The accumulation of experimental and clinical evidence during the past decade has significantly contributed to the understanding of the role of occlusally generated tensile stress in the etiology of certain noncarious cervical lesions of teeth. More important, this knowledge has led to the understanding of the reasons why traditional restorative treatments of these stress-induced cervical lesions fail. The case of failure can be attributed to the occlusally generated stresses that are concentrated at the cervical region and result in debonding, leakage, retention failure, and, ultimately, restorative failure. With the new understanding, restorative approaches that combine chemical adhesion and restorative materials of appropriate elastic properties show promise of long-term success.
在过去十年中积累的实验和临床证据，极大地促进了人们对咬合产生的拉应力在某些非龋性牙颈部病变病因中所起作用的理解。更重要的是，这一认识使人们明白了为什么对这些由应力引起的颈部病变进行传统修复治疗会失败。治疗失败的原因可归结为咬合产生的应力集中在颈部区域，导致粘结失败、渗漏、固位失败，最终导致修复失败。有了新的认识，结合化学粘结和具有适当弹性性能的修复材料的修复方法有望取得长期成功。
