Biomechanics of noncarious cervical lesions

Abstract

Noncarious cervical lesions (NCCLs) restoration represents a unique clinical situation due to their multifactorial etiology. Though the mechanical theory of cervical lesions formation is widely accepted, its mechanism is not fully understood. The incidence of NCCL refers to the facial and oral aspects of the teeth. Finite Elements Method (FEM) were drawn up, applied with various occlusal forces and analyzed in order to observe the stress distribution. The standard biomechanical unit involves restorative material, tooth structure and interface between the restoration and tooth. The purpose of this study was to examine the NCCL formation caused by occlusal forces and the behavior of restored and unrestored lesions.
