Biomechanical behavior of an implant system using polyether ether ketone bar: Finite element analysis

Aim and Objectives: This study assessed, through finite element analysis, the biomechanical behavior of an implant system using the All-on-Four®technique with nickel–chromium (M1) and polyether ether ketone (PEEK) bars (M2). Materials and Methods: Implants and components were represented in three-di...

Description
Summary:Aim and Objectives: This study assessed, through finite element analysis, the biomechanical behavior of an implant system using the All-on-Four®technique with nickel–chromium (M1) and polyether ether ketone (PEEK) bars (M2). Materials and Methods: Implants and components were represented in three-dimensional (3D) geometric models and submitted to three types of load: axial, oblique, and load on all teeth. The 3D models were exported to a computer-aided design-like software such as Solidworks 2016 (Dassault Systemes, Solidworks Corps, USA) for editing and Nonuniform Rational Basis Splines parametrization. Results: Data were analyzed according to system's areas of action: peri-implant bone, implant, intermediates, intermediates' screws, prostheses' screws, and bars. Largest peak stress was shown in M2. Conclusion: PEEK is a promising material for use in dentistry; however, further studies are necessary to evaluate its performance.
