Abstract

Class II malocclusion — a common and complex pathology of the dentition, requiring early orthodontic treatment. The search for the new treatment appliances of it remains an urgent problem, because often children refuse to use complex orthodontic devices. The article presents the main results of the appliance application with own design for the class II malocclusion treatment in children aged 6 to 15 years. The study was conducted among 2 groups of patients: in the main group, an appliance with own design was used, in the control group — a twin-block was used. A comparative assessment of changes in biometric and cephalometric parameters at the end of treatment using different appliances in two groups was carried out. The degree of adaptation and the duration of orthodontic treatment were studied using a twin-block and an appliance of own design. It was revealed that the device of own design is effective in the treatment of class II malocclusion with a retroposition of the mandible, as well as a twin block. Its use helps to normalize the position of the teeth, the size of the dentition and the extension of the lower jaw to the front position relative to the upper jaw and base of the skull, which is mainly due to a decrease in the ANB angle and an increase in the angles of SNB, SNPog. Distinctive characteristics of the own design appliance are the creation of a tendency to rotate the occlusal plane counterclockwise, a more pronounced restriction of lower incisors protrusion and less restriction of upper incisors protrusion. In the group, where the own design appliance was used, children showed a higher degree of adaptation to it and, as a result, treatment was carried out in a shorter time.

Key words:

class II malocclusion, orthodontic treatment, the appliance for class II malocclusion correction, twin-block, children, adaptation
