This report describes crown lengthening and ridge recontouring to facilitate the provision of an aesthetic bridge pontic. A short clinical crown on one of the abutment teeth and a prominent edentulous ridge were probably related to a traumatic episode which caused the avulsion of the missing incisor in childhood.
本报告描述了牙冠延长术和牙槽嵴重塑术，以利于提供美观的桥体。其中一个基牙上的临床牙冠短小以及无牙牙槽嵴突出，可能与童年时期导致缺失门牙脱落的一次创伤事件有关。
