超声洁治联合药物和翻瓣刮治联合引导骨再生术治疗牙种植周围感染的效果比较

Comparison on effects of ultrasound scaling combined with drug therapy and flap pedicled combined with guided bone regeneration in the treatment of peri-implant infection

目的比较分析超声洁治联合药物治疗和翻瓣刮治联合引导骨再生术(GBR)两种方法治疗牙种植体周围感染的临床疗效。方法选取开封市口腔医院2015年12月至2016年12月种植体周围炎患者22例25颗种植体,根据治疗方式分为治疗组(11例12颗种植体,采用超声洁治联合药物治疗)和手术组(11例13颗种植体,采用翻瓣刮治联合GBR治疗)。分析记录两组治疗前后的探诊深度(PD)、龈沟出血指数(SBI)、菌斑指数(PLI)和X线数据等指标变化。结果治疗组和手术组治疗后1、6个月PD、SBI、PLI均下降,且手术组治疗后1、6个月种植体周围牙槽嵴高度提高,治疗组治疗后6个月种植体周围牙槽嵴高度高于术前,差异有统计学意义(P<0.05)。结论两种治疗方法对种植体周围感染都具有很好的治疗效果,但翻瓣刮治联合GBR可促进种植体和骨更好地结合。

Objective To compare and analyze the clinical efficacy of ultrasound scaling combined with drug therapy and flap pedicled combined with guided bone regeneration (GBR) in the treatment of peri-implant infection. Methods Twenty-five implants of 22 patients with peri-implantitis treated in Dental Hospital of Kaifeng from December 2015 to December 2016 were selected. According to the treatment methods, patients were divided into treatment group (11 cases with 12 implants, treated by ultrasound scaling combined with drug therapy) and operation group (11 cases with 13 implants, treated by flap pedicled combined with GBR). The changes of pocket depth (PD), gingival sulcus bleeding index (SBI), plaque index (PLI) and X-ray data of the two groups before and after treatment were analyzed and recorded. Results The levels of PD, SBI and PLI decreased 1 month and 6 months after treatment in treatment group and operation group. The height of alveolar ridge around implants increased 1 month and 6 months after treatment in operation group, and the height of alveolar ridge around implants in treatment group 6 months after treatment was higher than that before operation, and the difference was statistically significant (P<0.05). Conclusions Both methods have good therapeutic effect on peri-implant infection, but the flap pedicled combined with GBR can promote integration of the implant and bone.
