Abstract: Summary：Surface defect of teeth is a common ailment in the oral cavity and its pathogenic factors are attrition， abrasion， erosion or crack of teeth. It can not only damage patient’s facial appearance， but also decrease patient’s masticatory efficiency， even result in endodontic disease and TMJ disease， and will eventually harm the life of the patient. The restoration of the surface defect of teeth should be based on the degree and extent of the defect after the pathogenic factors were removed. Localized and superficial defect could be restored with conservative method. While for extensive defect affecting the whole dentition， occlusion reconstruction should be adopted to restore the defect. As occlusion reconstruction is a complicated and irreversible restoration method， its indication should be carefully selected and the regular manipulation should be followed.

Key words: surface defect of teeth, attrition, erosion, restoration, occlusion reconstruction
