摘要：Background: Any deviation in the normal position of maxilla and mandible leads to skeletal malocclusion. Analyzing the Maxillary and Mandibular skeletal positions in a person is essential when planning orthognathic treatment. It involves surgically correcting the relationship of the maxilla and mandible to restore ideal occlusion. When the maxilla lies ahead of the mandible with reference to the anterior cranial base it is classified as Class II skeletal malocclusion or Maxillary Protrusion. This study aims at determining the incidence of maxillary protrusion in patients that undergo orthognathic surgery. Methodology: In this study we evaluated the records of different patients that Under went orthognathic surgery in Saveetha dental college and hospitals to determine the incidence of maxillary protrusion among the patients. The sample consisted of 59 patients. Statistical analysis was done using SPSS software. Descriptive statistics and Cross tabulations were done. Results: Majority of the patients that reported for orthognathic surgery were from the age group of 21-30 years. Among the other skeletal defects, prognathic maxilla with prognathic mandible showed the highest prevalence among the patients. Conclusion: Males were more prone to undergoing orthognathic surgeries. Mandibular arch is mostly affected in males and maxillary arch is mostly affected in females. We can conclude that prognathic maxilla is more prominently found in females.
