Resumo(s)
A durabilidade das restaurações dentárias representa uma preocupação constante na prática clínica, evidenciando a importância de abordagens que assegurem resultados previsíveis a longo prazo.
O aumento das exigências estéticas por parte dos doentes e o desenvolvimento de materiais dentários e técnicas de adesão tem permitido expandir o número de opções de tratamento, seguindo os princípios da medicina dentária minimamente invasiva. Entre estas opções estão os inlays, onlays e overlays.
As restaurações indiretas em dentes posteriores são tipicamente fabricadas em resina composta ou cerâmica. Estes dois materiais destacam-se de formas diferentes pelas suas propriedades mecânicas e pela capacidade de mimetizar a dentição natural, assegurando funcionalidade, estética e sendo mais conservadores que outros tratamentos como coroas dentárias.
Várias propriedades influenciam a performance de um material restaurador e são levadas em consideração antes da escolha do mesmo. Entre elas a estética, a durabilidade, dureza, flexibilidade, resistência a fratura, facilidade de reparação, custo económica e necessidades específicas do paciente.
A seleção adequada do material restaurador, associada a um correto planeamento e execução clínica, é determinante para alcançar os resultados mais previsíveis e duradouros possíveis.
O objetivo deste trabalho consiste na comparação entre inlays, onlays e overlays em cerâmica e resina composta analisando as suas vantagens, desvantagens, indicações, performance e possíveis complicações.
The durability of dental restorations represents a constant concern in modern clinical practice, highlighting the importance of approaches that ensure predictable long-term outcomes. The increased aesthetic demands of patients and the development of dental materials and bonding techniques have allowed for an expansion of treatment options, following the principles of minimally invasive dentistry. These options include inlays, onlays, and overlays. Indirect restorations in posterior teeth are typically made of composite resin or ceramic. These two materials stand out in different ways for their mechanical properties and their ability to mimic natural dentition, ensuring functionality and aesthetics, while being more conservative than other treatments such as dental crowns. Several properties influence the performance of a restorative material and are taken into consideration before selecting it. These include aesthetics, durability, hardness, flexibility, fracture resistance, ease of repair, cost-effectiveness, and specific patient needs. The appropriate selection of the restorative material, combined with proper clinical planning and execution, is crucial to achieving the most predictable and long-lasting results possible. The objective of this study is to compare ceramic and composite resin inlays, onlays, and overlays, analyzing their advantages, disadvantages, indications, performance, and potential complications.
