Biomechanical Effects of Digitally Constructed Subperiosteal Implants From Different Materials With Different Prosthetic Superstructures on Atrophied Maxilla: A Finite Element Analysis

What this Trial Is About

Researchers are evaluating the biomechanical effects of digitally designed subperiosteal implants made from different materials on the atrophied upper jaw bone (maxilla). These implants are considered for patients with advanced bone loss where traditional implants may not be suitable. The study aims to understand which implant material could be best suited for this condition, as there is limited evidence regarding the optimal material choice. The study compares virtual designs of subperiosteal implant frameworks made from three materials: titanium, PEEK, and PEKK. These frameworks are digitally constructed for use on the atrophied maxilla bone. A 3D image of the patient's upper jaw bone is created from a computed tomography scan and processed into a digital model. This model is used to simulate force loading between the implant parts, screws, and bone tissues to analyze biomechanical behavior. Participants will contribute by providing their computed tomography scan data that produces the 3D image of their edentulous maxilla bone. Researchers will analyze bone loss under the implants over a period of 10 to 15 years using digital simulation methods. The study is observational and does not involve direct treatment but focuses on evaluating implant framework materials and prosthetic superstructures in the digital environment. The trial includes adults aged 30 to 70 with specific bone classifications of the maxilla.
