Analysis of stress distribution on the bone around an implant placed in the anterior maxilla using three different abutment angulations by means of finite element analysis
Aim: the aim of the study was to study the effect of stress distribution on the bone around an implant using angled abutments by means of finite element analysis in the anterior maxillary region. Materials and Methods: A three-dimensional (3D) model of the of patient's maxilla of right central...

Materials and Methods: A three-dimensional (3D) model of the of patient's maxilla of right central incisor: tooth, bone, crown, implant, and abutment system were used in this study.

The magnitude of stresses increased as the angulations increased.
