The etched porcelain laminate veneer is a new conservative treatment that offers a solution to fractured, discolored, and worn anterior teeth. Preparation of enamel should be 0.5 mm to give minimal porcelain thickness and to avoid an overcontoured restoration. At the same time, dentinal exposure is contraindicated, because resin bonds better with enamel than with dentin. One hundred fourteen extracted teeth were measured at the gingival, middle, and incisal thirds. The resulting data reported on labial enamel thickness of anterior teeth may offer guidance in the preparation of laminate veneers.
蚀刻瓷贴面是一种新型的保守治疗方法，可为前牙折断、变色和磨损提供解决方案。牙釉质预备量应为0.5毫米，以使瓷层厚度最小并避免修复体外形过高。同时，禁忌暴露牙本质，因为树脂与牙釉质的粘结性优于与牙本质的粘结性。对114颗拔除的牙齿在牙龈、中部和切端三分之一处进行了测量。所得到的关于前牙唇面牙釉质厚度的数据可能为瓷贴面的预备提供指导。
