无托槽隐形矫治器与金属托槽直丝弓矫治器在口腔正畸中应用比较

Comparison of Application of Invisible Orthosis Without Bracket and Straight Bracket with Metal Bracket in Orthodontics

目的:探讨无托槽隐形矫正技术与固定矫正技术在口腔正畸中应用效果。方法:按随机数字表法将2016年6月~2019年1月本院接诊的需行牙齿正畸治疗患者94例分为两组,各47例。研究组行无托槽隐形矫正技术,对照组行固定矫正技术。比较两组临床指标、牙周指数。结果:研究组倾斜牙矫正时间、推磨牙向后时间、治疗时间与对照组相比较短,差异有统计学意义(P<0.05);研究组牙龈指数(GI)、牙齿松动度(TM)、龈乳头探诊出血指数(PBI)、牙周探诊深度(PD)与对照组相比较低,差异有统计学意义(P<0.05)。结论:无托槽隐形矫正技术应用于口腔正畸治疗与固定矫正技术相比,可缩短治疗时间,降低牙周指数,促进患者病情恢复。

Objective:To explore the application effect of invisible correction technique without bracket and fixed correction technique in orthodontics.Methods:According to the random number table method,94 patients requiring orthodontic treatment in our hospital from June 2016 to January 2019 were divided into two groups,47 cases each.The research group received invisible correction technique without brackets,and the control group received fixed correction technique.The clinical indexes and periodontal index of the two groups were compared.Results:Compared with the control group,the correction time of the inclined teeth,the time of pushing back the molars,and the treatment time of the research group were shorter than that of the control group(P<0.05);Compared with the control group,the bleeding index(PBI)and periodontal depth(PD)of gingival nipple probing were relatively low(P<0.05).Conclusion:The application of invisible correction without brackets in orthodontic treatment can shorten the treatment time,reduce the periodontal index,and promote the recovery of patients compared with fixed correction.
