Investigation of Temperature and Stress Distributions in a Dental Implant Prosthesis
Abstract
Todays, the increasing success rates, and intensity of use of implant applications have attracted attention in the field of dentistry to dental implants. In this study, the temperature and stress distribution in a dental implant was modeled in three dimensions using the commercial software Ansys, which uses the finite element method. The changes in the implant prosthesis were investigated by applying a 100N load to the model and a temperature of 45o C and 10o C, respectively. The temperature input condition was accepted as the temperature of freshly taken food/beverage from the stove for the highest temperature and the temperature of freshly taken out of the refrigerator for the lowest temperature. As a result of the analyzes (Fluid Flow), it was observed that the implant prosthesis didn’t conduct heat to the tooth root at 45o C and 10o C. As a result of the von Mises stress distribution and total deformation analysis under a load of 100 N, it was determined that the tensile and compressive strength was good (48.17 MPa), and most of the applied load was supported by the artificial tooth crown. The chewing force applied due to its structure from the tooth geometry causes non-homogeneous stress distribution in all axes. Thus, it reveals that mechanical compatibility is of great importance as well as biocompatibility. Titanium alloys (Ti-6Al-4V), which are frequently used in tooth crowns and tooth roots, cause differentiation in bone structure together with the formation of a protective oxide layer. Considering the loss of bone volume and resorption diseases, especially during the osteoporosis/menopause, it is possible that a problem may occur at the implant-bone interface.
