The meaning of ABFRACTION is a mechanism that is postulated to explain loss of tooth enamel and dentin in the part of a tooth between the crown and root in the absence of tooth decay; also : the narrow usually V-shaped area of tooth loss caused by abfrac

It notes that causes of abfraction include excessive chewing and or biting forces such as bruxism, erosion and corrosion. It also mentions that abfraction closely resembles with abrasion, which requires a detailed comprehensive examination to differentiate the two....
Modern dental practices frequently encounter patients who exhibit various forms of wear to the dentition. The wear may present as abfraction, abrasion, attrition, and/or erosion.

A volume of 25,000 A-scans is collected in 2.5 s. All these recommend the SS-OCT method as a valuable tool for dynamic evaluation of the abfraction and attrition with remarkable potential for clinical use. 展开 关键词: Bicuspid Incisor Dental Enamel Humans Imaging, Three-Dimensional Tomography...
Many workers have suggested that abfraction lesion formation is caused by the physical overloading of enamel. However, an alternative mechanism, involving undermining of the cervical enamel along the amelodentinal junction (ADJ), may be a more realistic explanation. The aim of this study was to ...
