ABSTRACT
THE AIM: Of the work is to develop and substantiate the method of minimally invasive complex orthodontic treatment of patients with constriction and deformation of the upper jaw in the period of permanent bite with the combined use of a bracket system, orthodontic devices for the expansion of the upper jaw and fractional photothermolysis to improve the effectiveness of complex treatment. MATERIALS AND METHODS: The results of complex treatment of patients with the deficiency of the upper jaw in the period of permanent bite are presented. Complex treatment consisted of orthodontic treatment using a bracket system, laser corticotomy, orthodontic devices for the expansion of the upper jaw. Ultrasound examination before and after the procedure was performed to obtain reliable results of laser impact on bone tissue. RESULTS: After conducting a clinical and radiological examination (using cone-beam computed tomography) of all patients and analyzing the data obtained, we have developed algorithms for therapeutic measures. As a result of orthodontic treatment aimed at the expansion of the upper jaw patients who underwent fractional photothermolysis procedure achieved the expansion of the upper jaw at both the dentoalveolar and skeletal levels. CONCLUSION: It was found that a comprehensive approach with minimally invasive effects can improve the effectiveness of treatment of patients with constriction and deformation of the upper jaw during the period of permanent bite and achieve stable treatment results.
