Assessment of occlusal force distribution using T-scan pre-operative and post-cementation of full metal crowns fabricated by conventional and direct metal laser sintered (DMLS) technique- A split-mouth randomized clinical study

Abstract

ABSTRACT STATEMENT OF PROBLEM A healthy and functional masticatory system depends on the physiological repair of occlusion. Surfaces of contact between occluding teeth dictate the area accessible to shearing food with each chewing cycle, and a variety of parameters, including bite forc e, occlusal contact area, and the number of functioning teeth, may affect masticatory efficiency. The distribution of occlusal forces may differ in individuals who have had prosthetic rehabilitation using crowns and bridges. To safeguard the stomatognathic system, these forces must be assessed and removed in order to produce a harmonic occlusal force distribution. To demonstrate that both DMLS and traditionally produced crowns are clinically acceptable, comparative investigations on their accuracy and prec ision have been conducted. Shimstock foils and articulating sheets are utilised to document occlusal differences. But only qualitative evaluation is possible. By transforming qualitative data into quantitative characteristics and digitally presenting them, the T SCAN system accurately captures and evaluates the period of time sequence and force magnitude of the occlusal interactions in order to quantify the occlusal forces. Hence, the present study is undertaken to assess the occlusal force distribution by using T- scan pre-operative and post-cementation of metal crown fabricated by conventional and DMLS techniques - A split-mouth randomized clinical study. AIM Assessment of occlusal force distribution using T-scan pre-operative and post-cementation of full metal crowns fabricated by conventional and DMLS techniques.
