Abstract:
The present invention is a surgical template and method for drilling osteotomies (e.g., holes in a jaw bone), 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 template assemblyby a computer driven milling machine interfaced with a computer generated image of a patient's jaw bone, and a computer generated simulation of at least one dental implant so that when the template is placed in the patient's mouth a trajectory of the guides in the 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.
