目的探讨保持器辅助治疗慢性牙周炎的效果及方法,为牙周炎治疗方法的改进提供依据。方法制备隙卡沟,取印模灌注石膏模型,制作Hawley于1920年设计的保持器标准型。将30例患者随机分为两组,每组15例,每组随机选取80颗病牙,辅助治疗组采用保持器和常规治疗,对照组只采用常规牙周治疗,对治疗前后的牙齿松动度(MD)、牙周袋深度(PPD)和牙周附着水平(PAL)进行检测。结果两组患者在治疗后MD、PPD和PAL均较治疗前明显改善,差异均有统计学意义(P<0.05),辅助治疗组和对照组治疗后比较只有MD的差异有统计学意义(P<0.05),PPD和PAL差异均无统计学意义(P>0.05)。结论慢性牙周炎治疗期间戴活动保持器,可保证牙体没有颊、舌向及近远中方向的活动度,对巩固牙周治疗的疗效及缩短疗程效果明显。
Objective To investigate the effect and method of adjuvant therapy for chronic periodontitis in order to provide basis for the improvement of periodontitis treatment. Method Gap gap groove was prepared, and the model was filled with plaster cast to make the holder standard designed by Hawley in 1920. Thirty patients were randomly divided into two groups, 15 cases in each group, 80 cases were randomly selected in each group. The adjuvant treatment group was treated with conventional and regular treatment. The control group was treated with conventional periodontal treatment. The tooth mobility before and after treatment (MD), periodontal pocket depth (PPD) and periodontal attachment level (PAL). Results The MD, PPD and PAL in both groups were significantly improved after treatment compared with those before treatment (P <0.05). There was only significant difference in MD between the two groups after treatment <0.05). There was no significant difference between PPD and PAL (P> 0.05). Conclusion During the treatment of chronic periodontitis wearing activity holder can ensure that the tooth has no buccal, lingual and near-distal direction of activity, the effect of consolidation of periodontal treatment and shorten the course of treatment is obvious.
