OBJECTIVE: This study evaluated the outcomes of treating anterior crossbite in early mixed dentition patients using the Myobrace appliance.
MATERIALS AND METHODS: A retrospective study was conducted on 30 Vietnamese children aged 6-10 years with anterior crossbite from 2020 to 2022. Oral habits, including tonguethrusting, lingual frenum interference, and tongue posture, were evaluated pre- and post-therapy. Clinical, radiographic, and soft tissue outcomes were assessed to monitor craniofacial, dental, and esthetic changes before and after treatment.
RESULTS: The mean age was 8.1 years (SD = 0.94), with 60% female participants. The average treatment time was 14.5 months (SD = 1.31). Tonguethrusting decreased from 23.3 to 3.3%, lingual frenum interference resolved completely (43.3 to 0%), and low tongue posture declined from 33.4 to 6.6%. Overjet improved from -2.5 (SD = 1.90) to 1.6 mm (SD = 1.14), and overbite reduced from 2.2 (SD =0.92) to 0.8 mm (SD =1.14). Maxillary and mandibular incisor angulations showed significant improvements: U1 to SN increased from 100.4° (SD = 7.14) to 109.5° (SD = 7.18), and IMPA decreased from 89.8° (SD = 8.77) to 87.0° (SD = 7.97). Most patients adhered to the recommended wear and exercise regimens, though 40% experienced appliance detachment in the first 2 weeks.
CONCLUSION: The Myobrace system effectively corrected anterior crossbite, improved oral habits, and enhanced dental alignment in early mixed dentition, promoting functional and esthetic improvements.
