OBJECTIVE: To compare the outcomes of occlusal plane cant correction versus conventional orthodontic treatment on temporomandibular joint (TMJ) status and craniofacial symmetry in children and adolescents with mild skeletal facial asymmetry.
METHODS: A total of 124 patients were enrolled and allocated into an occlusal plane cant correction group (n=61) and a conventional treatment group (n=63) according to the treatment protocol. Changes in occlusal plane cant, TMJ-related clinical symptoms, imaging parameters, and craniofacial asymmetry indices were evaluated before and after treatment.
RESULTS: The correction group achieved a significantly greater reduction in occlusal plane cant. After treatment, the incidences of TMJ clicking, tenderness, and deviation during mouth opening were significantly lower in the correction group. Imaging analyses showed superior condylar adaptive remodeling and improved joint space parameters in the correction group. In addition, craniofacial asymmetry improved more markedly in this group. The extent of occlusal plane correction was significantly associated with improvements in asymmetry indices and TMJ imaging parameters, and served as an independent predictor of TMJ symptom improvement.
CONCLUSION: In children and adolescents with skeletal facial asymmetry, accompanied by occlusal plane cant, active correction of the occlusal plane cant is more effective than conventional orthodontic treatment in improving craniofacial symmetry and enhancing TMJ health.
