【摘要】 目的:研究牙周辅助加速成骨正畸治疗(PAOO)在正畸治疗中的应用。方法:选取2017年6月-2020年1月于笔者所在医院进行牙齿正畸治疗的患者100例,按照随机数字表法将其分为研究组和对照组,各50例。对照组采取常规牙牵引正畸治疗,研究组采取PAOO治疗。比较两组牙间隙关闭时间、牙齿排齐时间、牙周健康状态、龈沟液炎性因子水平及不良情况发生率。结果:研究组牙间隙关闭时间、牙齿排齐时间均明显早于对照组,差异有统计学意义(P<0.05)。治疗后,两组角化龈宽度、探诊出血指数、菌斑指数、临床附着水平均较治疗前明显改善,且研究组改善程度优于对照组,差异有统计学意义(P<0.05)。治疗后,研究组龈沟液炎性因子水平均明显低于对照组,差异有统计学意义(P<0.05)。治疗后,两组牙根吸收发生率比较差异无统计学意义(P>0.05);研究组龋损发生率明显低于对照组,肿胀、疼痛及瘢痕发生率高于对照组,差异有统计学意义(P<0.05)。结论:与常规牙牵引正畸治疗方法相比,PAOO能够明显缩短正畸周期,改善牙周健康,但术后通常伴有肿胀、疼痛,易出现瘢痕,亟待改善。更多还原

【Abstract】 Objective:To study the application of periodontally accelerated osteogenic orthodontics (PAOO) in orthodontics treatment.Method:A total of 100 patients who underwent orthodontics treatment in our hospital from June 2017 to January 2020 were selected,and divided into the study group and the control group according to random number table method,with 50 patients in each group.The control group was treated with conventional traction orthodontics,the study group was treated with PAOO.The closing time of tooth space,alignment time of tooth,periodontal health status,the levels of inflammatory factors in gingival crevicular fluid and the incidence of adverse events were compared between the two groups.Result:The closing time of tooth space and alignment time of tooth in the study group were significantly earlier than those in the control group,the differences were statistically significant (P<0.05).After treatment,the width of keratinized gingiva,probing bleeding index,plaque index and clinical attachment level in the two groups were significantly improved compared with those before treatment,and the improvement degree in the study group was better than that in the control group,the differences were statistically significant (P<0.05).After treatment,the levels of inflammatory factors in gingival crevicular fluid in the study group were significantly lower than those in the control group,the differences were statistically significant (P<0.05).After treatment,there was no significant difference in the incidence of root resorption between the two groups (P>0.05).The incidence of caries in the study group was significantly lower than that in the control group,and the incidence of swelling,pain and scar were significantly higher than those in the control group,the differences were statistically significant (P<0.05).Conclusion:Compared with conventional traction orthodontics treatment,PAOO can significantly shorten the orthodontics cycle,and improve periodontal health,but it is often accompanied with swelling,pain and scar after operation,which needs to be improved.更多还原
