摘要
目的本文旨在分析和研究牙列末端磨牙残根残冠进行桩核冠修复的临床效果。方法对单侧牙列末端磨牙残根残冠经过完善根管治疗后制作分杈式铸造桩核,龈距过低者面增加洞型固位,临床粘接后完成全冠修复。结果随访3～5年,78例病例桩核冠与牙体组织密合度良好,修复体无松动、脱落,功能良好。X片无继发龋,无根折。结论对经完善根管治疗的牙列末端磨牙残根残冠进行桩核冠修复远期效果肯定,值得临床推广应用。
Objective This paper aims to analyze and research the dentition of end of molar residual roots and crowns for restoration.Methods Unilateral edentulous distal molar residual root and crown after root canal therapy after making branch type casting post and core,and gingival from excessively low occlusal surface to increase the hole type retention,clinical bonding after completion of full crown restoration.Results Follow-up of 3-5,78 cases of postcore crown and the tooth tissue density and good,restoration without loosening,shed,good function.X no secondary caries,rootless fold.Conclusion The perfect root canal therapy at the end of the dentition of molar residual root and crown of post-core crown restoration of long-term effect,worthy of clinical application.
