Abstract
A bone mill for preparing the second-stage opening in crestal bone surrounding the gingival surface of a dental implant in a jawbone is tubular in form and has teeth with a negative rake on an end surface and the adjacent side surface for forming a shaped opening to the implant. The side surface of the mill near the end surface is tapered to the desired shape of the opening. A guide pin fixed in the implant mates with an opening in the bone mill to center the mill relative to the implant.
