This study findings demonstrated that for Class I and Class III malocclusions OJ is not a good predictor of skeletal relationships in the sagittal plane.
The findings of this study demonstrate that OJ is not a good predictor of malocclusion (Class I, Class II and Class III) for skeletal relationships in the sagittal plane.
Childhood and adolescent changes of skeletal relationships.
Other authors believe that, in addition to inducing dentoalveolar changes, appliance may also alter maxillary and mandibular skeletal relationship during growth (Luder, 1981; Antunes et al.
The system is based on five questions related to the facial proportions and skeletal relationships
, the length and mobility of the upper lip, the relationship between the gingival line and the horizon, the length of the maxillary central incisor, and whether the CEJ (cementoenamel junction) is palpable in the gingival sulcus.
Vertically, there has been no change in the skeletal relationships.
The cephalometric analysis supports the clinical finding of a moderate Class II sagittal skeletal relationship (ANB: 7A).
Mesiocclusion skeletal relationships are connected to an osseous alteration usually accompanied by Class III dental relationships and anterior crossbite.
13) The latter suggest that the optimal period to improve Class III skeletal relationships with functional appliances is during early deciduous and mixed dentition.
Partially or completely edentulous and dentate subjects with class II or class III skeletal relationships (those with vertical and transverse discrepancies) were excluded from the study.
Future research should be performed to investigate other mandibular parameters in Class II and Class III skeletal relationships and other types of malocclusion using other radiographic angulations' images such as lateral cephalometric views.
In future, the effects of various vertical skeletal relationships
on the incisors inclination need to be studied utilizing more robust statistical analyses.
