Insignia固定矫治器定制系统在正畸治疗中的效果评价

Evaluation of the effect of Insignia system in customized orthodontic treatment

目的 :探讨Insignia固定矫治器定制系统在正畸治疗中的应用效果。方法 :选择2018年3月-2019年8月大连市口腔医院收治的错[牙合]畸形患者71例,应用随机数字表法分为定制组和非定制组。非定制组采用Damon Q自锁托槽治疗,定制组采用Insignia矫治系统定制个性化自锁托槽及弓丝治疗。初始校准阶段,每8周复查1次,此后每6周复查1次。比较2组的临床疗效、就诊次数、治疗计划时间、治疗持续时间、同行评估等级指数(PAR)及治疗过程中并发症和托槽情况。采用SPSS 20.0软件包对数据进行统计学分析。结果:定制组总有效率显著高于非定制组(P<0.05);2组治疗持续时间相比,差异无统计学意义(P>0.05);定制组就诊次数显著大于非定制组,治疗计划时间显著长于非定制组(P<0.05);2组患者治疗后的中线、牙错位、磨牙颊侧[牙合]关系、覆盖、覆[牙合]和加权总分均较治疗前有改变,定制组变化更明显(P<0.05);2组患者牙龈出血和托槽脱落率相比,差异无统计学意义(P>0.05);定制组托槽松动率显著高于非定制组(P<0.05)。结论:与非定制系统相比,Insignia矫治定制系统虽就诊次数多、治疗计划时间较长、托槽松动率高,但其效果较好。总体而言,对治疗持续时间影响不大,并未增加托槽脱落率。

PORPOSE:To investigate the effect of Insignia system in customized orthodontic treatment.METHODS:A total of 71 patients with malocclusion undergoing orthodontic treatment in Dalian Stomatological Hospital from March 2018 to August 2019 were enrolled,and divided into two groups according to random number table methods.Patients in non-customized group received Damon Q self-locking brackets,while patients in customized group received individualized brackets combined with Insignia appliance.The patients were revisited every 8 weeks in initial phase and thereafter every 6 weeks.The clinical efficacy,number of visits,time required for treatment planning and treatment duration were compared between the two groups.The severity of malocclusion,changes after treatment and improvement before and after treatment were evaluated by peer assessment rating(PAR).The complications and loose brackets during treatment were observed.SPSS 20.0 software package was used to analyze the data.RESULTS:The total effective rate of customized group was significantly higher than that of non-customized group(P<0.05).No significant difference was found in treatment duration between the two groups(P>0.05).The number of visits and time required for treatment planning of customized group were significantly longer than those of non-customized group(P<0.05).After treatment,the midline,tooth dislocation,molar buccal occlusion,overbite,overjet and weighted PAR total scores increased in both groups,and the increase was more significant in customized group(P<0.05).The gingival bleeding rate showed no significant difference between the two groups(P>0.05),while the rate of loose brackets was significantly higher in customized group than in non-customized group(P<0.05).CONCLUSIONS:Compared with non-customized system,insignia customized system has more visits,longer treatment planning time and higher bracket loosening rate,but its effect is better.In general,it has little effect on the treatment duration and does not increase the bracket shedding rate.
