在牙周引导组织再生术中出现的问题及研究

Problems and Analysis Associated with Guided Tissue Regeneration

目的:分析牙周引导组织再生术在牙周缺损修复中出现的问题及讨论其原因。方法:回顾总结在48例牙周缺损修复术的其中4个失败病例的术前条件、术中所见和术后效果。结果:该4例术后两周复诊发现术区牙周塞治剂脱落、牙龈红肿、所植入的多孔骨无机材料颗粒或胶原膜自牙周袋溢出。结论:牙槽骨吸收形态和剩余牙龈量的多少与材料的固定有很大关系。而材料的固定则决定了牙周组织的再生效果。

Objective：To analyze the problems and the causes during the operation of repairing the defect periodonty by guided tissue regeneration. Method：Review and sum up the preoperative conditions, phenomenon during operations and postoperative imitates of 4 failed operations in 48 examples. Result：The 2 weeks later return visiting of these 4 cases showed that the periodontal pack had dropped, and the gum had become swollen, the porous bone mineral or resorbable bilayer membrane had over flomed. Conclusion：There is a strong relationship between the morphology of alveola resorption, the left quantity of geingiva and the degree of steading the material. At the same time, the degree of steading the material also determine the result of regeneration of periodontium.
