Class- III - malocclusion: a cephalometric study in a Pakistani population sample

ABSTRACT

This study was carried out to evaluate the Cephalometric characteristics of class-III malocclusion in a sample of Pakistani population with age range 18-25 years visiting Orthodontics department, de' Montmorency college of Dentistry / Punjab dental hospital, Lahore. Lateral Cephalometric radiographs, Orthopentomograms, Study casts, extra oral and intra oral photographs were taken for every patient. Results indicate that regarding the Cephalometric characteristics of Pakistani patients with class III malocclusion, the Maxilla showed retrognathism in relation to cranial base both for angular and linear parameters in antero-posterior relationship while the Mandible showed prognathism in relation to cranial base both for angular and linear parameters in antero-posterior relationship. However the Dento-alveolar measurements showed maxillary incisors proclination and mandibular incisors retroclination, suggestive of dental compensation to skeletal discrepancy. Males showed comparatively horizontal while females exhibited vertical growth tendency
