显微牙周外科技术在种植体周附着龈不足或缺失患者中的应用

Application of periodontal microsurgery in patients with insufficient or missing attached gingiva around implants

目的探究显微牙周外科技术在种植体周附着龈不足或缺失患者中的临床应用效果。方法回顾性分析2018年8月-2020年8月在本院治疗的80例种植体周附着龈不足或缺失的患者,按照随机数字表法分为观察组38例和对照组42例。对照组行传统口腔种植修复治疗,而观察组在传统口腔种植修复治疗基础上行显微牙周外科技术治疗,比较两组手术后总有效率、有效角化黏膜宽度、探诊深度、改良菌斑指数、出血指数。结果观察组总有效率97.37%高于对照组总有效率78.57%(P<0.05);观察组附着龈宽度高于对照组,观察组探诊深度、改良菌斑指数和出血指数均低于对照组(P<0.05)。结论显微牙周外科技术应用在种植体周附着龈不足或缺失患者中有较高的成功率,能够明显提高种植体周附着龈的质量。

Objective To explore the clinical application effect of micro periodontal surgery in patients with insufficient or missing attached gingiva around implants.Methods 80 patients with insufficient or missing peri implant attachment gingiva treated in our hospital from August 2018 to August 2020 were retrospectively analyzed,and they were randomly divided into observation group(38 cases)and control group(42 cases).The control group was treated with traditional prosthodontics,while the observation group was treated with micro periodontal surgery on the basis of traditional prosthodontics.The total effective rate,effective keratinized mucosa width,probing depth,modified plaque index and bleeding index were compared between the two groups.Results The total effective rate of the observation group was 97.37%,which was higher than 78.57%of the control group(P<0.05);The width of attached gingiva in the observation group was higher than that in the control group,and the probing depth,modified plaque index and bleeding index in the observation group were lower than those in the control group(P<0.05).Conclusion The application of periodontal microsurgery in patients with insufficient or missing peri implant attachment gingiva has a high success rate,which can significantly improve the quality of peri implant attachment gingiva.
