摘要： A method and system for producing a dental implant surgical guide is disclosed. A patient-specific virtual model is generated using image data specific to a patient and virtual dental implants. The virtual model aligns the image data with the virtual dental implants using modeling software. A virtual mold is generated from the virtual model, and a physical mold is generated from the virtual mold. The physical mold is covered with a thermoplastic sheet via a thermoforming process. Excess thermoplastic material is trimmed off after the thermoforming process to produce a thermoformed piece. Metal tubes corresponding to each the virtual dental implants are placed onto the physical mold denoting the position, trajectory, and depth of the one or more virtual dental implants. A dental implant surgical guide that contains the thermoformed piece with the one or more tubes is produced.

摘要： A system and method for providing compact navigation-based surgical guide for dental implant surgery is disclosed. According to one embodiment, a surgical guide system comprise includes a surgical guide comprising having a tracking marker. The surgical guide is fabricated to be custom fitted to a patient's mouth or jawbone. The tracking marker is placed at an implant site according to a virtual implant plan. A sensor placed on a drill piece detects electromagnetic signals that are used to determine the position of the tracking marker. A computer in communication with the sensor processes the tracking marker data received from the sensor, determines a relative position of the drill piece with respect to the tracking marker, and provides real-time tracking of the drill piece on the display of the computer.

摘要： A system and method for providing magnetic based navigation in dental implant surgery is disclosed. According to one embodiment, a surgical navigation system comprises a custom piece that is made to fit in a patient's anatomy and comprises a first magnetic component. The surgical navigation system further comprises an instrument assembly comprising a drill bit and a second magnetic component. A processing unit receives and displays a first position and orientation data from the first magnetic component with respect to a second position and orientation data from the second magnetic component to track the movement of the first magnetic component with respect to the second magnetic component.
