摘要牙齿磨损是复杂的、多因素交互作用导致的牙齿硬组织快速缺损。目前，牙齿磨损患者呈年轻化趋势且数量日益增加，对口腔修复医师的修复技能而言，是一个严峻的挑战。本文从牙齿磨损的病因学入手，根据牙齿磨损的类型和程度进行综合评估、诊断，并提出相应治疗方案：对轻中度牙齿磨损采用氟化物预防、树脂封闭、粘接性树脂修复；对重度牙列磨损经诊断蜡型设计，树脂罩面验证口内咬合关系，过渡性树脂修复使患者适应重建的咬合，之后采用树脂粘接技术结合微创美学修复，重建牙齿形态，有效恢复咀嚼功能，改善患者美观和发音。

abstractsTooth wear has complex and multi-factorial etiologies that result in the surface loss of dental hard tissues. Clinic prevention and restorative technology of tooth wear are challenge for dentists with the increasing numbers of population and the transition of disease age. From the etiology and classification of tooth wear, it is crucial to accurately assess and diagnose a patient presenting with tooth wear. Fluoride application, sealant and resin bonded restoration are beneficial to manage the mild tooth wear. For severe tooth wear, it is need to fabricate the diagnostic wax-up, and resin mock-up is also used to verify the occlusal relationship and vertical dimension increase, and then an interim restoration is also used to adapt the patient to the change of occlusion. Finally, by means of contemporary adhesive technique and min-invasive treatment, the dentist can reconstruct the shape of worn tooth, effectively restore the function of chewing and improve the appearance and pronounciation.
