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.

Possible role of tensile stress in the etiology of cervical erosive lesions of teeth. Marcy Goldin and Dr. Bioengineering studies have discovered the association between wear at the cervical region and occlusal stresses by employing finite elemental analysis or photo-elastic methods [ 232526 ].

Always seek the advice of your dentist or other qualified healthcare provider with any questions you may have regarding a medical condition or treatment. It is not intended to be a substitute for professional advice, diagnosis or treatment.

A Review of the Literature. Noticeably, clinicians have long been misled by articles that proposed treatment recommendations for abfraction without credible scientific data. Guidelines for the enhancement of esthetics may help the patient when selecting treatment options after they have recognized their goals. As professionals, dentists should not impose their esthetic concerns on the patient.

In conclusion, it is observed that there is weak relation between the occlusal factors and the NCCLs [ 3 ]. As previously suggested, if abfraction is suspected to be a dominant factor in the etiology of NCCLs, then any decision to carry out destructive, irreversible treatment, such as occlusal adjustment, should be considered very carefully.


Diagnosis of erosion may not be easily accomplished because patients may not volunteer information as in cases of eating disorders, or patients may not link heartburn or stomach upsets with teeth defects.

The assessment of lesion activity can be performed every 6 months to 12 months and during regular hygiene visits. Occlusal adjustment and occlusal splints As a result of the reported associations between occlusal stress and abfraction abfarction, occlusal adjustment has been proposed as an alternative treatment to prevent the initiation and progression of these lesions and to minimize failure of cervical restorations.

Causes of Abfraction Lesions The lesions have been attributed to mechanical stress from chewing function abfractipn teeth grinding. Some esthetic factors in a smile.

abfratcion About 37 percent of patients who continue to smoke after cancer treatment will develop second cancers of the mouth, throat or larynx. In vivo correlation of noncarious cervical lesions and occlusal wear. On observation, the severity of occlusal and cervical wear increases with age and therefore considered as natural physiological processes.

The prevalence of NCCLs is greater in incisors and premolars than in canines and molars. Figure 3 illustrates a clinical case of restorative treatment of NCCLs, in which the etiological factors were not addressed, leading to the continued progression of lesions and failure of restorations. In cases of abfraction associated with gingival recession, a combined restorative-surgical approach may be performed.

Guidelines Upcoming Special Issues. Furthermore, several indices of tooth wear lesione been proposed for recording and monitoring the progression of abfraction lesions or any NCCLs. Abfractioon predisposition to failure of restorations placed in NCCL area is observed because of the etiology of the lesions.

If you have a dental abfraction, you have probably developed a notch in your tooth near the gum line. A combination of different etiological factors will result in the initiation and further development of abfraction lesions that may differ in their clinical appearances.

On the longevity of teeth. In cases where the abutment tooth of a planned removable partial denture has abfraction lesions, then abfractikn resin bonded composite restorations should be the esthetic treatment of choice for dealing these type of cases, though the demerits would be accounted during removal and insertion of the prosthesis, which may result in wear lesion the restoration during prolonged use.

Restorative challenges for these lesions are also attributed to difficulty with moisture control, in gaining access to subgingival margins, 538 and in treating the sclerotic dentin, the most affected tissue due to these defects, with adhesive techniques. However, if the lesioons wear negatively involves with the long-term prognosis of the tooth, operative treatment may be required.
