Effect of different abutment materials on stress distribution in peripheral bone and dental implant system

Abstract

In this study, the effect of different abutment materials on the stress distribution in bone tissue around the dental implant was investigated using ANSYS packet program based on finite element method. the study aims to examine the stresses, strains and deformations that will occur in the bone, dental implants and abutments with the replacement of abutment materials on the titanium dental implant. Modeling has been prepared in Solidworks program. Titanium was chosen as the dental implant material. Abutment materials were selected as titanium, zirconium, chrome-cobalt and polyetheretherketone. After modeling, necessary load was applied to the abutments and analyzed. This process was repeated for each abutment material. As a result of the analyzes, the stresses, strains and deformations that occurred in the bone, dental implants and abutments were combined into tables. in the conclusion, the differences between the abutment materials were evaluated. Generally, it was found that the lowest values were obtained in the group that chrome-cobalt was used as an abutment material. Therefore, chrome-cobalt can be preferred as an abutment material among all tested materials.
