Abstract

A prefabricated dental implant surgical guide. The implant surgical guide comprises a tooth-shaped contour which simulates a natural tooth shape and the final prosthesis. An impression of an edentulous area and existing teeth of a patient is taken. A stone model of the impression is then made. A tooth-shaped contour(s) is selected from a tooth-shape and size selector kit comprising tooth-shaped contours, the tooth-shaped contours having central bores and corresponding to the edentulous area are secured to the stone model. A matrix of the stone model is formed with the tooth-shaped contours in place. The matrix is then removed from the stone model while retaining the selected tooth-shaped contour(s). Surgical drill holes are created in the matrix aligned with the central bores of the selected tooth-shaped contours to create the implant surgical guide. The matrix, now functioning as a surgical guide is then placed into the mouth of the patient. An osteotomy site is initiated by placing a surgical drill bur through the surgical drill holes of the matrix and through the central bores of the selected tooth-shaped contours, while the selected tooth-shaped contours are stabilized in their proper position by the matrix. The tooth-shaped contours can also be made of a radio opaque material, which when contained in the matrix and worn by the implant patient allow it to function as a dental scan appliance.

Claims

1. A prefabricated dental implant surgical guide comprising:

a matrix formed around a tooth-shaped contour, the matrix created from a model replica of a patient'"'"'s existing dentition including an edentulous area;

the matrix further adapted to hold the tooth-shaped contour corresponding to a required implant site;

the tooth-shaped contour having an apical end, a coronal end and a central bore, the central bore dimensioned to permit passage of a surgical drill bur during an preliminary implant osteotomy site preparation procedure for the required implant site.

2. The prefabricated dental implant surgical guide of claim 1 wherein the tooth-shaped contour comprises a radio-opaque material whereby the prefabricated dental implant surgical guide functions as radiographic appliance.

3. The prefabricated dental implant surgical guide of claim 1 wherein the matrix further comprises a hole in the matrix located over the central bore of the tooth-shaped contour corresponding to the required implant site, whereby the surgical drill bur is inserted through the hole in the matrix into the central bore of the tooth-shaped contour while the matrix is in place in the mouth of the patient, to create an osteotomy site while the tooth-shaped contour is retained in its proper stabilized position in the matrix.

13. The prefabricated dental implant surgical guide of claim 1 wherein the shape of the tooth-shaped contour is selected from the group consisting of a central incisor shape, a lateral incisor shape, a cuspid shape, a premolar shape, and a molar shape of both upper and lower jaws.

4. A method for dental implant surgery using a prefabricated dental implant surgical guide comprising a tooth-shaped contour having an apical end and associated bottom face and a coronal end, the tooth-shaped contour comprising a central bore along an axis extending from a center of an apical end through a center of a coronal end, wherein the method comprises:

creating a model replica of a patient'"'"'s existing dentition including an edentulous area;

placing the corresponding tooth-shaped contour of the surgical guide on the edentulous area of the model replica corresponding to the implant site of the patient'"'"'s mouth;

attaching the tooth-shaped contour of the surgical guide to the edentulous area of the model replica corresponding to the implant site of the patient'"'"'s mouth;

creating a matrix of the model replica of the patient'"'"'s existing dentition including the edentulous area, with the tooth-shaped contour in place;

retaining the tooth-shaped contour of the surgical guide in the matrix in its proper location, angulation and position corresponding to the implant site;

placing the matrix, with the tooth-shaped contour in place into the mouth of the patient to support further implant procedures.

5. The method of claim 4 wherein the tooth-shaped contour comprises a radio-opaque material.

6. The method of claim 4 wherein the tooth-shaped contour comprises a non-radio opaque material.

7. The method of claim 5 wherein supporting of further implant procedures comprises imaging the mouth of the patient with an imaging procedure taken from the group consisting of x-ray, CAT scan, panorex, and MRI recording.

8. The method of claim 4 wherein supporting of further implant procedures comprises:

creating a hole in the matrix over the central bore of the tooth-shaped contour;

inserting a surgical drill bur through the hole in the matrix and the central bore of the tooth-shaped contour; and

creating an osteotomy site in the mouth of the patient using the surgical drill bur while the tooth-shaped contour is stabilized in its proper position in the matrix.

14. The method for dental implant surgery using a prefabricated dental implant surgical guide of claim 4 wherein the shape of the tooth-shaped contour is selected from the group consisting of a central incisor shape, a lateral incisor shape, a cuspid shape, a premolar shape, and a molar shape of both upper and lower jaws.

9. A method for creating a dental implant surgical guide comprising:

creating an impression of an edentulous area and existing teeth of a patient;

creating a model of the impression;

selecting from an implant surgical guide tooth-shaped contour selector kit comprising tooth-shaped contours, the tooth-shaped contours corresponding to the edentulous area, each tooth-shaped contour having a central bore therethrough;

securing a selected tooth-shaped contour to the model;

forming a matrix of the model with the tooth-shaped contour in place on the model;

removing the matrix from the model while retaining the selected tooth-shaped contour therein;

creating a surgical drill hole in the matrix aligned with the central bore of the selected tooth-shaped contour to create the implant surgical guide.

10. The method for creating a dental implant surgical guide of claim 9 wherein the tooth-shaped contours of the selector kit comprise a radio-opaque material.

11. The method for creating a dental implant surgical guide of claim 9 wherein the tooth-shaped contours of the selector kit comprise a non-radio-opaque material.

15. The method for creating a dental implant surgical guide of claim 9 wherein the shape of the tooth-shaped contour is selected from the group consisting of a central incisor shape, a lateral incisor shape, a cuspid shape, a premolar shape, and a molar shape of both upper and lower jaws.

12. A method for performing dental implant surgery comprising:

creating an impression of an edentulous area and existing teeth of a patient;

the endentulous area corresponding to an implant site;

creating a model of the impression;

selecting from an implant surgical guide tooth-shaped selector kit comprising tooth-shaped contours, the tooth-shaped contours corresponding to the edentulous area, each tooth-shaped contour having a central bore therethrough;

securing the selected tooth-shaped contour to the model;

forming a matrix of the model with the tooth-shaped contour in place;

removing the matrix from the model while retaining the selected tooth-shaped contour therein;

creating a surgical drill hole in the matrix aligned with the central bore of the selected tooth-shaped contour to create the implant surgical guide;

placing the implant surgical guide into the mouth of the patient;

creating an osteotomy site for the implant by placing a surgical drill bur through the surgical drill hole of the matrix and through the central bore of the selected tooth-shaped contour; and

creating an osteotomy site using the surgical drill bur while the selected tooth-shaped contour is stabilized in its proper position by the matrix.
