A method is described by which porcelain laminate veneers are used to reinforce crown-fractured incisors which have been restored by reattachment of enamel-dentin fragments using enamel etching and a dentin bonding system. In an experimental model using sheep incisors, it was found that fracture strength equal to that of intact incisors could be achieved by employing this method. This is in contrast to fracture strengths of reattached enamel-dentin tooth fragments without porcelain laminates which were only 50% of intact incisors. It is suggested that porcelain laminate veneers may be used to supplement fragment bonding, thereby enhancing dental esthetics and function.
本文描述了一种方法，即使用瓷贴面来加固冠折切牙，这些切牙是通过使用酸蚀法和牙本质粘结系统重新粘结釉质-牙本质碎片来修复的。在使用绵羊切牙的实验模型中，发现采用这种方法可以获得与完整切牙相等的断裂强度。这与未使用瓷贴面的重新粘结的釉质-牙本质牙碎片的断裂强度形成对比，后者仅为完整切牙的50%。建议使用瓷贴面来补充碎片粘结，从而提高牙齿的美观度和功能。
