Abstract

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.

摘要

目的

探讨Insignia系统在个性化正畸治疗中的效果。

方法

选取2018年3月至2019年8月在大连口腔医院接受正畸治疗的71例错牙合畸形患者，按随机数字表法分为两组。非个性化组患者采用Damon Q自锁托槽，个性化组患者采用个性化托槽联合Insignia矫治器。初始阶段每8周复诊1次，之后每6周复诊1次。比较两组的临床疗效、复诊次数、治疗计划所需时间和治疗时长。采用同行评估评分（PAR）评估错牙合畸形的严重程度、治疗后的变化以及治疗前后的改善情况。观察治疗期间的并发症和托槽松动情况。采用SPSS 20.0软件包进行数据分析。

结果

个性化组的总有效率显著高于非个性化组（P＜0.05）。两组治疗时长比较，差异无统计学意义（P＞0.05）。个性化组的复诊次数和治疗计划所需时间显著长于非个性化组（P＜0.05）。治疗后，两组的中线、牙齿错位、磨牙颊侧咬合、覆牙合、覆盖及加权PAR总分均升高，且个性化组升高更显著（P＜0.05）。两组牙龈出血率比较，差异无统计学意义（P＞0.05），而个性化组托槽松动率显著高于非个性化组（P＜0.05）。
