Optimizing Class II Cavity Shape with Deep Margin Elevation via Design of Experiments and Fatigue Analysis

Abstract

The purpose of this study was to evaluate the durability of class II cavities restored with deep margin elevation procedures using numerical fatigue analysis and optimize the cavity shape via a series of parametric studies with Taguchi method and response surface method Two materials of the inlay lithium disilicate and feldspathic porcelain were tested For verifying the full process a simplified experiment was used In parametric study results the size selection of Lp and W should be more cautious In experiment results the design of cavity shape could be appropriately obtained the lowest failure risk The engineering methods could be applied to the dental field and it could also make better clinical suggestions and feedback to the dentists through scientific results
