Biomechanical Effects of Titanium and Carbon Fiber Reinforced PEEK as Dental Implant Material: A Finite Element Analysis.

Purpose: The aim of this study is to examine the stresses on the peri-implant bone under occlusal forces of 30% Carbon fiber reinforced PEEK (Cfr-PEEK) and 60% Cfr-PEEK materials that can be used as an alternative to titanium dental implants by finite element analysis.

Materials And Methods: Single-tooth implants of 30% Cfr-PEEK, 60% Cfr-PEEK and titanium were modeled in each of the maxillary anterior, maxilla posterior, mandibular posterior regions. As a result of the applied vertical and oblique forces; Von Misses stress, maximum principal stress and minimum principal stress values and stress distributions in the implant, cortical bone and spongious bone in each of the models were examined.
