Abstract
A surgical template and method for drilling osteotomies (e.g., holes in a jawbone) and installing one or more dental implants using a surgical template assembly. The surgical template assembly is provided with one or more drill guides and one or more dental implant guides. The guides are positioned in the surgical template assembly by a computer-driven milling machine interfaced with a computer-generated image of a patient's jawbone and a computer-generated simulation of at least one dental implant so that when the surgical template is placed in the patient's mouth a trajectory of the guides in the surgical template into the patient's jawbone corresponds to a trajectory of the computer-generated simulation of the dental implant into the computer-generated image of the patient's jawbone. Preferably, three fiducial markers, provide positional coordination between the CT scan data, the computer-generated simulation of the dental implant, and the computer-driven milling machine.
