국문 초록

A-21-year-old female came to the clinic due to chewing discomfort and lack of psychosocial confidence. The patient appeared to have a long face with mild chin protrusion in terms of soft tissue profile. Dento-skeletally, the patient has a severe Class III molar relationship, narrow maxillary arch with buccally-tipped molars, wide mandibular arch with lingually-tipped molars, severe reverse curve of Spee and anterior open bite. Centric relation (CR) mounted models revealed premature contact on both maxillary and mandibular left second molars. Pretreatment cone-bean computed tomography (CBCT) images revealed a notable size discrepancy between left and right condyles. Given the suspected condylar instability, stabilization of the temporomandibular joints was prioritized prior to orthodontic treatment. Orthodontic treatment was initiated using a maxillary skeletal expander (MSE) and a mandibular Schwarz appliance, followed by full fixed appliances. Presurgical orthodontics were completed in 14.5 months without the use of any intermaxillary rubber bands and temporary anchorage devices (TADs). Bimaxillary surgery was done with Le Fort I osteotomy and bilateral sagittal splint ramus osteotomy (BSSRO). After confirming that excellent facial esthetics and mutually protected occlusion were achieved, the patient was debonded 3 months after surgery. The total duration of treatment was 19 months including presurgical orthodontics, surgery, recovery, and postsurgical orthodontics. Completed treatment results were maintained successfully during follow-up period of 3.1-years. Retention was managed using a maxillary centric relation (CR) splint for nighttime use due to bruxism and clenching, along with a mandibular circumferential retainer.
