Abstract
Nowadays, the surgical prediction for orthognathic surgery using Computer-Aided Surgical Simulation (CASS) planning program has become the main trend in three-dimensional (3D) applications for patients with skeletal discrepancies. So, this study was aimed to assess the accuracy of surgical prediction by CASS planning program to treat two-jaw orthognathic surgery in skeletal type III non-growing patients. Nineteen participants were treated by orthodontic-orthognathic surgery. The first CBCT scans and 3D virtual model scans were presurgical recorded 2-4 weeks (T0). The simulation plans were generated by software, Simplant O & O, and were transferred to the operating room by 3D splints. The second CBCT scans were postsurgical recorded 2-6 weeks after surgical procedures or splint-off period. (T1). The differences between T0 and T1 were compared by linear and angular measurements relative to 3 planes, Frankfort Horizontal Plane (FHP), Midsagittal Plane (MSP), and Coronal Plane (CP), respectively, and statistically analyzed by one-sample t-test and intraclass correlation coefficient (ICC). For repeated measurement, ICC showed an excellent correlation (0.787–0.998). Statistically significant differences were found in U6L to FHP, L6R to MSP, PP to FHP, MP to FHP, and MP to MSP with P-value less than 0.05. The overall mean linear and angular differences were 0.57 mm and 0.93 degrees. The overall linear and angular differences were within the acceptable criteria which could be interpreted as clinical insignificance. The mean intraclass correlation coefficient was 0.94 for the simulation plans and 0.95 for the actual outcomes. The application of CASS planning program for two-jaw orthognathic surgery in skeletal class III patients had acceptable accuracy which facilitated diagnosis and surgical planning effectively.
