Do implants made of polyetheretherketone and its composites have reduced stress shielding effects compared to other dental implant materials? A systematic review

Abstract

Purpose: The present systematic review was executed to evaluate the stress shielding effect of PEEK and its composite dental implants as compared to other implant (titanium and zirconia) materials in peri-implant bone.

Materials and method: The comprehensive online literature search was conducted on PubMed, Google Scholar, and Web of Science from January 2011 to January 2023. A total of 43 in vitro studies were identified related to the raised question. In all, 34 studies were excluded as they included in vitro studies focusing on stress distribution in prosthesis framework, abutments, crown, and on biological properties such as cell adhesion, etc. Only eight studies after full-text screening were included in the present systematic review.

Results: The data extracted from included studies showed that PEEK and its composite materials, have a less stress shielding effect due to their low modulus of elasticity resulting in higher stress concentration and strain in the peri-implant bone as compared to titanium and zirconia implant materials.

Conclusion: The PEEK and its composites can be used as an alternative material in the esthetic region and in those who have an allergy to metal implants. However, due to the low elastic modulus of PEEK, a homogenous stress distribution is not observed along the entire length of the implant. Further studies are required to improve the composition of PEEK material so that a homogenous reduction of stress shielding effect along the whole length of a dental implant can be achieved.
