Abstract

The aim of the study was to evaluate the vertical marginal misfit between implant and different prosthetic abutments (prefabricated and castings). Material and method: The samples were divided into three groups (n = 4): group MP – personalized abutment; group UI – UCLA with metallic base in Co-Cr; group UF – UCLA with metallic base casting in Co-Cr. The specimens were analyzed in scanning electronic microscope, where it was evaluated the vertical marginal misfit. The data were submitted to the Kruskal-Wallis and Mann-Whitney statistical tests (α = 0.05). Result: The misfit means were: PA = 1.52 (±2.1); UB = 6.15 (±2.5); UA = 6.04 (±2.9). The personalized abutment showed the smallest vertical marginal misfit when compared to the UCLA abutment with metallic base in Co-Cr before and after casting process. Conclusion: All components presented acceptable fit levels for the use clinical, despite the observed differences.

Resumo

O objetivo do estudo foi avaliar o desajuste marginal vertical entre implante e diferentes componentes protéticos (pré-fabricados e fundidos). Material e método: Foram utilizados 3 grupos (n = 4): grupo MP – componentes pré-fabricados preparáveis; grupo UI – UCLA calcináveis com base metálica em Co-Cr; grupo UF – UCLA com base metálica fundidas em Co-Cr. Os espécimes foram analisados em microscópio eletrônico de varredura, onde foi avaliado o desajuste marginal vertical. Os dados foram submetidos aos testes estatísticos de Kruskal-Wallis e Mann-Whitney (α = 0,05). Resultado: As médias de desajuste (µm) encontradas foram: MP = 1,52 (±2,1); UI = 6,15 (±2,5); UF = 6,04 (±2,9). O munhão personalizável apresentou menor desajuste marginal vertical quando comparado ao pilar UCLA com base metálica em Co-Cr antes e após processo de fundição. Conclusão: Apesar das diferenças observadas, todos os componentes apresentaram níveis de adaptação aceitáveis para utilização clínica.
