A fracture mechanics approach to describe the propagation of abfractions
2011 IEEE 37th Annual Northeast Bioengineering Conference (NEBEC), 2011Abfrations (non-carious cervical lesions in teeth) are a severe problem in dental health care. Abfractions cause sensitivity to heat and cold causing discomfort and can ultimately lead to tooth failure. Currently, there is little understanding of the mechanisms of abfraction formation and propagation.

No carious cervical lesions: abfraction.
Journal of international oral health : JIOH, 2013Abfraction or Theory of Abfraction is a theory explaining the non-carious cervical lesions (NCCL). It suggests that they are caused by flexural forces, usually from cyclic loading; the enamel, especially at the cementoenamel junction (CEJ), undergoes this pattern of destruction by separating the enamel rods.

Restoration of abfracted lesions.
Compendium (Newtown, Pa.), 1995This article discusses the latest clinical findings regarding the cause of cervical lesions. Certain preparation and bonding techniques are recommended for restoring these abfractures. In particular, the composite restoratives are explained and a guide is provided for choosing the most suitable materials.

Aetiology of abfraction lesions.
The New Zealand dental journal, 2002The aetiology of abfraction lesions is complex. Most evidence indicates that physical loading forces are a major contributing factor, although they are unlikely to be entirely responsible. Intraoral chemical influences and toothbrush abrasion, combined with the dynamics of inter-occlusal activity such as chewing, swallowing, and parafunction, lead to ...

Abfractions: A New Classification of Hard Tissue Lesions of Teeth
Journal of Esthetic and Restorative Dentistry, 1991Due to the stresses resulting from biomechanical loading forces exerted on the teeth (static, as in swallowing and clenching or cyclic, as in chewing), both enamel and dentin can chip or break away. This loss of tooth substance, which shall be termed Abfraction, is dependent on the magnitude, duration, direction, frequency, and location of the forces ...

A review of the biomechanics of abfraction.
The European journal of prosthodontics and restorative dentistry, 2001Loss of tooth substance in the cervical region is usually attributed to abrasion or erosion. However, the role of occlusal loading is becoming increasingly prominent. It is suggested that high occlusal loads result in large stress concentrations in the cervical region of the teeth.

An assessment of stress analyses in the theory of abfraction.
Bio-medical materials and engineering, 2005Wedged-shaped lesions at the cemento-enamel junction of teeth have been attributed primarily to biomechanical loading forces that cause flexure and failure of enamel and dentin. This theory, termed abfraction, remains controversial. This review examined studies on mechanical properties of enamel and dentin and studies on bite forces and mastication as ...

Noncarious cervical lesions and abfractions: a re-evaluation.
Journal of the American Dental Association (1939), 2003The concept of abfraction is controversial. The authors present the fundamental basis of abfraction and review studies that describe the condition.The authors used data on masticatory forces, enamel and dentin properties, as well as stress studies related to abfraction, for background information. They also analyzed the genesis of the abfraction theory,
