Abstract
Dental crowding in mixed dentition is one of the most common orthodontic pathologies nowadays. According to modern literature database it’s prevalence reaches 77% and present at all occlusion periods, which is a significant sign of malocclusion’s severity. The aim of our research is to develop rational treatment protocol of patients with dental crowding during mixed dentition period according to facial skeleton growth patterns and also to make comparative analysis of treatment efficiency by using traditional and suggested protocol. Patients in mixed dentition period with dental crowding (n=164) were examined over a period of last three years at the base of NMU O.O. Bogomolets Dental Center, Kyiv. A total of 328 CBCT sections of facial skeleton (medium FOV) before and after treatment were submitted to the general analysis. The results and conclusions of treatment efficiency analysis were carried out by using the suggested protocol of dental crowding treatment with different facial skeleton growth patterns. Results indicated an improvement in treatment efficiency of this pathology and significant treatment time shortening. The results obtained after 16 months in patients with a horizontal growth pattern indicate that treatment efficiency value of clinical group (CG) II patients was 58.1±1.3%; after 17 months in patients with vertical and neutral growth patterns, treatment efficiency value of CG III was 66.7±1.6%, CG I - was 52.3±0.9%. The algorithm proposed by us allows to shorten treatment duration by 3-4 months.
