Abstract:

Introduction: Periodontal Disease affects 64.7 million Americans per year totaling 47.2% of the population. Symptoms include swollen, discolored, tender gums, gum recession, loose teeth, and a change in bite. Treatment options are dependent on the severity of the disease and include non-invasive measures such as scaling, rooting, and arestin treatment, as well as more invasive procedures such as surgery to eliminate bone infection, regenerate lost bone, and replace loss teeth. Purpose: The aim is to find a material and design that will optimize implant success for those with periodontal disease. Materials and Methods: Finite Element Analysis (FEA) is a technique, which is widely used to predict the performance of various dental implant designs. In this study, we are using several dental implants with same length, same diameter and screw design which is stimulated under Von-Miss stress distribution and total deformation under vertical/lateral load as compared to each implant. The research focused on the factors such as thread pitch, thread geometry, helix angle, thread depth and width as well as implant stability related to the design of dental implant success. It also involves the functional assessment osseointegration, which is defined as cascade of protein and cell apposition. Three materials were used for a platform-switched dental implant-abutment assembly, Type 1 consisted of titanium, Type 2 with powder-filled PEEK and Type 3 with Endolign. The functionally graded material (FGM) dental implants used in the project will be tailored according to the biomechanical needs of the patients with periodontal disease by adapting to hosting biomechanical tissues thus will create overall integration and stability in the restoration. Result: All types showed minimum safety factor that will optimize implant success for those with periodontal disease.
