Abstract

The relationship between bridge failure and the periodontal ligament area of their abutments was studied in 156 dental bridges constructed for 132 patients. Of the bridges constructed at the College of Dentistry, King Saud University, 26.9% did not meet the published criteria of Ante's Law while 50.0% of those made in general dental practice did not meet the same criteria. However, radiographic evaluation of abutment teeth in 56 failed bridges revealed that there were only two cases with evidence of overloading the abutments.

摘要

在为132名患者制作的156个牙桥中，研究了牙桥失败与其基牙牙周膜面积之间的关系。在沙特国王大学牙科学院制作的牙桥中，26.9%不符合已发表的安特法则标准，而在一般牙科诊所制作的牙桥中，50.0%不符合相同标准。然而，对56个失败牙桥的基牙进行的影像学评估显示，只有两例有基牙过载的证据。
