Occlusal Analysis Using T-Scan in Patients With Condylar Fractures When Managed by Closed Method.

Abstract

The aim of the study is to assess the occlusion in mandibular condyle fractures using T-Scan and analyze the data obtained. Twenty patients underwent non-surgical management for condylar fractures were treated with Erich arch bar and guiding elastics, and periodically subjected to T-Scan III evaluations. The data obtained was analyzed with the clinical evaluation conducted. There were 18 males and 2 females. Mean age of the patients was 25.4 ± 7.4 years. There were statistically no significant changes in Centre of Force values, in Bite Force at First Contact (P < 0.05) during the study period. There were significant differences in Maximum Bite Force between preoperative and postoperative values, preoperative and sixth-month values, postoperative and first-month values, first-month and sixth-month values. There were significant (P < 0.05) differences in Bite Force at Maximum Intercuspation between preoperative and third month, preoperative and sixth-month values, postoperative and sixth-month values, first-month and consequent follow-ups. Subjective evaluation of occlusion revealed significant differences (P < 0.05) between preoperative and 1-month, preoperative and postoperative, postoperative and 1-month values. All patients improved by the end of 6 months with regards to their mouth opening. The center of force does not alter significantly in post trauma period. Mouth opening improves significantly at the end of 6-month period post-operative. Improvement in maximum bite force and maximum intercuspation take place simultaneously. Mouth opening improved significantly. Subjective evaluation of occlusion does not change significantly after the third month evaluation. Longer follow-ups would help us in understanding when or if the bite forces equilibrate after a condylar trauma.
