We developed a new orthognathic surgical simulation system able to predict both occlusal correction and mandibular repositioning in three dimensions. This system uniquely integrates the real motion of the dental cast model with the virtual motion of the reconstructed cranio-facial model. The skeletal change of the mandibular osteotomy is simulated on the PC monitor while the occlusal change is confirmed by checking the cast model on the simulator. The simulation process is easily repeated and the operator can make several attempts to determine the final mandibular position. The occlusal relationship at the simulated mandibular posture is registered and the occlusal wafer splint, which ensures intermaxillary fixation, is fabricated on the simulator. This surgical simulation system appears to satisfy clinical demands well and is an important facilitator of communication between orthodontists and surgeons. Here, we outline the system and apply it to a demonstration case of orthognathic surgery.
我们开发了一种新的正颌外科手术模拟系统，该系统能够在三维空间中预测咬合矫正和下颌重新定位。该系统独特地将牙模模型的真实运动与重建的颅面模型的虚拟运动整合在一起。下颌骨截骨术的骨骼变化在电脑显示器上进行模拟，而咬合变化则通过在模拟器上检查牙模模型来确认。模拟过程易于重复，操作人员可以多次尝试以确定最终的下颌位置。记录模拟下颌姿势时的咬合关系，并在模拟器上制作确保颌间固定的咬合导板。这种手术模拟系统似乎很好地满足了临床需求，并且是正畸医生和外科医生之间沟通的重要促进工具。在此，我们概述该系统并将其应用于一个正颌外科手术的示范病例。
