Abstract:
OBJECTIVETo study the difference of condylar morphology with different vertical facial types of skeletal III malocclusions in mixed dentition.
METHODSOrthopantomograms of 60 children with different vertical facial types were retrospectively investigated by computerized cephalometric analysis. Condylar morphology was compared among different vertical facial type groups.
RESULTSThere was statistical difference in upper condylar height among groups, the height increased from high angle group, average angle group to low angle group. There was no significant difference in ramus height in the groups. There was statistical difference in the upper condylar height to the ramus height radio in different vertical facial type groups (P < 0.01). The ratio increased from high angle group, average angle group to low angle group. There was no significant difference in the condylar height to the condylar neck width ratio in the groups.
CONCLUSIONIn children of skeletal III malocclusions in mixed dentition with different vertical facial types, there are statistical differences in condylar morphology, which might be due to different growth of mandibular.
