Manufacturing a dental implant drill guide and a dental implant superstructure
DC CAFCFirst Claim
1. A method of manufacturing a dental implant drill guide, comprising the steps of:
- a) imaging a jawbone with a reference to a frame of reference to produce a three-dimensional computer graphics model;
b) selecting at least one implant drill hole position for at least one dental implant using said model, said position being specified in three dimensions, including a hole termination point and orientation, and being referenced to said frame of reference,c) entering at least one set of implant drill hole position coordinates into a computer controlled precision manufacturing device; and
d) using said precision manufacturing device to provide a drill template body having a fixed orientation drill guide socket for each one of said at least one drill hole position entered in step c) with a corresponding position and orientation.

Abstract
Dental implant drill holes and the shape of a dental implant superstructure are chosen by creating a computer model giving jawbone structural details, gum surface shape information and proposed teeth or dental prosthesis shape information. The computer model shows the bone structure, gum surface and teeth images properly referenced to one another so that implant drill hole positions can be selected taking into consideration proper positioning within the bone as well as proper positioning with respect to the dental prosthesis. Similarly, manufacture of the dental implant superstructure used for fixed dental prosthesis or overdentures can be designed based on knowledge of the actual implant positions referenced to an image of the gum surface and proposed dental prosthesis.
