Abstract

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.
