Exploring the bio-mechanical behavior of PEEK and CFR-PEEK materials for dental implant applications using finite element analysis.

Purpose: This study explored the bio-mechanical properties of polyether ether ketone (PEEK) and carbon fiber reinforced-PEEK (CFR-PEEK) as potential alternatives to traditional dental implant materials, such as titanium (Ti) and zirconia (ZrO). Conventional implant materials often exhibit stress shielding leading to peri-implant bone loss and implant failure.

Study Selection: Finite element analysis using a three-dimensional computer-aided-design (3D CAD) model of the jawbone with various implant materials (titanium, zirconia, PEEK, and CFR-PEEK) incorporated was implemented to assess the effectiveness of PEEK and CFR-PEEK.
