牙种植根周围炎治疗的探讨

Exploration of the dental peri-implantitis therapy

目的从临床角度探索种植根周围炎治疗的方法，以便有效治疗病变的种植根。方法诊断为种植根周围炎者37例进行以下治疗：（1）常规治疗.（2）龈切术，（3）翻瓣术，（4）引导骨组织再生术。测量治疗前后根周袋深度、牙龈指数、松动度等各参数，并进行统计学处理。结果种植根周围炎经治疗27例愈合，继续良好地行使功能，治愈率71.05％;11例失败，予以拔除。治疗前后参数变化有着显著性差异（P＜0.01）。结论正确区分病变与失败种植根两种概念，早期治疗病变种植根有望获得成功，同时提出了种植根周围炎的诊断和愈合标准以及一系列治疗过程。

Objective Our study is try to establish the treatment method for periimplantitis from clinical aspect,so as to treat failing implant effectively. Methods Peri-implantitis was treated using four methods: (1)essential treatment, (2 ) gingivectomy, (3 ) flap operation, (4 ) guided bone regeneration (GBR ).Clinical peri-implant assessments included probing depth (PD), gingival index (GI), mobility (MOB), data analysis was carried out using signed-rank test. Results 27 cases were successfully treated,and the rate was 71. 05%. 11 implants were extracted, the parameters before and after treatment have significant difference.Conclusion It is essential to maintain good oral hygiene, determine the standard of diagnosis of periimplantitis and successful treatment.
