A new retaining method of cement-retained restoration with linguo-horizontal insertion of fiber post / 대한치과보철학회지

The retaining methods of implant prosthesis were classified into a screw-retained and a cement-retained type. A screw-retained prosthesis has many advantages, such as retrievability, preventing residual cement, while their disadvantages include the possibility of screw loosening and fracture, on the contrary advantages of cement-retained prosthesis are relatively low cost, but they are difficult to retrieve. To combine the advantages of both type, screw-cement retained prosthesis (SCRP) type have been introduced. But they still require ideal implant placement. So we introduce fiber post retained prosthesis without residual cement for preventing soft tissue trouble due to excessive cement.

Restaurações cimentadas versus parafusadas: parâmetros para seleção em prótese sobre implante / Cement-retained versus screw-retained restorations: selection parameters in implant-supported prosthesis

Com a previsibilidade e longevidade relacionadas à osseointegração, o tratamento com implantes dentários tornou-se uma realidade na clínica odontológica, proporcionando uma significativa melhora no restabelecimento da saúde bucal, da função e da estética nos tratamentos odontológicos. A fim de alcançar um sucesso mais duradouro da restauração protética, é de fundamental importância a seleção adequada do sistema de retenção da prótese sobre implante. Dessa forma, é imprescindível o conhecimento de fatores como a passividade na adaptação da restauração protética, aspectos oclusais, espaço interoclusal, requisitos estéticos, saúde dos tecidos moles peri-implantares, necessidade de manutenção, reversibilidade da restauração e fator financeiro, a fim de fornecer um embasamento científico suficiente aos cirurgiões dentistas para a escolha mais adequada do tipo de sistema de retenção nas mais variadas situações clínicas. Dessa forma, o objetivo do presente estudo foi discorrer, baseado na literatura, as vantagens, desvantagens, indicações, contra-indicações e dificuldades técnicas relacionadas a cada modalidade restauradora sobre implante (parafusada e cimentada).

With the previsibility and longevity related to the osseointegration, the treatment with dental implants became a reality in the dental clinic, providing a significant improvement in the restoration of the buccal health, of the function and of the aesthetics in the dental treatments. In order to reach a prosthetic restoration more successfull, it is very important the appropriate selection of the retention system of the implant-supported prosthesis. By this way, it is indispensable the knowledge of factors as the passivity in the prosthetic restoration adaptation, occlusal aspects, interocclusal space, aesthetic requirements, peri-implant soft tissue health, maintenance necessity, reversibility and financial factor, in order to provide a satisfactory scientific support to the dentists in the most appropriate retention system choice during the several clinical situations. In that way, the aim of the current study was to discourse, based on the literature, the advantages, disadvantages, indications, contraindications and technical difficulties related to each restoring modality implant-supported screwed and cemented.
