ABSTRACT
Background: Titanium Has Been Used Considered The Gold Standard For Dental Implants For Many Years Due To Its Superior Mechanical Properties. However, It Has Many Drawbacks Regarding Corrosion And Esthetics That Required Searching For Another Alternative. In This Study, We Aimed To Determine The Amount Of Stresses Developing In The Peri-implant Bone Under Vertical Load When Different Types Of PEEK Are Used As An Implant Material.
Materials and Methods: Four Virtual Models Of A Mandible With Two Inter-foraminal Implants Supporting An Overdenture Were Designed Using SolidWorks Software. Unilateral Vertical Load Was Applied Over The Denture Teeth And Von Misses Stresses Were Collected From The Peri-implant Bone.
Results: Von Mises Stresses In The Coronal Portion Of The Peri-implant Bone Was The Highest Around PEEK Implants And The Least Around Titanium Implants.
Conclusion: PEEK Can Be Used As An Alternative To Titanium In Dental Implants From The Mechanical Point Of View, But Further Clinical Studies Are Recommended To Test The Material Behavior Intraorally.
