Manufacturing a dental implant drill guide and a dental implant superstructure
DC CAFCFirst Claim
1. A dental implant superstructure for supporting a dental prosthesis over a gum surface of a patient'"'"'s jaw in which a number of dental implants have been inserted comprising:
- a body of one-piece construction shaped on the basis of a computer model of the patient'"'"'s gum surface, the dentures of the dental prosthesis and the dental implants, said body being made of a homogeneous bio-compatible material and defining;
a plurality of dental implant abutting flanges adapted to be securely seated against corresponding dental implants inserted in a patient'"'"'s jawbone, and a gum tissue overlying bridge interconnecting said dental abutting flanges together in a fixed predetermined configuration in which said dental implant abutting flanges match said corresponding dental implants, said gum tissue overlying bridge offering a support structure having a shape established on the basis of said computer model so that the dental prosthesis be supported in a predetermined position on said gum tissue overlying bridge over the gum surface when said dental abutting flanges are securely seated on the dental implants.

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 position can be selected talking 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 position referenced to an image of the gum surface and proposed dental prosthesis.
