Skeletal patterns underlying class III malocclusion
Introduction: The Skeletal Class III malocclusion is characterized by mandibular prognathism, maxillary deficiency or both.The aim of this study was to find out different skeletal pattern of class III malocclusion in patients seeking orthodontic treatment at Khyber College of Dentistry.
Material and Methods: The study was carried out on patients presenting with skeletal class III relationship from January 2009 to January 2011. The patients were selected from the orthodontics files of the Department of Orthodontics, Khyber College of Dentistry.
Results: Out of the total patients, 83 patients were found to have skeletal class III. Seventy one (85.5 %) cases were diagnosed as true skeletal class III malocclusions. The skeletal discrepancy was highest in mandible 50.74 %, followed by combination of mandibular and maxillary disharmony 28.16 %, maxillary involvement alone as 19.12 %.Conclusions: The different skeletal types would help in the evaluation of treatment effects in Class III malocclusion.
