COMPARATIVE ANALYSIS OF ORTHODONTIC TREATMENT TERMS USING MINIIMPLANTS SKELETAL ANCHORAGE

Abstract

Introduction. The duration of orthodontic treatment is an important factor that serves as a criterion for assessing its quality and one of the determining factors for the success of treatment. The aim of the study. To compare the duration of orthodontic treatment in patients with the use of mini-implants and without the use of additional bone anchorage. Materials and methods. For orthodontic treatment, we selected 62 individuals who had defects in the posterior part of the dentition on the lower jaw (absence of the first permanent molar on one or both sides of the lower jaw), who were planned to undergo mesialization of the second and third permanent molars in order to replace the dentition defect with their own teeth. The first group included 32 individuals, and the second group included 30 individuals. The duration of orthodontic treatment was determined from the moment of installation of the bracket system to the moment of its removal and transition to the retention period of treatment. The results. The terms of complex treatment of dental patients with mesialization of molars differed in the two comparative study groups. In group I using orthodontic miniimplants as anchorage supports, the average duration of treatment was 2.19±0.05 years. In the second study group, in which mesialization of teeth was performed without the use of intraosseous anchorage, the average duration of treatment was 2.92±0.04 years. Thus, the treatment terms in the first study group using miniimplant-borne anchorage were reduced by 8.8±0.12 months compared to the second group (p<0.001). Conclusion. The obtained results indicate that the use of orthodontic miniimplants as anchorage supports during the lower molars mesialization contributes to the reduction of the overall terms of orthodontic treatment.
