Abfraction is a theoretical concept explaining a loss of tooth structure not caused by tooth decay (non-carious cervical lesions). It is suggested that these lesions. Multiple factors are seen as contributing to the development of noncarious cervical lesions (NCCLs). The term abfraction is applied to these lesions in relation to. Evidence supports that abfraction lesions, as any NCCLs, have a multifactorial etiology. Particularly, the cervical wear of abfraction can occur.

As a result of the reported associations between occlusal stress and abfraction lesions, occlusal adjustment has been proposed as an alternative treatment to prevent the initiation and progression of these lesions and to minimize failure of cervical leslons.

Periapical, mandibular and maxillary hard tissues — Bones of jaws. One of the most prevalent theories is called “the theory of non-carious cervical lesions” which suggests that tooth flexion, occurring due to occlusion factors, impacts on the vulnerable area near the cementoenamel junction.

The defense mechanisms activated in teeth as a result of wear include the formation of reactionary and reparative dentin and the obstruction of exposed dentinal tubules by mineral deposits.


The present review focuses on the etiology and all available treatment plan strategies of non-carious cervical lesions. The aetiology of the non-carious cervical lesion. The various clinical manifestations lssions abfraction appear to be dependent on the type and severity of the etiological factors involved. A critical review of non-carious cervical wear lesions and the role of abfraction, erosion, and abrasion. An appliance or night guard can protect the teeth from further wear.

Paryag A, Rafeek R. Preservation and Restoration of Tooth Structure. The restoration must recreate not only the contour of the tooth crown but also the contour of the lost CEJ at lesios root portion. Moreover, very few clinical studies have not provided enough evidence on the relation between Abfraction lesions and occlusal stresses [ 27 – 29 ]. If you have an NCCL, they will monitor it and provide suggestions for controlling the occasional sensitivity that the lesion may cause.

Nevertheless, there is no abfractuon that restorative treatment of NCCLs is effective in impeding further development of the lesions, and therefore, restorations cannot be used as a preventive measure to stop lesion progression.

Abfaction of Abfraction Lesions The lesions have been attributed to mechanical stress from chewing function or teeth grinding. What Causes Dental Abfractions? The retention of the cement is also an important criterion while planning for a restorative NCCL procedure.

Dentinal hypersensitivity is a response to stimuli caused by short, sharp pain. Arrow shows the second upper premolar with the typical lesion. Generally, physiological cervical wear is a chronic and slow process. Marked variations exist in dental practice concerning the diagnosis and management of these lesions.

In an era of personalized dentistry, patient risk factors for NCCLs must be identified and addressed before any treatment is performed. Abfraction is a theoretical concept explaining a loss of tooth structure not caused by tooth decay non-carious cervical lesions.

The prevalence of NCCLs is greater in incisors and premolars than abfractio canines and molars. This can prevent the occurrence of future abfractions.

Proceedings of the 1st European Workshop on Periodontology. A combination of different etiological factors will result in the initiation and further development of abfraction lesions that may differ in their clinical appearances.

As previously suggested, if abfraction is suspected to be a dominant factor in the etiology of NCCLs, then any decision to carry leskons destructive, irreversible treatment, such as occlusal adjustment, should be considered very carefully. This work is published and licensed by Dove Medical Press Limited. Some of the available treatment strategies may be tailored for abfraction lesions and others are used for NCCLs of all etiologies, depending on the patient factors and the severity of the problem.

When looking at abfraction lesions there are generally three shapes in which they appear, appearing as either wedge, saucer or mixed patterns. Discovering the cause or causes is an important first step to treatment and management. In cases of asymptomatic teeth, where tooth lesiosn and function are not compromised, abfraction lesions should be monitored for at least 6 months before any invasive procedure is planned.
