Abstract
Aim: The aim of the study was to determine if Splintless patient specific osteosynthesis are superior to computer guided splints regarding accuracy in bimaxillary orthognathic surgery.Methodology: The study was performed on 20 patients indicated for bimaxillary orthognathic surgery. Patients randomized into two groups; group I: Positioning guides & patient-specific CAD-CAM osteosynthesis (PSI) have been used and group II: Computer guided interocclusal wafers splints have been used with traditional mini plates, Radiographic assessment included superimposition of preoperative planning and postoperative CT scans.Result: All patients expressed satisfaction with the aesthetic outcome.There were statistically significance differences between the two groups regarding maxillary, mandibular body, right and left proximal mandibular segments superimposition.Conclusion: The results concluded that PSI and splints have adequate levels of accuracy, Although generally, PSI are more accurate in transmitting the virtual plan
