The purpose of this study was to investigate the effects of composite resin restorations on the stress distribution of notch shaped noncarious cervical lesion using three-dimensional (3D) finite element analysis (FEA). Extracted maxillary second premolar was scanned serially with Micro-CT (SkyScan1072; SkyScan, Aartselaar, Belgium). The 3D images were(More)
The objective of this study was to investigate the effects of various occlusal loads on the stress distribution of the buccal cervical region of a normal maxillary second premolar, using a three dimensional finite element analysis (3D FEA). After 3D FE modeling of maxillary second premolar, a static load of 500N of three load cases was applied. Stress(More)
Noncarious cervical lesions (NCCLs), characterized by the loss of dental hard tissue at the cemento-enamel junction (CEJ) in the absence of caries, are conditions commonly encountered in dental practice. These defects can occur on facial, lingual and/or interproximal surfaces. Effects of occlusal load on the stress distribution of four cavity configurations(More)
