Assessment of Relative Bite Force Following Bi-Jaw Orthognathic Surgeries Using T-Scan
摘要
Patients with skeletal malocclusions undergo orthognathic surgery to achieve a superior facial esthetic profile. However, stable occlusion following orthognathic surgery is also paramount. This study was thus designed to conduct a functional analysis of occlusion, in terms of relative distribution of bite force in patients who underwent bi-jaw orthognathic surgeries using a T-Scan device.
Materials and MethodsA prospective study was carried out on 40 patients between the age group of 18–32 years having skeletal malocclusions requiring bi-jaw orthognathic surgeries. The relative difference in bite force between the right and left side was measured using a T-Scan pre-operatively and at third month post-operatively. The data were analyzed statistically.
ResultsThe study included 40 patients (14 males and 26 females) with a mean age of 22.7 years. The mean difference in bite force pre-operatively was 27.95% and reduced post-operatively to 16.85%.
ConclusionThe significant decrease in the relative bite force between the left and right side post-operatively implies an improved balance of occlusal load between the two sides and hence a more balanced occlusion post-orthognathic surgery.
