Aim: The aim of the study was to assess occlusion in patients undergoing bi-jaw orthognathic surgeries (OGS). Materials and methods: A prospective study was done on 20 patients between the age-group of 18 and 32 years having skeletal malocclusions requiring bi-jaw OGS. The occlusal contacts of patients undergoing bi-jaw OGS were assessed in two phases using a T-scan device—(1) immediately prior to surgery and (2) after 3 months of orthognathic surgery. Patients were made to sit in a natural position with Frankfort horizontal plane parallel to the ground, occlusal contacts were recorded using specialized wafers, and information was recorded digitally using a T-scan device. Results: The study included 20 patients (7 males and 13 females) with a mean age of 22.7 years. The mean number of teeth in contact increased from 2.7 to 3.3 on the left side and 3.3 to 3.7 on the right side when assessed 3 months postoperatively indicating a significant improvement in postoperative occlusal contacts. Conclusion: The significant increase in the occlusal contacts over the left and right side postoperatively implies a better stomatognathic system and improved masticatory efficiency postorthognathic surgery. Clinical significance: Orthognathic surgery has been routinely performed to enhance the patient's facial esthetics, thus the concept of functional occlusion is sometimes forgotten. This study helps in assessing the functional aspect of orthognathic surgery in terms of occlusal contacts which is a keystone in a successful orthognathic surgery.
