CORRECTION OF DENTAL ARCHES DIMENSIONS IN CHILDREN WITH DENTITION DEFECTS IN THE PERIOD OF MIXED OCCLUSION USING NON-REMOVABLE ORTHODONTIC PROSTHESIS APPLIANCE.

Monitoring of dental morbidity in children of Ukraine in recent years has shown an increase in diseases of dento-maxillaire anomalies and dentition defects, which is the result of reducing the level of specific resistance caused by declined social conditions of life and environmental situation. Today, there is a need for timely prosthetics of dentition defects in the period of mixed occlusion with the help of prosthesis designs, which have a positive effect on the harmonious development of the dento-maxillaire system and the body as a whole. The aim - to increase the effectiveness of orthodontic treatment of children with dentition defects in the period of mixed occlusion to prevent the development of secondary dento-maxillaire deformities. 47 children aged 6 to 11 years with dentition defects were examined and received orthodontic treatment. The examination included clinical, anthropometric, dunctional and radiological examination methods. Orthodontic treatment of all the patients was performed using a non-removable prosthesis appliance of our own design (Patent for a utility model №145538 from 28.12.2020). The main cause of dentition defects is the premature removal of temporary and permanent teeth due to caries complications - 83.0%. As a result of orthodontic treatment and normalization of transversal sizes of the jaws using a non-removable prosthesis appliance for the upper jaw, we were able to achieve a significant improvement in the measured sizes of the jaws. In particular, the expansion of the upper dentition in the area of pm by 3.4±0.7 mm, and in the area of mm - by 3.7±0.9 mm. Which proves the effectiveness of treatment with a non-removable prosthesis appliance in the period of mixed occlusion. The use of the proposed non-removable prosthesis appliance allows to prevent morpho-functional changes of the dento-maxillaire system in children, to correct the already formed anomalies of the dental arches, and at the same time, to replace the dentition defect.
