EFFECTIVENESS OF CROSSBITE TREATMENT WITH MYOBRACE I3 ON MIXED DENTIOTION
Main Article Content
Abstract
Children in mixed dentition age may have problems with breathing, chewing, swallowing, speaking, facial morphology and bad habits such as thumb sucking, mouth breathing... If detected early, Preventive treatment and timely treatment will minimize the problems of occlusal as well as maxillofacial function, making the future orthodontic treatment easier and more convenient. The use of functional applience such as Myobrace at the right time and right indication will contribute to changing the function of facial muscles, the shape of the teeth, helping the child's jaw to develop in the most favorable direction possible. The presentation will describe the design, function, indications and advantages of the functional orthodontic Myobrace I3 for children of mixed dentition. Objectives: To evaluate the change before and after treatment in clinical and cephalometric after treatment of crossbite on the early mixed dentition with Myobrace I3. Meterior and methods: The study was carried out on 30 patients with anterior crossbite in the mixed dentition age who came for examination and treatment at the Hanoi National Hospital of Odonto-Stomatology, using the results of the examination and treatment. clinical and radiographic. Using the Pair T Test, the difference was statistically significant with p<0.005. Results: The bad habit of pushing the tongue was eliminated 85.7%, tongue tie was completely eliminated 100%, the low tongue position was eliminated 80%. The mean duration of treatment until the reversal was 14.47 ± 1.31 months. The patient complied well with the treatment protocol. On Cephalometric: change of overbite after treatment increased 3.65mm; The angle of the upper incisors axis compared to the SNA base plane increased by 9.16o, this difference has statistical significance p<0.005. The skeletal change was not statistically significant. Conclusion: The Myobrace I3 functional applience resulted in functional; a major change in the teeth while the skeletal changes were negligible.
