The aim of the study was to improve the efficiency of orthodontic treatment, by use of MPI Mandibular Position Indicator. 34 patients aged 14 to 18 years were examined, of which 12 patients were included in the treatment group and divided into two groups of 6 people each. All patients underwent orthodontic treatment using the bracket system of active self-ligation of the direct arc technique, using the anthropometric system of quantitative estimation (The ABO Model Grading System) at the stage of alignment. Еarly orthodontic treatment and at the end of his patients first and second groups we analyzed the closing of dentition in centric occlusion and centric relation. As a diagnostic tool using the mandible position indicator MPI (Mandibular Position Indicator). In group 2, where the ABO system was used during the alignment phase with the repeated reframing of the required braces using the indirect bonding method, the ΔZ indicator for the right and left sides fixed by the MPI method was lower than in group 1 at a very high level of statistical significance p = 0.000003 and p = 0.00077, respectively). The mean values of the ΔX indicator for the left side in group 2 had a statistically confirmed downward trend compared to group 1 (p = 0.051342).
