Application of computer aided surgery technique in oral and maxillofacial surgery.

Computer aided surgery is a new technique for surgeons, which provides technical support through the virtual operation environment to make the operation more safe and accurate, and it is based on the high-speed management and control ability of the large amounts of data information by the computer. The computer assisted surgery can optimize operation scheme, provide real-time navigation, and improve the accuracy and quality of the operation. The operation has hecome more perfect with strict rich procedure and the operation risk can be reduced. This paper introduces the basic principle of computer aided surgery, the techniques related to computer assisted surgery mainly used in clinic, the advantages and disadvantages of these techniques and the application status in the oral and maxillofacial surgery.
