A conservative full-mouth ceramic rehabilitation for a severely worn dentition.

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.

Oral health care for older persons with Alzheimer's disease: considerations about treatment planning and caregiver involvement

Alzheimer's disease (AD) is a neurodegenerative and progressive disease that predominantly affects women and has no cure. Obstacles to the dental care of people with AD differ in each phase, but the dental surgeon should remember to include the caregivers, formal or informal, in the treatment. Some skills need to be considered in the planning process, and dental health indices can be very helpful for the professional to assess the patient's ability to undergo treatment and how the older person can benefit from it. The dental surgeon should evaluate each person's specific needs so that personalized oral hygiene protocols can be established. The suggested adaptations must be by the reality of the older adult with AD, the family context, and daily routine, and they must contemplate the information provided by the caregiver. In this article, we invite the dental surgeon to understand the continuum of AD to properly plan treatment, considering the individual's limitations, future perspectives, and safety, always keeping the older adult free of oral infections and comfortable with his or her oral health condition

A doença de Alzheimer (DA) é neurodegenerativa, de caráter progressivo, afeta predominantemente mulheres e até o momento não possui cura. Os obstáculos para o atendimento odontológico de pessoas com DA são diferentes em cada fase, porém em nenhuma delas o cirurgião-dentista pode esquecer de incluir os cuidadores, formais ou não, no tratamento. Algumas habilidades precisam ser consideradas no processo de planejamento, e os índices odontológicos podem ser de grande utilidade para que o profissional pondere sobre a capacidade de o paciente receber o tratamento e quanto ele pode se beneficiar dele. A avaliação das necessidades específicas para cada indivíduo deve ser conduzida pelo cirurgião-dentista, de forma que seja possível estabelecer os protocolos personalizados de higiene oral. As adaptações sugeridas devem estar de acordo com a realidade da pessoa com DA, de seu contexto familiar, de sua rotina diária, e devem contemplar as informações fornecidas pelo cuidador. O cirurgião-dentista deve compreender o continuum da DA para planejar adequadamente, considerando as limitações, as perspectivas futuras e a segurança do indivíduo, mantendo-o sempre livre de infecções e confortável com sua condição de saúde bucal, em colaboração com seus cuidadores, formais ou informais

Osteonecrosis de los maxilares asociada a drogas antirresortivas en pacientes osteoporóticos: presentación de un caso clínico / Antiresorptive drugs-related jaw osteonecrosis in osteoporotic patients: report of a clinical case

La osteoporosis se caracteriza por una masa ósea baja con deterioro de la microarquitectura del tejido que conduce a la fragilidad, lo que aumenta el riesgo de fracturas. Después de la menopausia, la deficiencia de estrógenos aumenta la exposición del tejido al ligan- do RANK, lo que resulta en un aumento de la reabsorción y pérdida ósea, que pueden provocar osteoporosis. (1) Los bifosfonatos y el denosumab son utilizados para el tratamiento de la osteoporosis debido a su capacidad anticatabólica, que reducen la remodelación previniendo la pérdida de masa ósea, disminuyendo la probabilidad de fracturas y aumentando la densidad mineral del tejido. (2) La osteonecrosis de los maxilares asociadas a drogas antirresortivas es una situación que se presenta en pacientes que consumen de manera crónica antirresortivos para el tratamiento de enfermedades como: osteoporosis, osteogénesis imperfecta, enfermedad de Paget, displasia fi- brosa, hipercalcemia maligna asociada a tratamiento oncológico (AU)

Osteoporosis is characterized by low bone mass with deterioration of the tissue microarchitec- ture leading to fragility, which increases the risk of fractures. After menopause, estrogen deficiency increases tissue exposure to the RANK ligand, resulting in increased bone loss and resorption, which can lead to osteoporosis. (1) Bisphosphonates and denosumab are used for the treatment in low concentration, due to their anticatabolic capacity, which reduce remodeling, preventing loss of bone mass and fractures besides, antiresorptives drugs increase the mineral density of the tissue. (2) Osteonecrosis of the jaw associated with antiresorptives drugs occurs in patients whose chro- nically consume these drugs for the treatment of diseases such as: osteoporosis, imperfect osteogenesis, Paget's disease, fibrous dysplasia, malignant hypercalcemia associated with oncological treatment (AU)

Comprehensive prosthodontic treatment of an elderly patient with compromised ridges: a clinical case report / Tratamiento prostodóntico integral de un paciente anciano con proceso alveolar comprometido: informe de un caso clínico

Introduction: The objective of a complete denture prosthesis is restoring aesthetics, comfort, and function by the replacement of missing dental and alveolar structures employing a stable prosthesis. Case Report: Many conditions can complicate the treatment plan and fabrication of a complete denture prosthesis. Complete denture fabrication in clinically compromised conditions is a challenging task for the dentist. In this clinical report, we present comprehensive management of a patient with denture-induced hyperplasia, flabby ridge, and severely resorbed edentulous ridge. The three part strategy for management of the above-mentioned challenges can provide high-quality complete dentures, based on recognized prosthodontic principles. This first part will discuss the management of denture induced hyperplasia by elimination of the inflammation and excision of the lesion. Part two will cover management of the flabby ridge using a modified window technique for the impression of maxillary flabby tissues for an improved and controlled application of the impression material that is usually obtainable in dental practice. Part three highlights the rehabilitation procedure of the resorbed mandibular ridge using a functional impression technique with minimum soft tissue displacement and neutral zone arrangement of teeth to improve stability of the denture. Conclusion: rehabilitation of a patient with denture induced hyperplasia, flabby ridge, and severely resorbed edentulous ridges was successful.

Conclusion: La rehabilitación de un paciente con hiperplasia inducida por dentaduras postizas, cresta flácida y reabsorbida fue exitosa.

In-vivo-wear in composite and ceramic full mouth rehabilitations over 3 years.

The aim of this study was to quantify and to compare the wear rates of premolar (PM) and molar (M) restorations of lithium disilicate ceramic (LS2) and an experimental CAD/CAM polymer (COMP) in cases of complex rehabilitations with changes in vertical dimension of occlusion (VDO). Twelve patients with severe tooth wear underwent prosthetic rehabilitation, restoring the VDO with antagonistic occlusal coverage restorations either out of LS2 (n = 6 patients, n = 16 posterior restorations/patient; N = 96 restorations/year) or COMP (n = 6 patients; n = 16 posterior restorations/patient; N = 96 restorations/year). Data was obtained by digitalization of plaster casts with a laboratory scanner at annual recalls (350 ± 86 days; 755 ± 92 days; 1102 ± 97 days). Each annual recall dataset of premolar and molar restorations (N = 192) was overlaid individually with the corresponding baseline dataset using an iterative best-fit method. Mean vertical loss of the occlusal contact areas (OCAs) was calculated for each restoration and recall time. For LS2 restorations, the mean wear rate per month over 1 year was 7.5 ± 3.4 µm (PM), 7.8 ± 2.0 µm (M), over 2 years 3.8 ± 1.6 µm (PM), 4.4 ± 1.5 µm (M), over 3 years 2.8 ± 1.3 µm (PM), 3.4 ± 1.7 µm (M). For COMP restorations, the mean wear rate per month over 1 year was 15.5 ± 8.9 µm (PM), 28.5 ± 20.2 µm (M), over 2 years 9.2 ± 5.9 µm (PM), 16.7 ± 14.9 µm (M), over 3 years 8.6 ± 5.3 µm (PM), 9.5 ± 8.0 µm (M). Three COMP restorations fractured after two years and therefore were not considered in the 3-year results. The wear rates in the LS2 group showed significant differences between premolars and molars restorations (p = 0.041; p = 0.023; p = 0.045). The wear rates in COMP group differed significantly between premolars and molars only in the first two years (p < 0.0001; p = 0.007). COMP restorations show much higher wear rates compared to LS2. The presented results suggest that with increasing time in situ, the monthly wear rates for both materials decreased over time. On the basis of this limited dataset, both LS2 and COMP restorations show reasonable clinical wear rates after 3 years follow-up. Wear of COMP restorations was higher, however prosthodontic treatment was less invasive. LS2 showed less wear, yet tooth preparation was necessary. Clinicians should balance well between necessary preparation invasiveness and long-term occlusal stability in patients with worn dentitions.

Manejo e integración estomatológica del paciente pediátrico con trastorno de Asperger / Management and dental integration of the pediatric patient with Asperger disorder

Trastorno neurológico enmarcado dentro de los trastornos de espectro autista (TEA) cuyas manifestaciones se reflejan en los ámbitos de la comunicación, interacción e imaginación social. Se clasifica en el manual diagnóstico y estadístico de trastornos mentales (DSM IV), se caracteriza por un mayor o menor grado de deterioro en las habilidades de lenguaje y comunicación, así como patrones repetitivos o restrictivos de pensamiento y comportamiento. El síntoma más distintivo es el interés obsesivo en un solo objeto o tema y la exclusión de cualquier otro pero siempre conservando habilidades de lenguaje. El pronóstico es bueno, debido a la compensación cognitiva, el enfoque repetitivo y restrictivo a actividades humanas productivas o generadoras de deferencias particulares, aunque no hay tratamiento específico, sino más bien interdisciplinario e individualizado, éste consiste en manejar los síntomas conductuales y la comorbilidad de forma independiente ya sea farmacológica o intervencionista. Paciente masculino de cinco años de edad, con un peso de 26 kg, cuadro de inmunizaciones completas, previamente diagnosticado con trastorno de Asperger (2015); caries dental de diversos grados, manejo estomatológico para su rehabilitación. El objetivo de este reporte es dar a conocer los cuidados para el tratamiento dental en pacientes con este trastorno (AU)

Neurological disorder known as autism spectrum disorders (ASD) whose main manifestations are reflected in the areas of communication, interaction and social imagination. It was first classified in the Diagnostic and Statistical Manual of Mental Disorders (DSM lV), characterized by a greater or lesser degree of deterioration in language and communication skills, as well as repetitive patterns or restrictive of thought and behavior. The most distinctive symptom is obsessive interest in a single object or topic and the exclusion of any other, but always retaining language skills. The prognosis is good in most of the cases, due to the cognitive compensation, the repetitive and restrictive approach to productive or deferential human activities, although there is no specific treatment, but rather interdisciplinary and individualized, this consists of managing behavioral symptoms and comorbidity independently either pharmacologically or interventionally. Male patient with five years old and weight of 26 kg, complete immunization chart, previously diagnosed with Asperger's disorder (2015); with dental caries of various degrees implementing dental management. The objective of this report is to make aware of the care and behavior management for dental treatment in patients with this Disorder (AU)

Objetivo: avaliar a previsibilidade das reabilitações de maxilas edêntulas através da técnica all-on-four, mensurada pelas tensões sobre implantes em estudos laboratoriais e sobrevida de próteses, perda óssea marginal e sucesso dos implantes em estudos clínicos. Revisão de literatura: foi executada uma busca na literatura nas bases de dados Lilacs, SciELO e PubMed/Medline, utilizando termos relacionados ao tema, sem restrição temporal e adaptados para cada base. As buscas foram realizadas por um único examinador no período de setembro a novembro de 2019. Após a leitura crítica dos 21 artigos selecionados, constata-se que existem vários estudos com muitos delineamentos que avaliaram a previsibilidade mensurada de várias formas. Considerações finais: diante das evidências científicas encontradas, a reabilitação de maxilas edêntulas com a técnica all-on-four demonstra ser previsível e estável. Estudos retrospectivos, prospectivos e revisões sistemáticas relatam altos índices de sucesso, baixa perda óssea marginal, embasando o uso da técnica all-on-four na odontologia.(AU)

Objective: to assess the predictability of edentulous maxillary rehabilitation using the all-on-four technique, measured by tensions over implants in laboratory studies and prosthetic survival, marginal bone loss and implant success in clinical studies. Literature Review: A literature search was performed in the Lilacs, SciELO and PubMed/ Medline databases, using terms related to the theme, without time restriction and adapted for each base. The searches were carried out by a single examiner from September to November 2019. After a critical reading of the 21 selected articles, it appears that there are several studies with many designs that evaluated the predictability measured in various ways. Final considerations: In view of the scientific evidence found, the rehabilitation of edentulous jaws with the all-on-four technique proves to be predictable and stable. Retrospective, prospective studies and systematic reviews report high success rates, low marginal bone loss, basing the use of the all-on-four technique in dentistry.(AU)

Tratamiento de la periimplantitis. Explantación atraumática y nuevo tratamiento con implantes. Reversibilidad de la oseointegración / Treatment of peri-implantitis. Atraumatic explantation and new treatment with implants. Reversibility of osseointegration

La periimplantitis se define como la patología inflamatoria e irreversible que afecta al hueso periimplantario y le hace perder soporte y función al implante según la definición del European Workshop on Periodontology (EWOP). La prevalencia estimada de la periimplantitis es de 28 a 77%. Los diferentes protocolos de abordaje de la periimplantitis nos ofrecen diversas posibilidades: destoxificación de la superficie y regeneración, limpieza mecánica y resección del tejido inflamado, extracción del implante, entre otros. El principal problema de los tratamientos regenerativos es limpiar y desintoxicar correctamente la superficie del implante expuesto, ya que al tratarse de superficies generalmente muy rugosas, las bacterias del medio bucal las colonizan con mucha facilidad y es prácticamente imposible eliminar por completo el biofilm. El protocolo de tratamiento para la periimplantitis se basa en un algoritmo de tratamiento, en el que se retiran los implantes gravemente afectados por periimplantitis de forma atraumática, lo cual garantiza la conservación del lecho al 100% al no retirarse volumen óseo, y cuándo deben utilizarse las trefinas, pues las que se utilizan en el protocolo únicamente rompen la unión ósea de los primeros milímetros sin retirarlo. En el siguiente caso clínico mostramos el retratamiento de un caso de periimplantitis en el que se ha realizado una nueva rehabilitación implantosoportada (AU)

Periimplantitis is defined as the inflammatory and irreversible pathology that affects the peri-implantary bone and causes it to lose support and function to the implant as defined by the European Workshop on Periodontology (EWOP). The estimated prevalence of periimplantitis figures ranging from 28 to 77%. The different protocols for approaching periimplantitis offer different possibilities: detoxification of the surface and re-generation, mechanical cleaning and resection of inflamed tissue and extraction of the implant mainly. The main problem with regenerative treatments is to correctly clean and detoxify the surface of the exposed implant, since as these are generally highly rough surfaces, bacteria in the oral environment colonise them very easily and it is practically impossible to completely eliminate the biofilm. This treatment algorithm, in which implants severely affected by periimplantitis are removed atraumatically, guarantees the conservation of the bed at 100% since no bone volume is removed and trephines must be used, since those used in the protocol only break the bone union of the first few millimetres, without removing it. In the following clinical case, we show the re-treatment of a case of peri-implantitis where a new implant-supported rehabilitation has been performed (AU)

Full Mouth Rehabilitation of Two Siblings with Dentinogenesis Imperfecta Type II Using Different Treatment Modalities.

BACKGROUND: Dentinogenesis imperfecta (DGI) is a complex anomaly, not only by its structure but by treatment approach. The treatment protocol depends on the severity, behavior, and the age of the patient. CASE DESCRIPTION: This paper presents two siblings' cases of DGI type II (DGI-II) with different treatment based on the patient's clinical severity, behavior, and age (mixed versus primary dentition). The first case involves a patient in the primary dentition with severe attrition leading to a reduction in the vertical dimension of occlusion (VDO) treated by the fabrication of complete overlay dentures. The second case involves a patient in the early mixed dentition treated with restorations and extractions. CONCLUSION: Full mouth rehabilitation in the two patients dramatically improves function, aesthetics, and proved to be a significant psychological boost to the patient's well-being. PRACTICAL IMPLICATIONS: Early diagnosis and a multidisciplinary approach for patients with DGI to preserve the remaining teeth and rehabilitation for their function and aesthetics are essential for obtaining a favorable prognosis.

Reabilitação de maxila atrófica com implantes zigomáticos: relato de caso / Rehabilitation of atrophic maxilla with zygomatic implants: case report

Introdução: maxilas severamente atrofiadas representam um desafio às reabilitações implantossuportadas. A reconstrução maxilar com enxertos ósseos para permitir a reabilitação com implantes osseointegrados é um tratamento com boa previsibilidade e alto índice de sucesso. No entanto, a morbidade causada pela necessidade de regiões doadoras e grande quantidade de osso dificulta a aceitação dos pacientes, podendo, inclusive, ser contraindicada dependendo da condição sistêmica. Objetivos: revisar a literatura, discutir as indicações, as complicações, a previsibilidade das reabilitações com implantes zigomáticos, assim como relatar um caso. Relato de caso: os implantes zigomáticos surgiram como uma alternativa para a reabilitação de pacientes maxilectomizados, decorrente da exérese de tumores, perdas ósseas decorrentes de infecções ou traumas, e casos de atrofia óssea severa, como abordado no caso em questão, em que a paciente apresentava edentulismo total em maxila e não gostaria mais de utilizar a prótese convencional, optando pela prótese sobre implante. Considerações finais: a reabilitação com implantes zigomáticos pode apresentar complicações, como o mau posicionamento dos implantes, comprometendo a reabilitação; todavia, apesar das restrições da técnica, a literatura mostra que os implantes zigomáticos, quando bem indicados, representam uma boa alternativa para a reabilitação de maxilas severamente atrofiadas.(AU)

Introduction: severely atrophied jaws pose a challenge to implant-supported rehabilitations. Maxillary reconstruction with bone graft to allow rehabilitation with implants is a treatment with good predictability and high success rate. However, a morbidity is the disease of the donor regions and the greater amount of bone hinders the acceptance of the patients; including, to be contraindicated depending on the systemic condition. Objectives: this article is a review of the literature, such as the indications, complications, predictability of rehabilitations with zygomatic implants, as well as a case report. Case report: the zygomatic implants appeared as an alternative for the rehabilitation of maxilectomized patients, due to the excision of tumors, bone losses due to infections or trauma and cases of severe bone atrophy, as approached in the case in question, in which the patient had total maxillary edentulism and would no longer like to use the conventional prosthesis, opting for the implant prosthesis. Final considerations: rehabilitation with zygomatic implants may present complications, such as poor placement of implants, compromising rehabilitation; however, despite the limitations of the technique, the literature shows that zygomatic implants, when well indicated, represent a good alternative for the rehabilitation of severely atrophied maxilla.(AU)

Oral rehabilitation with dental implants in patients with recessive dystrophic epidermolysis bullosa: A retrospective study with 2-15 years of follow-up

BACKGROUND: Epidermolysis bullosa (EB) comprises a group of hereditary disorders characterized by mechanical fragility of the skin and mucous membranes, with the development of blisters and vesicles in response to minimum tissue friction. Recessive dystrophic epidermolysis bullosa (RDEB) with generalized involvement is the most common subtype in the oral cavity. The present study was carried out to investigate dental implant survival, peri-implant tissue condition, patient satisfaction, and the impact of treatment upon the quality of life of patients with RDEB rehabilitated with implants and full-arch implant-supported prostheses. MATERIAL AND METHODS: Thirteen patients with RDEB underwent dental implant treatment between September 2005 and December 2016. A retrospective study was made to analyze implant survival, peri-implant tissue health and patient satisfaction. RESULTS: A total of 80 implants were placed (42 in the maxilla and 38 in the mandible) in 13 patients between 20-52 years of age and diagnosed with RDEB. All the implants were rehabilitated on a deferred basis with 20 full-arch prostheses. Fifteen fixed prostheses and 5 implant-supported overdentures were placed. The implant survival rate was 97.5% after a mean follow-up of 7.5 years after prosthetic loading. Fifty percent of the implants showed mucositis at the time of evaluation. Probing depth was maintained at 1-3 mm in 96.2% of the implants, and bleeding upon probing was observed in 67.5% of the implants. There was a high prevalence of bacterial plaque (85%). CONCLUSIONS: The treatment of edentulous patients with RDEB by means of implants and implant-supported prostheses is predictable as evidenced by the high success rate, and improves patient self-esteem and quality of life

(2011). At the end of the treatment, a new photographic record was taken, then the vertical dimension measurement (distance between upper lip) and horizontal (distance between corners right/left), using the program Corel Draw X3. RESULTS: The mean mouth opening increased from the initial evaluation to the final evaluation, increasing 5.1 mm in the horizontal direction (67.3 mm to 72.4 mm) and 13.9 mm in the vertical direction (from 32.7 mm to 46.6 mm). These differences are significant for the evaluations (p<0.05). CONCLUSION: The use of oral orthosis associated with speech therapy proved to be effective as another tool in the prevention of microstomia.

Contemporary full-mouth rehabilitation using a digital smile design in combination with conventional and computer-aided design/manufacturing restorative materials in a patient with bruxism: A case report.

RATIONALE: Full-mouth rehabilitation of patients with bruxism and severely worn dentition poses a great challenge to clinicians. Several treatment planning methods and restorative materials are used to treat tooth wear in modern dentistry. Clinicians should be able to select the most suitable treatment planning methods and materials for individual patients depending on their specific situation. PATIENT CONCERNS: A 47-year-old male was referred for evaluation of a severely worn dentition. DIAGNOSES: Clinical and radiographic evaluation revealed tooth wear in the entire dentition. The interocclusal distance at rest was 4 mm, and the patient had a parafunctional habit of bruxism. INTERVENTIONS: A digital smile design was used to formulate a treatment plan. Full-mouth rehabilitation was performed using a combination of conventional and digital materials and methods. OUTCOMES: The full-mouth restoration showed satisfactory functions and esthetics. No complications were observed in the restorations, supporting tissues, and temporomandibular joints during 2-year follow-up. LESSONS: In clinical practice, it is important to determine the optimal combination of the available methods for treatment planning. This case report details the formulation of a unique treatment plan for the dental rehabilitation of a severely worn out dentition, which is considered challenging due to the limitations imposed by biological tissues and restorative materials. The use of conventional and digital tools for treatment planning, patient education, and treatment execution was demonstrated.

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.
