Abstract Introductioin: Crowded teeth represent a high-prevalence malocclusion in growing children. Interceptive orthodontic treatmMyobrace successfully corrected maxillary and mandibular anterior crowding, established normal overjetletal patterns and eliminate myofunctional habits during early development. Objective: This case report utilizes myobrace appliances for crowded teeth in a child. Case Report: An 8-year-old patient came to Hasanuddin University Dental and Oral Hospital along with his parents with the main complaint of non-erupting anterior teeth. Intraoral examination revealed crowding of the maxillary and mandibular anterior teeth. Lateral cephalometric analysis showed class I skeletal. Interceptive orthodontic treatment was performed with myofunctional appliance with myobrace type. Initial staging was done with myobrace K1 for 4 months. The second stage was carried out with myobrace K2 for 4 months. The third stage is carried out with myobrace K3 for 4 months. The results of the treatment obtained anterior teeth in the normal arch and facial appearance improved. Discussion: Discussion: The Myobrace appliance effectively retrained aberrant orofacial muscles, normalized tongue posture, and provided arch development via its built-in structural features (e.g., Dynamicore and Frankel cage). This myofunctional re-educationMyobrace successfully corrected maxillary and mandibular anterior crowding, established normal overjeturing the active growth phase. Conclusion: The maxillary and mandibular anterior teeth were corrected using myobrace appliance and obtained normal overjet and overbite, corrected mandibular anterior crowding and class 1 canine and molar relations.
