Abstract

A dental prosthesis having a guide hole formed therein. The guide hole is configured to guide a drilling for a screw, and configured to receive the screw, holding the prosthesis in place when screwed into the bone of a patient.

Claims

1. A method of forming and installing a dental prosthesis comprising the steps of:

identifying a drilling path of the patient, the drilling path being projected from a dental prosthesis into a bone of the patient, the dental prosthesis comprising;

a prosthesis body, the prosthesis being a replacement for a missing tooth, the body having a tooth-shape and formed to replicate the tooth of a patient and to be implanted into a mouth of the patient, the body comprising a top chewing face, a bottom implanting face, and side faces;

wherein the body forms a guide hole from the top face to the bottom face, the guide hole forming a channel sized to guide a drill, and sized to closely receive a drill bit to prevent the drill bit from straying off a path guided by the guide hole during a drilling operation;

a screw, the screw attached to the prosthesis body and engaged with threads within the guide hole, and the screw extending beyond the bottom implanting face; and

a filling within the guide hole closing an opening of the guide hole at the top chewing face;

forming the dental prosthesis, the guide hole being formed to align with the drilling path when the prosthesis bottom implanting face is positioned on an implantation area;

positioning the dental prosthesis in the implantation area of the patient;

drilling a screw hole in the bone of the patient, the hole configured for the receipt of a bone screw, the drilling comprising guiding a drill bit through the guide hole and into the bone; and

implanting a screw into the screw hole through the guide hole, the screw remaining partially in the guide hole and partially in the screw hole.

2. The method of claim 1 further comprising the step of adhering a tab extending from the side face of the prosthesis to an adjacent tooth once the prosthesis has been positioned in the implantation area.

3. The method of claim 2 further comprising removing the tab adhered to the adjacent tooth and the prosthesis after the screw has set in the bone.

4. The method of claim 1 wherein the step of identifying the drilling path comprises taking a three-dimensional X-ray, and analyzing the X-ray to identify the drilling path in the bone of the patient.

5. The method of claim 1 further comprising the step of filling the guide hole with a composite once the screw is implanted.

6. The method of claim 1 wherein the step of drilling comprises guiding the drill bit through the guide hole, the guide hole being sized to closely receive the drill bit and sized to prevent the drill bit from straying off the path guided by the guide hole.

7. The method of claim 1 wherein the dental prosthesis further comprising a tab extending from one side face of the body, the tab configured to be adhered to an adjacent tooth.

8. The method of claim 1 wherein the dental prosthesis further comprising a plurality of tabs, each tab extending from one side face of the body, each of the plurality of tabs being configured to be adhered to an adjacent tooth.

9. The method of claim 8 wherein the tab is adhered to the adjacent tooth, and wherein the body is mounted to a bone of the patient by a screw, the screw positioned at least partially in the guide hole.

10. A method of fixedly implanting a dental prosthesis comprising the steps of:

setting a dental prosthesis in an implantation area of a patient, the dental prosthesis having a guide hole through its height, the dental prosthesis having a top chewing face and a bottom implanting face, with the guide hole extending between the top chewing face and bottom implanting face, the guide hole sized to allow the passage of a drill bit;

drilling a screw hole in a bone of the patient, the drilling comprising guiding the drill bit through the guide hole, the guide hole guiding the drill bit as it drills into the bone; and

implanting a screw into the screw hole through the guide hole, the screw anchoring the prosthesis to the bone and remaining partially in the guide hole and partially in the screw hole, the implanting step permanently holding the prosthesis fixedly in place;

filling the guide hole with a filling once the screw is implanted, the filling closing an opening of the guide hole on the top chewing face; and

wherein the step of drilling comprises guiding the drill bit through the guide hole, the guide hole being sized to closely receive the drill bit and sized to prevent the drill bit from straying off a path guided by the guide hole.

11. The method of implanting a dental prosthesis of claim 10 further comprising the steps of:

identifying a drilling path of the patient, the drilling path being projected from the prosthesis into a bone of the patient; and

forming the dental prosthesis, the guide hole being formed to align with the drilling path.

12. The method of implanting a dental prosthesis of claim 11 wherein the step of identifying the drilling path comprises taking a three-dimensional X-ray, and analyzing the X-ray to identify the drilling path in the bone of the patient.

13. The method of implanting a dental prosthesis of claim 11 wherein the step of forming the dental prosthesis comprises scanning a removed tooth of the patient using a computer;

and

generating the prosthesis automatically using a computer controlled system based on the scanned removed tooth.

14. The method of implanting a dental prosthesis of claim 10 further comprising the step of adhering a tab extending from the side face of the prosthesis to an adjacent tooth once the prosthesis has been positioned in the implantation area.

15. The method of implanting a dental prosthesis of claim 14 removing the tab adhered to the adjacent tooth and the prosthesis after the screw has set in the bone.
