Dental implant surgical guide

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 aesthetic, functional and stable prosthesis.

1 . A prefabricated dental implant surgical guide consisting essentially of:
 a single tooth-shaped contour having an apical end and coronal end;   a post affixed to the coronal end of the tooth-shaped contour;   a post affixed to the apical end of the tooth-shaped contour; and   wherein the coronal post is used for positioning the tooth-shaped contour and the apical post of the implant surgical guide into the implant osteotomy site and wherein the apical end post is dimensioned to fit within a hole created by a surgical drill during an implant osteotomy site preparation procedure; and whereupon insertion of the apical end post into the implant osteotomy site, a proper positional, rotational and angular alignment of the implant to the osteotomy site is verified.   
   
   
       2 . The prefabricated dental implant surgical guide of  claim 1 , wherein the apical end post comprises a length approximating a finished depth of the osteotomy site. 
   
   
       3 . 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 . The prefabricated dental implant surgical guide of  claim 1 , wherein the apical end post and coronal end post posts are removable from the tooth-shaped contour of the surgical guide, thereby allowing the tooth-shaped contour to be attached to an abutment aspect of a dental implant, thereby serving as a provisional crown. 
   
   
       5 . The prefabricated dental implant surgical guide of  claim 1 , wherein the apical end post comprises a bottom face, the bottom face further comprising a marking agent for marking and locating an initial implant osteotomy site, prior to drilling the osteotomy site. 
   
   
       6 . A prefabricated dental implant surgical guide consisting essentially of:
 a single tooth-shaped contour having an apical end and a coronal end, wherein the tooth-shaped contour comprises a central bore along an axis extending from a center of the apical end through a center of the coronal end; and   an adjustable removable post located in the bore, wherein the adjustable removable post comprises a post apical end extending beyond the apical end of the tooth-shaped contour, and a post coronal end extending beyond the coronal end of the tooth-shaped contour and wherein the adjustable removable post is adjustable by moving the post along the axis of the central bore; and   wherein the post apical end is adjusted thereby extending the post apical end into a hole created by a surgical drill during an osteotomy site preparation procedure; and   whereupon insertion of the post apical end in to the osteotomy site, a proper positional, rotational and angular alignment of the implant to the osteotomy site is verified.   
   
   
       7 . The prefabricated dental implant surgical guide of  claim 6 , wherein the post coronal end is used for positioning the tooth-shaped contour and apical post end of the surgical guide into the osteotomy site. 
   
   
       8 . The prefabricated dental implant surgical guide of  claim 6 , wherein the adjustable removable post is removable and wherein an implant osteotomy drill can be placed within the central bore to initiate an osteotomy site preparation. 
   
   
       9 . The prefabricated dental implant surgical guide of  claim 6  further comprising a handle on the tooth-shaped contour used to stabilize the tooth-shaped contour during osteotomy site preparation through the central bore. 
   
   
       10 . The prefabricated dental implant surgical guide of  claim 8  wherein the adjustable removable post can be interchanged with the osteotomy drill to continuously verify implant osteotomy site location and angulation during the osteotomy preparation process. 
   
   
       11 . The prefabricated dental implant surgical guide of  claim 6 , wherein the adjustable removable post is removable from the tooth-shaped contour of the surgical guide, allowing the tooth-shaped contour to be attached to the abutment aspect of a dental implant and thereby serve as a provisional crown. 
   
   
       12 . The prefabricated dental implant surgical guide of  claim 6 , wherein the shape of the tooth-shaped body 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. 
   
   
       13 . The prefabricated dental implant surgical guide of  claim 6 , wherein the apical end post comprises a bottom face comprising a marking agent for marking and locating an initial osteotomy drill site prior to drilling the osteotomy site.
