NOVEL DENTAL LOCKING INTERFACE DESIGN FOR MINIMUM STRESS SHIELDING IN DENTAL IMPLANTS AND ITS VALIDATION USING FEM AND ANN

Abstract

One of the most important factors determining dental implants’ longevity and effectiveness is the connection between the abutment and the implant. This investigation focuses on studying how bone shielding is affected by the interface between dental implants and abutments. In a computer-aided design (CAD) environment, three dental implant connectors and carbon-reinforced PEEK are modeled. A comparison is made between the modern dental implant locking mechanism and the more traditional internal hexagonal and conical abutment interfaces to evaluate the former’s effectiveness. ANN is employed in the process of developing the precise modulus of the dental implant material for the human jaw. Studying the von Mises stress and deformation of dental interface materials makes it possible to discover a unique locking system that exhibits the highest von Mises stress and deformation, virtually on par with the bone. However, the carbon-reinforced PEEK composite material demonstrates high bone shielding.
