Abstract(s)
As próteses parciais removíveis esqueléticas devem seguir um processo de conceção e fabrico rigoroso, respeitando os princípios fundamentais de Roach, que incluem retenção, estabilidade e suporte. Neste estudo, abordamos os retentores metálicos, que devem garantir uma conceção técnica irrepreensível em laboratório, e a importância da escolha adequada dos dentes pilares que suportam esses retentores, especialmente quando a condição periodontal está comprometida.
A preservação de uma condição periodontal estável é essencial para evitar cargas excessivas que podem comprometer a durabilidade e funcionalidade da prótese e aumentar a mobilidade do dente. Simultaneamente, é necessário garantir a eficácia protética, assegurando o respeito pelos princípios fundamentais, com o objetivo de garantir a perenidade do espaço dento-protético.
Este estudo analisa as forças e restrições aplicadas aos dentes pilares e discute os métodos utilizados para a pesquisa científica. Inclui também uma revisão dos princípios fundamentais de conceção protética, os materiais e métodos empregados, a avaliação periodontal dos dentes pilares, os critérios de seleção dos ganchos e uma análise comparativa dos diferentes tipos de ganchos utilizados.
Por fim, é apresentado um caso clínico de prótese parcial removível esquelética, no qual um dos pilares é um dente "isolado" dentro da arcada dentária. Este estudo destaca as problemáticas mencionadas e analisa a condição estrutural e periodontal deste dente, considerando diferentes parâmetros para determinar a melhor escolha entre os tipos de ganchos mais adequados à configuração clínica apresentada.
Skeletal removable partial dentures must follow a rigorous design and manufacturing process, adhering to Roach’s fundamental principles, which include retention, stability, and support. This study specifically addresses metallic retainers, which must ensure impeccable technical design in the laboratory, and the importance of selecting the appropriate abutment teeth to support these retainers, especially when periodontal conditions are compromised. Maintaining stable periodontal conditions is crucial to prevent excessive loads that may compromise prosthetic durability and functionality and increase tooth mobility. At the same time, ensuring good prosthetic effectiveness by adhering to fundamental principles is necessary to guarantee the longevity of the denture-prosthetic space. This study explores the forces and constraints exerted on abutment teeth and discusses the methodologies used in scientific research. It also includes a review of key principles in prosthetic design, materials and methods used, periodontal evaluation of abutment teeth, selection criteria for clasps, and a comparative analysis of different clasp types. Finally, a clinical case of a skeletal removable partial denture is presented, in which one of the abutment teeth is an “isolated” tooth within the dental arch. This study highlights the previously mentioned concerns and examines the structural and periodontal condition of this tooth, taking into account various parameters to determine the best candidate among the different clasp types most suited to the clinical configuration presented.
