Effect of deep margin elevation and cavity configuration on the mechanical behavior of endocrown restorations: a 3D finite element study.

ABSTRACT:

Background

Restorative procedures following endodontic treatment are crucial for preserving the functional integrity of the tooth, preventing coronal leakage, and protecting the root canal system from contamination. The present study aims to compare the effects of different marginal elevation strategies and restorative material combinations on stress distribution and fatigue life, using three-dimensional (3D) finite element analysis (FEA) of mandibular first molar models prepared with DO, MO, and MOD cavity designs.

Methods

The anatomical structure of tooth number 36 was scanned using cone beam computed tomography. Three different cavity types were then created on the tooth. In the same model, deep margin elevation (DME) was applied in single and double layers of filler mate
