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.

Abstract: A dental drill is disclosed which allows for an osteotomy to be formed in a shape which closely matches the cylindrical shape of many dental implants. In so doing, the implant engages more tissue of the resulting osteotomy, thus resulting in greater ability for the tissue to penetrate and fuse with the implant while also reducing the chances of infection and reducing the overall recovery time. In addition, by forming the dental drill with a relatively obtuse angulation between the termini of the drill flutes, the cutting forces are spread across a larger cutting area thus reducing wear on the drill itself. Moreover, by spreading the cutting force over a larger area, the heat generated by the drill is reduced and thus the discomfort afforded to the patient is reduced.
