摘要：
FIELD: medicine.SUBSTANCE: invention refers to medicine, namely to orthodontic dentistry, and is intended for use in treating maxillofacial anomalies on mass out-patient admission in dental offices, polyclinics and clinics. Patient is examined with X-ray diagnostic measures: orthopantomogram (OPTG), teleradiography (TRG), computed tomogram (CT) and selection of treatment strategy depending on severity of orthodontic pathology. That is followed by determining the amount of the bracket system based on the size of the incision and the shape of the orthodontic arch. That is followed by preliminary fixation of the bracket system on the patient's dental arches with the following selected setting of the orthodontic arch. At that initially installed arc in bracket slot is four-sided. Mounted arc can be either square or rectangular cross-section depending on analysis of OPTG, TRG, CT. Obligatory condition of the tetrahedral arc installation at the beginning of the orthodontic treatment is related to observance of the specified value of the arc force applied to the displaced teeth. At that, initially-installed arc in bracket slot is four-sided with observance of specified value of arc force, which should be equal and not exceed 80 grams per tooth, wherein at light or medium degree of crowding of teeth, where space deficiency is from 2 to 6 mm, initial arc of rectangular cross-section 0.016x0.022" is used with force of 80 g/tooth, and in severe and very severe degrees of crowding, where space deficiency is from 7 and more than 10 mm, using initial arc of square section of 0.016x0.016" with force of 80 g/tooth, wherein the arc fixation in the bracket system slots for the first month is carried out by elastic ligatures with subsequent replacement of the ligature ligatures with the metal ligatures, and the first arc change is performed only after 7–9 months with subsequent increase of the arc cross-section from 0.018x0.018 to 0.021x0.028 and the force of its load on teeth from 10
