A conservative method of replacing missing teeth is described. The fixed partial denture incorporates a resin-bonded retainer for the intact tooth and a telescopic coping for the carious or fractured tooth. A permanently cemented coping beneath a provisionally cemented superstructure provides the opportunity to recement the prosthesis if the acid-etched retainer is debonded. The advantages of this technique include conservation of enamel on the intact abutment and protection from leakage caused by dissolution of temporary cement on the abutment with a telescopic coping.
描述了一种修复缺失牙的保守方法。固定局部义齿包括用于完好牙齿的树脂粘结固位体和用于龋坏或折断牙齿的套筒冠内冠。如果酸蚀固位体脱粘，在临时粘结的上部结构下方永久粘结的内冠提供了重新粘结修复体的机会。该技术的优点包括保留完好基牙上的牙釉质，以及通过套筒冠内冠防止临时粘结剂在基牙上溶解导致的渗漏。
