2020年7月17日 · Wear facets are caused by mechanical or chemical factors that have nothing to do with tooth decay. The occurrence of these facets can be explained through processes called attrition, erosion, abrasion and abfraction.

When teeth rub against each other too much, the enamel can break down and create flat, shiny, polished surfaces on our teeth - known as wear facets. These can come in different shapes and sizes depending on the cause, but they're all caused by excessive contact between teeth.

2024年3月6日 · Officially called “non-carious lesions,” wear facets happen when your teeth rub together in various ways through ongoing use. The enamel breaks down, turning your thick, healthy surfaces into flatter, shiny teeth fronts.

2024年10月31日 · Tooth wear facets are tiny notches or abrasions on the surface of teeth, often caused by excessive grinding or clenching. Angle guided therapy, a dental technique used to correct bite misalignments, can unintentionally exacerbate …

Dental attrition is tooth wear caused by tooth to tooth contact. Well-defined wear facets appear on tooth cusps or ridges. This can be caused by several factors, including parafunctional habits such as bruxism or clenching, developmental defects, hard or rough-textured diet, and absence of posterior teeth support.

Tooth wear can be classified as attrition, erosion and abrasion. Attrition is defined as the loss of enamel, dentin, or restoration by tooth-to-tooth contact (1) (Fig. 1). Erosion is the loss of dental hard tissues by chemical action not involving bacteria (2).

2015年8月24日 · Attrition – wear on the teeth from opposing occlusal contacts on the incisal or occlusal surfaces during mandibular movement. The hallmark of attrition is the creation of flat shiny wear facets in locations where the teeth are in occlusal contact. (Figs. 1-4)

Attrition happens when teeth rub against each other excessively, resulting in shiny, smooth surfaces called wear facets. It is often associated with a condition known as bruxism, which is involuntary grinding and clenching of the teeth.

Occlusal wear of teeth due to attrition is the result of friction by functional and parafunctional activities [1]. Frictional tooth wear alters the existing occlusal plane introducing deflective occlusal interferences.

2024年11月18日 · Wear facets on teeth result from excessive tooth-to-tooth contact, acidic substances, or abrasive substances. These facets can weaken teeth, making them more susceptible to cavities and other dental issues.
