Abstract

A prefabricated dental implant surgical guide. The implant surgical guide comprises a tooth shaped contour which simulates a natural tooth and the final prosthesis. The tooth shaped contours can be shaped to match any tooth found in the mouth. The system further comprises apical posts which protrude from the apical aspect of the tooth contour of the surgical guide. These apical posts are capable of marking an initial osteotomy site. The apical posts are further able to be placed in to an initial and developing osteotomy site to verify proper implant location, angulation and rotational position prior to implant placement. Significantly the apical post can be attached to the surgical guide and of a fixed length. The apical post can also be adjustable allowing continuous osteotomy site verification and removable allowing an implant surgical drill to pass thru it thereby allowing continuous osteotomy site development and verification. The system further comprises a coronal post aspect to position the surgical guide. The posts can be removed, the tooth contour aspect of the guide hollowed out and then relined and secured to the abutment aspect of an implant thereby functioning as a provisional crown or crowns. The prefabricated dental implant surgical guide can be used to place single implants or multiple side by side implants in a continuous fashion allowing verification of implant location, angulation and rotational position prior to implant placement leading to a more esthetic, functional and stable prosthesis.

Claims

1. A method for dental implant surgery comprising:

placing a prefabricated implant surgical guide in the mouth of a recipient at an implant site;

the prefabricated implant surgical guide consisting essentially of a single tooth-shaped contour having an apical end and a coronal end; and

a post affixed to the apical end of the tooth-shaped contour, the apical end post comprising a bottom face and a marking agent on the bottom face;

marking an implant osteotomy site via the marking agent on the bottom face of the apical post;

drilling a hole at the osteotomy site to an initial depth;

placing the prefabricated implant surgical guide apical end post into the hole at the osteotomy site, wherein the apical end post is dimensioned to fit within the hole of the osteotomy site; and

verifying the positional and angular alignment of the osteotomy site upon insertion of the apical end post into the hole of the osteotomy site.

2. The method for dental implant surgery of claim 1, wherein the apical end post comprises a length approximating a final depth of the osteotomy site.

3. The method for dental implant surgery of claim 1, wherein verifying the alignment of the osteotomy site comprises verifying the proper location, angulation, and rotational position of the tooth-shaped contour by comparing the tooth-shaped contour of the prefabricated dental implant surgical guide to other dental features of a patient with the apical end post of the surgical guide engaged in the osteotomy site.

4. The method for dental implant surgery of claim 1, wherein 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 an upper and lower jaw.

5. The method for dental implant surgery of claim 1, further comprising placing the tooth-shaped contour apical end at a proposed osteotomy site, causing the bottom face of the apical post to contact a jaw bone at the proposed osteotomy site thereby marking a drill site at the osteotomy site with the marking agent.

12. The method for dental implant surgery of claim 1 further comprising:

drilling the hole at the osteotomy site to a final depth;

placing the prefabricated implant surgical guide apical end post into the hole at the osteotomy site, wherein the apical end post is dimensioned to fit within the hole of the osteotomy site; and

verifying the positional and angular alignment of the osteotomy site upon insertion of the apical end post into the hole of the osteotomy site.

6. A method for dental implant surgery using a prefabricated dental implant surgical guide consisting essentially of a single 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 and an adjustable removable post located in the central bore, wherein the post comprises a post apical end that extends beyond the apical end of the tooth-shaped contour and a post coronal end that extends beyond the coronal end of the tooth-shaped contour, where in the method comprises:

placing the tooth-shaped contour in the mouth of a recipient at an implant site;

marking an implant osteotomy site via a marking agent on a bottom face of the apical end of the adjustable removable post;

drilling a hole at an osteotomy site to an initial depth;

placing the post apical end into the hole at the osteotomy site;

adjusting the length of the post apical end to the initial depth of the hole at the osteotomy site by manipulating the coronal end thereby extending the post apical end to the initial depth of the hole at the osteotomy site; and

verifying the alignment of the hole at the osteotomy site upon insertion of the apical end post into the hole at the osteotomy site by comparing the tooth-shaped contour position of the surgical guide to other dental features of a patient.

7. The method for dental implant surgery of claim 6, wherein placing the adjustable removable post apical end of the tooth-shaped contour into the hole at the osteotomy site comprises positioning the post apical end of the tooth-shaped contour into the hole at the site using the coronal end of the adjustable removable post to position the surgical guide.

8. The method for dental implant surgery of claim 6 further comprising deepening the osteotomy site hole to a final depth, and verifying the location, position and angulation of the osteotomy site by manipulating the coronal end of the adjustable removable post, thereby allowing the apical end to engage the depth of the osteotomy site;

and

comparing the tooth-shaped contour position to other dental features of a patient.

9. The method for dental implant surgery of claim 6 further comprising:

removing the adjustable removable post from the central bore of the tooth-shaped contour; and

placing an osteotomy drill through the central bore of the tooth-shaped contour while the tooth-shaped contour is engaged in the mouth of the recipient, thereby allowing the initial depth of the osteotomy site to be developed.

10. The method for dental implant surgery of claim 9 further comprising:

removing the adjustable removable post from the central bore of the tooth-shaped contour; and

placing an osteotomy drill through the central bore of the tooth-shaped contour while the tooth-shaped contour is engaged in the mouth of the recipient, thereby allowing a final depth of the osteotomy site to be developed.

11. The method for dental implant surgery of claim 6, 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 an upper and lower jaw.
