摘要
目的:探讨对不同的折裂后牙采取不同的治疗方法进行保存治疗的临床意义。方法:对86例后牙折裂不同类型采用不同的治疗方法—表浅的隐裂牙制备哑铃型洞型作光固化充填;累及牙髓的隐裂牙经根管治疗后用全冠修复保护;波及牙髓的折裂牙切除斜折线以上牙龈,经根管治疗后,以桩核固位,用全冠修复保护;纵折牙经钢丝结扎固定,根管治疗后用全冠修复。结果:1年内总有效率(成功和有效)达91.9%,2年内总有效率达87.5%,3年内总有效率达79.2%。结论:折裂牙的牙龈切除、裂隙的严密结扎与固定、大量调整牙尖斜面、氢氧化钙碘仿糊剂充填根管、用金属全冠修复保护等措施对提高折裂牙的保存率具有重要作用。
Objective To explore the clinical significance of several treatments for different fractured osterior teeth. Methods 86 fractured posterior teeth were treated with different methods The cracked tooth without pulp involvement was filled with light-cured composite resin after having been given the dumbbell shaped cavity preparation. The cracked tooth involving pulp was restorated with the full crown technique after given the root canal treatment.For each inclined fractured tooth the root canal treatment the post care anchoring technique and the full crown restoration were applied after having been given gingivectomy for the pare involved. The vertically fractured tooth was restorated with the full crown technique after the cohesion fixing method and the root canal treatment have been used . Results The overall efficacy in one year was 91.9% while 87.5% in two years and 79.2% in three years. Conclusion It is suggested that resecting the involved gingiva of the inclined fractured teeth cohering and fixing the crack closely regulating the cuspal level in a large quantity filling the root canal with paste indoform-calcium hydroxide restorating the cacodontia by metallic full crown etc. play an important role in raising the conservative effect of the fractured teeth.
