Multifactorial Analysis of Endodontic Microsurgery Using Finite Element Models.

ABSTRACT:

Background

The present study aimed to classify the relative contributions of four biomechanical factors-the root-end filling material, the apical preparation, the root resection length, and the bone height-on the root stresses of the resected premolar.

Methods

A design of experiments approach based on a defined subset of factor combinations was conducted to calculate the influence of each factor and their interactions. Sixteen finite element models were created and analyzed using the von Mises stress criterion. The robustness of the design of experiments was evaluated with nine supplementary models.

Results

The current study showed that the factors preparation and bone height had a high influence on root stresses. However, it
