Abstract
This study compares the fracture resistance of endodontically treated premolars with modified types of cavity preparations and restoration with either amalgam or composite resin. The greatest influence on fracture resistance was the remaining tooth structure. The effect of adequate wall support on tooth strength was compared with intact unprepared teeth.
摘要
本研究比较了经根管治疗的前磨牙采用改良型洞形预备并用银汞合金或复合树脂修复后的抗折性能。对抗折性能影响最大的是剩余牙体结构。将有足够壁支持的牙齿强度效果与未预备的完整牙齿进行了比较。
