This study evaluated the polymerization shrinkage stress of three tooth preparation designs for indirect ceramic overlay by finite element analysis: isthmus preparation (IST); without isthmus preparation (wIST); and ...

Objectives: The purpose of this in vitro study was to evaluate the coronal marginal leakage after post space preparation in teeth filled with three different sealers, according to the period between the root canal filling ...

Purpose: To evaluate the influence of the geometry and design of prosthetic crown preparations on stress distribution in compression tests, using finite element analysis (FEA). Materials and Methods: Six combinations of ...
