Analysis of implant/abutment marginal fitting

Brazilian Dental Science, 2010
O índice de sucesso dos implantes osseointegrados gira em torno de 90%. Apesar de se conhecer bem os mecanismos da osseointegração ainda ocorrem falhas nos sistemas de implantes. Pesquisas recentes atribuem essas falhas, principalmente, à reabilitação protética do paciente. O desajuste entre a base do implante e o pilar protético e a falta de adaptação

Characterization of Defect Distribution in an Additively Manufactured AlSi10Mg as a Function of Processing Parameters and Correlations with Extreme Value Statistics

Advanced Engineering Materials, EarlyView.
Predicting extreme defects in additive manufacturing remains a key challenge limiting its structural reliability. This study proposes a statistical framework that integrates Extreme Value Theory with advanced process indicators to explore defect–process relationships and improve the estimation of critical defect sizes. The approach provides a basis for
