METHOD AND KIT FOR DENTAL IMPLANT DRILLING GUIDES
First Claim
1. A method of drilling a dental implant socket for a dental implant screw in the mouth of a patient after extracting a tooth from the jaw bone of said patient, thereby forming an extraction socket in said jaw bone with at least one tooth root socket in said jaw bone corresponding to the position of at least one root of said tooth, said method comprising:
- while said extraction socket remains open and unhealed, placing a post device into said at least one tooth root socket;
wherein said post device is configured to determine the depth and angle of said tooth root socket relative to said jaw bone;
said post device additionally configured to also serve as a template for guiding a drill bit for drilling said dental implant socket at an optimal angle and depth for a dental implant screw;
wherein said optimal angle and depth for said dental implant screw need not be the same angle and depth of said tooth root socket;
using a position fixation device to preserve the position and orientation of said post device relative to said jaw bone;
removing said post device from said patient'"'"'s mouth; and
using said position fixation device to subsequently guide said drill bit to the optimal angle and depth for a dental implant screw.

Abstract
Method and kit for producing implant drilling guides positioned at the proper orientation to avoid inadvertent damage to critical regions of the patient'"'"'s jaw when drilling to place dental implant screws. The method works by placing a small post device with x-ray visible depth markers in the root socket of the patient'"'"'s tooth immediately after tooth extraction. The post device may additionally be configured to guide the drill at a position and angle that is different from that of the original tooth socket. This post device is used to construct a removable guide that anchors to the patient'"'"'s adjacent teeth, and preserves the location and orientation of the extracted tooth root. Once the root socket is filled in with new bone, the guide, in conjunction with the X-ray post depth information, can be used to direct drilling along the same route as the old tooth root, thus avoiding critical structures.

11. A kit for guiding a drill bit for drilling a dental implant socket for a dental implant in the mouth of a patient, using a tooth extraction socket with at least one tooth root socket in the jaw bone of said patient as a positioning reference, said kit comprising:
-
at least one post device configured to determine the depth and angle of said tooth root socket relative to said jaw bone; said post device additionally configured to also serve as a template for guiding a drill bit for drilling a dental implant socket at an optimal angle and depth for a dental implant screw; wherein said optimal angle and depth for said dental implant screw need not be the same angle and depth of said tooth root socket as determined by the depth and angle of said tooth root socket; and at least some materials for a position fixation device to preserve the position and orientation of said post device relative to said jaw bone. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19, 20)
