Passividade da estrutura metálica para próteses fixas implanto-suportadas
Abstract
Em virtude da freqüência cada vez maior de reabilitações implanto-suportadas, e de que esta modalidade de tratamento vem se mostrando extremamente eficaz na resolução de várias situações clínicas, foi realizada esta revisão literária com o objetivo de ressaltar questões relacionadas à passividade da estrutura metálica em próteses fixas sobre implantes. São descritos aspectos e alternativas relacionadas a alterações ósseas, assim como procedimentos clínicos e laboratoriais que podem influenciar na passividade de estruturas metálicas, esta que talvez seja o fator mais importante na determinação da longevidade tanto da restauração protética quanto dos implantes.
UNITERMOS: implantes dentários; soldagem; adaptação.
SUMMARY
Regarding implant-supported rehabilitations, a treatment modality extremely effective in terms of solution of several clinical situations, this study was conducted to point out subjects related to the passivity of the metallic framework. Aspects and alternatives related to bone alterations are described, as well as clinical and laboratory procedures that can influence in the framework passivity. Perhaps passivity might be the most important factor in the determination of the longevity for both prosthetic restoration and implant.
UNITERMS: dental implants; welding; adaptation.
