摘要：Skeletal class III malocclusion represents dentofacial deformity with mandibular prognathism. Orthognathic surgery along with orthodontic treatment is required for the correction of mandibular prognathism. The surgical correction procedures in orthognathic surgery includes advancement of the maxilla, deprojecting the mandible or a combination of both. In the present study we assessed the incidence of mandibular prognathism who underwent surgical correction. Materials and methods: Data is extracted from Patient management software of Saveetha dental college. The data is segregated based on inclusion and exclusion criteria. The data includes patients who underwent surgical procedures for correction of jaws. The collected data is entered in MS Excel sheet, and transferred to SPSS for analysis. Chi square test is used for analysis. P value less than 0.05 is considered statistically significant. Results were made into graphs and evaluated. Results:16.44% patients underwent BSSO surgery for class 3 malocclusion in lower arch. 4.11% patients underwent genioplasty for chin correction. 1.37% patients underwent a combination of BSSO and genioplasty. Chi square test was done, p value was found to be statistically significant (p<0.05). Conclusion:Bilateral sagittal split osteotomy (BSSO), is the most commonly performed surgery for correction of the mandible. Within the limits of the present study, it is concluded that 16.44% patients underwent BSSO surgery for class 3 malocclusion in lower arch.
