First Claim
1. A method for locating a dental implant in a patient'"'"'s jawbone, said method comprising the steps of:
- fitting a CT scan appliance to a patient'"'"'s mouth, said CT scan appliance having at least one radiopaque fiducial marker;
obtaining CT scan data of the patient'"'"'s jawbone and said CT scan appliance;
computer generating an image of the patient'"'"'s jawbone from said CT scan data and a simulation of a dental implant; and
providing a computer-driven milling machine having a table including tooling locators and holes for locating said CT scan appliance;
coordinating said CT scan appliance to said computer driven milling machine, said fiducial marker providing coordination between said CT scan data, said computer generated simulation of said dental implant and said computer driven milling machine;
supporting said CT scan appliance on said computer-driven milling table;
coordinating said CT scan appliance to said computer driven milling machine;
drilling, via said computer-driven milling machine, a hole in said CT scan appliance to form a surgical template, said computer-driven milling machine being interfaced with said computer-generated simulation of said dental implant so that when said surgical template is refitted in the patient'"'"'s mouth, a trajectory of said hole into the patient'"'"'s jawbone corresponds to a trajectory of said computer-generated simulation of said dental implant into said computer-generated image of the patient'"'"'s jawbone;
fitting said surgical template to the patient'"'"'s mouth; and
guiding a drill through said hole in said surgical template and into the patient'"'"'s jawbone to form a hole in the patient'"'"'s jawbone.

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.
