caries risk assessment (CRA) score was found (p < 0.001). No significant associations were seen between parental education levels and the oral health practices of the child. CONCLUSION: Children treated under full-mouth rehabilitation for ECC under general anesthesia are at risk for developing new carious lesions after treatment. New carious lesions are strongly correlated with the presence of S. mutans, and high cariographic risk scores serve as an indication of future caries. Early childhood caries may be avoided if children are more diligent in practicing good dental hygiene. CLINICAL SIGNIFICANCE: Relapse of caries after full-mouth rehabilitation under general anesthesia can affect the quality of life of children. Preventive measures should be initiated and reinforced to prevent the occurrence of new carious lesions after full-mouth rehabilitation.

A novel approach to full-mouth rehabilitation of dentinogenesis imperfecta type II: Case series with review of literature.

RATIONALE: Dentinogenesis imperfecta (DI) is an autosomal-dominant disorder. The most common clinical manifestations, including obliterated tooth tissues and severe tooth wear, usually lead to tooth extractions. It remains a great challenge for dentists to preserve the residual tooth tissue and establish the esthetics and occlusion of dentitions. PATIENTS CONCERNS: 25-year-old twin sisters, who had suffered from dentinogenesis imperfecta type II for more than 10 years, presented with continuous tooth wear and discomfort from wearing a removable partial denture for more than 3 years. DIAGNOSIS: Intraoral examination showed extensive tooth wear with enamel exfoliation and typical amber-brown color with an opalescent discoloration. Their panoramic radiographs revealed completely obliterated tooth tissues and severe tooth wear. INTERVENTIONS AND OUTCOMES: The dentitions were restored with post-and-core crowns and pin lays after preparing root post paths and pin holes guided by computer-aided design/computer-aided manufacturing (CAD/CAM) procedures, resulting in a successful repair. LESSONS: Severe tooth wear and tooth tissue obliteration are typical clinical manifestations in DI-affected dentitions, increasing the complexity and difficulty in dental restorations. Early diagnosis and appropriate treatments are essential to achieve a favorable prognosis. CAD/CAM procedures, permitting accurate and effective treatment, possess promising potential in the treatment of DI-affected dentitions.

CAD/CAM full-mouth rehabilitation of an elderly patient: One-piece digital complete denture meets multilayered zirconia with gradient technology.

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.

An esthetic minimally invasive rehabilitation performed with a fully digital workflow and hybrid restorative approach.

AIM: The aim of the present study was to demonstrate that fully digital workflows can provide predictable esthetic and functional outcomes. MATERIALS AND METHODS: The present clinical case report provides a step-by-step documentation of a full-mouth rehabilitation planned and performed with a fully digital approach utilizing an adhesive and no-prep method. After assessing the patient's needs, a treatment plan was established that considered the patient's functional and esthetic requests. The overlap of 2D images and 3D models and facial scans of the patient allowed the digital previsualization of the esthetic result by implementing the "copy-paste" approach to restore the maxillary anterior sextant. CONCLUSION: The final outcome was satisfactory in terms of esthetics, function, and soft tissue health.

Is scanning under rubber dam isolation a feasible approach for the execution of indirect restorations? / O escaneamento sob isolamento absoluto é uma técnica viável para execução de restaurações indiretas?

There is a constantly growing prevalence of tooth wear in dentistry. The present case report describes a rehabilitation through ceramic restorations of a severely worn dentition based on a conservative intervention, adequate restorative material selection, and adhesive bonding strategies. A 36-year-old patient with a mainly esthetic complaint presented with signs of tooth wear caused by erosion and attrition. Preparations were performed guided by the diagnostic planning. The full-mouth rehabilitation, combined with the correction of the vertical dimension of occlusion, was split into quadrants, and lithium disilicate partial restorations were fabricated. The proposed rehabilitation was based on the maximal preservation of the remaining tooth structure and the adequate selection of restorative materials and adhesive bonding strategies.

Rendimiento Clínico de las Restauraciones Adhesivas con Resina Compuesta en Casos de Pacientes con Desgaste Severo e Incremento de Dimensión Vertical: Revisión de Literatura Sistematizada / Clínical Performance of Adhesive Restorations with Composite Resin in Cases of Patients with Severe Wear and Increased Vertical Dimension: Systematized Literature Review

El desgaste dental severo se describe como la pérdida sustancial de la estructura dental, con exposición de la dentina y pérdida significativa de igual o más de 1/3 de la corona clínica. El uso de materiales compuestos de resina permite al clínico ser más conservador, debido a su aplicación mínimamente invasiva. Además de ello, son relativamente económicas, proporcionan buena estética general, así como un buen rendimiento y facilidad en la reparación. El objetivo de esta revisión de literatura sistematizada es recopilar información disponible en la literatura referente a cuál es el rendimiento clínico de las restauraciones adhesivas con resina compuesta en casos de pacientes con desgaste severo e incremento de la dimensión vertical como objetivo rehabilitador. Se analizaron artículos entre los años 2000 y 2022, seleccionando cuatro bases de datos (Pubmed, Scopus, Scielo y Web of Science). Para identificar los descriptores se utilizó los Medical subject headings (Mesh): Tooth Wear, Composite Restorations, Resin y Oral Rehabilitation. No se aplicó restricciones de idioma, país de origen, autor o lugar de publicación donde se realizó el estudio. Como resultado de la búsqueda se obtuvieron 71 artículos, de los cuales se seleccionaron 5 que cumplieron con los criterios de elegibilidad para ser considerados en la revisión de literatura sistematizada. Se encontró un promedio de tasa de éxito ente el 89,4 % - 100 % en un promedio total de 5.2 años de seguimiento. Se puede concluir, hasta donde se tiene conocimiento en la literatura científica disponible, que el tratamiento de restauraciones adhesivas con resinas compuestas en pacientes con desgaste severo es recomendable, enfocado en un periodo a corto-mediano plazo (3-5 años), siendo una opción de tratamiento económica y mínimamente invasiva.

Severe tooth wear is described as the substantial loss of tooth structure, with dentin exposure and significant loss of equal to or more than 1/3 of the clinical crown. The use of resin composite materials allows the clinician to be more conservative, due to its minimally invasive application. In addition to this, they are relatively inexpensive, provide good general aesthetics, as well as good performance and ease of repair. The objective of this systematic literature review is to collect information available in the literature regarding the clinical performance of adhesive restorations with composite resin in cases of patients with severe wear and increase in the vertical dimension as a rehabilitation objective. Articles between the years 2000 and 2022 were analyzed, selecting four databases (Pubmed, Scopus, Scielo and Web of Science). To identify the descriptors, the Medical subject headings (Mesh) were used: Tooth Wear, Composite Restorations, Resin and Oral Rehabilitation. No language, country of origin, author or place of publication restrictions where the study was conducted were applied. As a result of the search, 71 articles were obtained, of which 5 were selected that met the eligibility criteria to be considered in the systematic literature review. An average success rate between 89.4 % - 100 % was found in a total average of 5.2 years of follow-up. It can be concluded, to the best of our knowledge in the available scientific literature, that the treatment of adhesive restorations with composite resins in patients with severe wear is recommendable, focused on a short-medium term period (3-5 years), being a Inexpensive and minimally invasive treatment option.

AIM: To evaluate the change in quality of life, dental fear, and dental anxiety in young children following full-mouth dental rehabilitation under general anesthesia for early childhood caries. MATERIALS AND METHODS: About 200 children who were diagnosed with early childhood caries requiring full-mouth rehabilitation under general anesthesia were recruited after obtaining parental consent. Oral health-related quality of life (OHRQoL) was measured using the Early Childhood Oral Health Impact Scale (ECOHIS). Dental fear was evaluated using Children's Fear Survey Schedule-Dental Subscale and dental anxiety was evaluated using the Facial Image Scale. Scores were taken on the day of intervention, and after 14 days when the child reported for posttreatment follow-up. RESULTS: All 200 participants returned for a follow-up visit after 2 weeks. The child impact section was reduced from 15.7 ± 4.1 to 7.7 ± 1.9 after treatment. The family impact section was reduced from 9.6 ± 2.7 to 3.5 ± 2.6 after treatment. A statistically significant difference was seen in both sections when pre-and posttreatment values were compared (p < 0.001). The total ECOHIS showed statistically significant improvement as the pretreatment score of 21.6 ± 9.5 reduced to 11.2 ± 4.2 showing 51.9% improvement in OHRQoL after full-mouth rehabilitation under general anesthesia was done (p < 0.001). Dental fear and anxiety among the participants showed a statistically significant reduction after treatment was done and most participants were found to be less fearful of doctors, dentists, and injections after treatment. CONCLUSION: Full-mouth rehabilitation was found to be a reliable treatment modality to improve the OHRQoL of children suffering from early childhood caries. CLINICAL SIGNIFICANCE: Significant improvement was seen in the OHRQoL within 2 weeks after treatment and most participants were found to be less anxious and fearful toward dentists and dental treatment. Comprehensive dental rehabilitation under general anesthesia has been proven to be an effective treatment modality for early childhood caries and a productive treatment technique to reduce dental fear and anxiety.

Effect of aging and thermocycling on flexural strength of PEEK as a provisional restoration for full mouth rehabilitation - An In vitro study.

Introduction: To compare the flexural strength of autopolymerizing poly methyl methacrylate resins (PMMA) resin, CAD/CAM milled PMMA and CAD/CAM milled poly ether ether ketone (PEEK) when used as provisional restorative materials for long span situations in full mouth rehabilitation after aging and thermocycling. Materials and Methods: Sixty samples (25 mm × 2 mm × 2 mm) were fabricated using autopolymerizing PMMA resin (GROUP I), CAD/CAM milled PMMA (GROUP II) and PEEK (GROUP III). The groups were subdivided into A and B and subjected to 7 days of aging and 500 cycles of thermocycling (subgroup A) and 14 days of aging and 1000 cycles of thermocycling (subgroup B), respectively, and flexural strength was evaluated using a three-point bend test. The data were analyzed with student t test and pair-wise comparison of mean values was done by ANOVA. Results: The flexural strength of PEEK subjected to 7 days of aging and 500 cycles of thermocycling (III (A) - 6628.70 MPa) was the highest among all groups followed by PEEK subjected to 14 days of aging and 1000 cycles of thermocycling (III (B) - 3760.50 MPa). Conclusion: The mean flexural strength of PEEK was statistically significant than the other two materials tested and hence can be recommended for use as a provisional restorative material for long span situations in full mouth rehabilitation. However, the mean flexural strength of PEEK reduced approximately by 44% when subjected to further aging.

Associated short and regular implants for complete denture retention in an atrophic mandible: clinical follow-up / Implantes corto y regular asociados para retención de prótesis completa en mandíbula atrófica: seguimiento clínico / Implantes curto e regular associados para retenção de prótese total em mandíbula atrófica: acompanhamento clínico

Objective: to present the radiographic clinical follow-up of the prosthetic rehabilitation of a patient with an atrophic mandible, with the installation of short implants associated with an implant of regular length. Method: case report of a completely edentulous patient with an atrophic mandible and a 6-year radiographic clinical follow-up conducted at the dental clinic of the Federal University of Piauí, Teresina, from February 2011 to January 2020. After collecting sociodemographic data, health records, clinical radiographic examinations, and prosthetic surgical planning, four dental implants were installed between the mental foramina. After three months, mini-conical abutments and a fixed prosthesis screwed onto the implants were installed and monitored every six months for a period of six years. Results: the clinical evaluation revealed tissue stability without significant peri-implant changes after the follow-up period. Radiographically, bone resorption was not observed around the implant. Stability of the prosthesis and absence of prosthetic complications were observed during the follow-up period. Conclusion: short implants associated with regular-length implants can be placed in the anterior region of an atrophic mandible for rehabilitation with fixed complete dentures.

Objetivo: apresentar o acompanhamento clínico radiográfico da reabilitação protética de um paciente com mandíbula atrófica com a instalação de implantes curtos associados a um implante de comprimento regular. Método: relato de caso de uma paciente desdentada total com mandíbula atrófica, e acompanhamento clínico radiográfico de seis anos, realizado na clínica odontológica da Universidade Federal de Piauí, Teresina, no período de fevereiro de 2011 a janeiro de 2020. Após coleta de dados sociodemográficos e registro de saúde, exames clínicos radiográficos e planejamento cirúrgico protético, foram instalados quatro implantes dentários entre os forames mentonianos. Após o período de três meses foram instalados mini pilares cônicos e uma prótese fixa aparafusada sobre os implantes que foi acompanhada a cada seis meses por um período de seis anos. Resultados: as avaliações clínicas mostraram estabilidade tecidual sem alterações peri-implantares significativas após o período de acompanhamento. Radiograficamente foi observada a manutenção sem reabsorção óssea ao redor dos implantes. A estabilidade da prótese e a ausência de complicações protéticas foram observadas clinicamente durante o período de acompanhamento. Conclusão: os implantes curtos associados a implante de comprimento regular podem ser colocados na região anterior da mandíbula atrófica para reabilitação com prótese total fixa.

Managing the transition to a complex full mouth rehabilitation utilizing injectable composite.

OBJECTIVE: This article describes the use of flowable injectable composite resins to facilitate transitional treatment of a complex complete mouth rehabilitation. CLINICAL CONSIDERATIONS: Some patients require urgent and complex complete mouth rehabilitations that are time and cost intensive. Financial considerations can prevent some patients from pursuing treatment. This can result in the oral conditions worsening over time and compromising the long-term prognosis of the teeth. CONCLUSIONS: Injectable composite resins can be used as a transitional bonding material for complex cases using an injection molding technique utilizing clear indices obtained from a diagnostic waxing. This allows for a full mouth rehabilitation to be performed in a single appointment, producing instant results. CLINICAL SIGNIFICANCE: Transitioning with injectable composite as demonstrated in this case will immediately stabilize an otherwise deteriorating situation in a cost-effective way and allows patients to address the realities of financial or time constraints when transitioning to more durable porcelain restorations over a period of years.

Full-mouth rehabilitation in a completely digital workflow using partially adhesive monolithic zirconia restorations.

OBJECTIVE: This clinical case describes a completely digital workflow using current digital technologies for a full-mouth adhesive rehabilitation with ultra-translucent multilayer zirconia restorations. CLINICAL CONSIDERATIONS: A healthy 60-year-old man with abfractions on all upper and lower molars and severe tooth wear underwent a full-mouth rehabilitation with laminate veneers and partial adhesive restorations. A proper zirconia bonding protocol was realized to provide a durable bond between the ultra-translucent zirconia and the resin cement. Furthermore, the implementation of a digital workflow enables the clinician to have an effective communication during treatment planning and simplify the clinical and laboratory procedures, providing the patient with long-term esthetic treatment and functional results. CONCLUSION: The implementation of a completely digital workflow and the use of ultra-translucent multilayer zirconia for indirect adhesive restorations can be an alternative with simplified and predictable procedures for patients with dental wear and teeth discolorations. CLINICAL SIGNIFICANCE: The digital workflow described is intended to facilitate the planning and execution of a full-mouth adhesive rehabilitation and demonstrates to clinicians a reliable zirconia bonding concept for minimally invasive anterior and posterior restorations.
