Coronoid process morphology in subjects with different vertical jaws dysplasias

Abstract

Objectives:This retrospective cephalometric study was carried to evaluate andcorrelate the coronoid process morphology in three groups of subjects exhibitingdifferent vertical jaws discrepanciesMaterials and Methods: Each group consisted of 25 subjects, five cephalometricmeasurements for coronoid procress and 9 linear and angular measurements wereused to evaluate coronoid process, craniofacial and mandibular rotationmorphology.Results:There were statistically significant differences in coronoid processmorphology between normodivergent subjects and both hypodivergent andhyperdivergent subjects(P<0.05),and coronoid process measurements weresignificantly correlated with mandibular rotation measurementsConclusion: coronoid process morphology was found to be related to mandibular morphology and to the function of the temporal muscle.
