Introduction: The aim of this study was to determine the Cephalometric characteristics of skeletal openbite using the quadrilateral analysis to Pakistani male and female patients with anterior open bite and to compare the male and female open bite subjects.
Methodology: The total sample comprised of 80 pretreatment lateral Cephalometric radiographs, seeking treatment in the dept. of orthodontics, Lahore Medical & Dental College, Lahore.
Results: Mean age of the study sample was 17.5 years. Maxillary and mandibular base lengths were significantly smaller in open bite patients. However, the anterior facial height, < Sag, < UF, MxE, MnE, (MaxL+MaxE)/MaxE were greater in open bite patients for both genders. ODI was larger in female open bite patients as compared to males.
Conclusion: Maxillary and mandibular base lengths are smaller in open bite patients than normal occlusion patients. Female openbite sample subjects had a convex profile while males had a straight profile.
