INVESTIGATION OF STRESS-STRAIN STATE OF "RESTORATION & TOOTH" SYSTEM IN WEDGE-SHAPED DEFECTS BY COMPUTED MODELING METHOD.

Objective: The aim of this research is to study the influence of size and location of wedge-shaped defects of teeth on stress and strain state of restorative material on the basis of biomechanical analysis.

Patients And Methods: Materials and methods: Biomechanical analysis of the stress-strain state was performed on a jaw bone fragment with canine and premolar inclusion.

Results: Results: Tangential stress increase both in the adhesive layer and in restorative material with depth and width (medial-distal size) of restored wedge-shaped defects of teeth,.
