Conclusion
Literature reporting on dental implants made from PEEK demonstrate that PEEK is basically osseointegrated as biocompatible material in vivo. Further investigations are necessary to find ways to improve the biomechanical behavior to achieve a more homogenous stress distribution to the surrounding bone, which has not yet been experimentally proven. Long-term investigation...

Discussion
Referring to a 3-dimensional finite element analysis of a CFR-PEEK and a titanium implant (Table 1), the authors concluded that due to its higher stress concentrations, the CFR-PEEK implant could not be recommended.11
This deformation rate could probably be diminished by an inner stiffening of the implant, for example, by an abutment connection bolt which extends to the apical region ...

Results
The search yielded 5 articles, of which 3 were included in the review.11, 34, 35 Two articles were excluded, because they did not report on dental implants of PEEK.36, 37
Of the included articles, 2 reported on animal investigations34, 35 and 1 on an in vitro finite element study.11
The aim of the 3-dimensional finite element study was to compare the stress distribution to the peri-impl...

Introduction
Dental implants increase the quality of life for many patients with tooth loss.1 The material of choice for oral endosseous implants is pure titanium, introduced at the end of the 1960s by Branemark.2 Although implants based on titanium and titanium alloys, such as Ti-6Al-7Nb and Ti- 6Al-4V,3, 4 are well evidence-based, it was demonstrated that their use can be correl...

Abstract
The insertion of dental implants containing titanium can be associated with various complications (eg, hypersensitivity to titanium). The aim of this article is to evaluate whether there are existing studies reporting on PEEK as an alternative m...
