[Efficacy of vacuum-gradient therapy in reducing orthodontic treatment time].

UNLABELLED: The purpose of the study was to evaluate the efficacy of vacuum-gradient therapy in reducing orthodontic treatment time.

MATERIALS AND

METHODS

The study comprised 57 patients aged from 25 to 35 years (mean age 28.8±4.6 years) with teeth crowding divided into two groups. In group 1 (n=29) orthodontic correction was combined with vacuum-gradient therapy by means of modified «AVLT-Desna» device, while patients in group 2 (n=28) underwent orthodontic correction alone. Microhaemo- and lymphocirculation was studied by laser Doppler flowmetry.

RESULTS

Lymph draining and microhaemocirculation are impaired by teeth crowding. Orthodontic correction influences on microhaemo- and lymphocirculation of periodontal tissue on tooth movement and improves mechanisms of haemodynamic regulation.

CONCLUSIONS

The method of vacuum-gradient therapy combined with complex malocclusion correction allows to accelerate orthodontic treatment and to improve microcirculation in the moved teeth area.
