- Abstract
Background/objectives: To select predictors related to cervical vertebrae maturation (CVM), dentoalveolar adaptation, head posture, and respiration on outcome of face-mask treatment. Materials/methods: Forty-six patients (24 boys and 22 girls) with skeletal Class III pattern whose CVM stages ranged from I to IV at pretreatment were selected. The observation period was 2.87 ± 1.77 years from the end of treatment. Negative overjet and overbite was regarded as unstable. CVM, 10 skeletal variables, 6 dental adaptation variables, 4 alveolar housing variables, an airway variable, and 2 head posture variables were chosen for discriminant analysis of initial characteristics between stable and unstable groups. Results: Measurements exhibiting strong correlations were distance from lower incisor to Nasion, B point (NB), Frankfort horizontal plane to Mandibular incisor Angle (FMIA), incisor overbite, body to anterior cranial base. Limitations: We missed muscle-related variables, which cannot be identified in a cephalogram. Conclusions/implications: Presence of non-skeletal cephalometricfactors more closely associated with stability of face-mask treatment rather than skeletal cephalometric factors at the initial stage are confirmed.
