Metal Posts and the Effect of Material–Shape Combination on the Mechanical Behavior of Endodontically Treated Anterior Teeth
Abstract
:1. Introduction
2. Materials and Methods
2.1. Post Design
- Post A1 (200 GPa, conical-tapered shape);
- Post A2 (110 GPa, conical-tapered shape);
- Post B1 (200 GPa, conical-cylindrical shape);
- Post B2 (110 GPa, conical-cylindrical shape).
2.2. Solid Model Generation
2.3. Finite Element Analysis
- Model A1 (a tooth with Post A1);
- Model A2 (a tooth with Post A2);
- Model B1 (a tooth with Post B1);
- Model B2 (a tooth with Post B2).
3. Results and Discussion
4. Conclusions
- FE analysis provided further insight into the effect of the material–shape combination of metal posts on the mechanical behavior of endodontically treated anterior teeth through varying material and shape.
- The possibility to tailor the stiffness and, hence, the stress distribution through an appropriate material–shape combination was demonstrated for metal posts.
- Post B2 (110 GPa, conical-cylindrical shape) provides better stress distribution as compared to the other analyzed posts.
