| Abstract Orthognathic surgery became a rapidly evolving procedure, innovations in virtual planning offers a potentially superior alternative to the conventional model surgery. The variation in techniques, virtual planning software’s, imaging machines and 3D printing options made virtual planning an appealing field, however, the accuracy of these methods remains subject to accuracy assessment. A virtual planning technique was elaborated and validated. Both intermediate a final wafer of seven orthognathic patients were tested revealing mean deviation in intermediate wafer group of 0.64±0.33 mm; while the mean deviation in final wafer group of 0.53±0.10 mm .The virtual technique adopted by our team for construction of occlusal wafers showed good fitting and almost no rocking or interference, minor interferences were caused by the remnants of the supports made during printed to support the 3D model during the process, these interferences were easily eliminated in the occlusal trial session with a finishing stone. In further model that complication was reduced by orienting the models during printing and relocating printing supports away from the fitting surface of the wafers. | ||||
