摘　　要：目的研究正畸拔牙与不拔牙治疗对临界病例治疗效果的影响,探讨错[牙合]差异指数和矫治结果之间的关系.方法采用回顾性研究,选用了既可拔牙治疗,又可不拔牙治疗的34例错[牙合]畸形患者为研究对象,评价患者术前的错[牙合]差异指数(DI值)和术后的治疗效果(OCTEEI值)及二者之间相关性.结果①治疗结束后,拔牙组OCTEEI值总分扣分多于不拔牙组,差异无统计学意义(P>0.05),但拔牙组侧貌项目OCTEEI值扣分少于不拔牙组,有统计学意义(P<0.05),其他各项目均无差异(P>0.05).②拔牙组和不拔牙组的DI总分与OCTEEI总分之间无显著相关性(P>0.05).结论①临界病例拔牙与不拔牙治疗均能够获得临床较为满意的疗效,但是拔牙治疗的患者可以获得更加理想的软组织侧貌;②临界病例术前错[牙合]差异指数与矫治结果之间无相关性.Objective To investigate the differences in therapeutic effects in orthodontic borderline cases treated with extraction or non-extraction,and to assess the correlation between DI(discrepancy index)and OCTEEI(Orthodontic Case Treatment Effectiveness Evaluation Index).Methods 34 orthodontic borderline cases were selected in the retrospective study.The DI and OCTEEI of the cases were acquired and statistically analyzed.Results①After treatment,the total OCTEEI score in extraction group was deducted more than that in no-extraction group and the difference was not statistically significant(P>0.05).However,in the aspect of profile,the deduction score in extraction group was less(P<0.05).②There was no significant correlation between the total DI score and the total OCTEEI score in both groups(P>0.05).Conclusions①Satisfying outcome can be attained in the orthodontic borderline cases treated either with extraction or non-extraction.However,patients who underwent extraction can get better profile.②There was no correction between DI and OCTEEI in borderline cases.
