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.
