چکیده انگلیسی
The reliability evaluation and lifetime prediction of oral restorations for dentists have always been the major concern in the field of prosthodontics. This study introduced a new methodology for dealing with stress-strength interference and an analysis to quantify the reliability of all-ceramic crowns. The response stress was based on finite element models of all-ceramic crowns, which were constructed by reverse techniques. The method utilized in this study was a probabilistic analysis that considered the all-ceramic crown as a structural component associated with multiple factors involved in the all-ceramic system including occlusal loads and mechanical properties of porcelain. The results suggested the survival probability of all-ceramic crowns after 1, 5, 10, 15, and 20 years could be computed to be 98.89%, 98.03%, 97.50%, 97.13%, and 96.93%, respectively. Probabilistic analysis methods offer a systematic technique to incorporate and account for the nature of uncertainty in ceramic restorations and allow prediction of the reliability of all-ceramic crowns under cyclic occlusal loads with accuracy.
