Comparison between basal disk implants and basal screw implants using finite element analysis method

Abstract

Background: In recent years, implant dentistry has flourished and has become the most viable treatment for rehabilitation of edentulous jaw. Most of these implants result in post-operative discomfort along with an unpredictable success rate. To overcome these issues, basal implants emerge as a reliable option for the restoration of the edentulous maxilla or mandible. Aim: The aim of this study was to compare the mechanical properties between basal disk and basal screw type implants. Materials and Methods: This research deals with a comparison of disk and screw types of basal implants on the basis of medical and mechanical aspects. We carried out finite element analysis of two types of implants. We applied a force of 100N and observed the maximum stress and deformation developed on the basal disk and screw type of implants. Results: Stress in disk type implant was 360 MPa, while it was observed to be 136 MPa in the screw type. The total deformation of the disk implant was 1.56, while the total deformation in the screw implant was 1.28. Conclusion: Hence, we find that screw types of basal implants comparatively have lesser stress values and deformation; hence, they have greater structural integrity and have lesser chances of failure. Clinical Significance: Basal screw implants are significantly more efficient in clinical use than basal disk implants.
