ABSTRACT:
A dental drill is provided which includes a drill head carrying a drill bit and a telescopic drilling template to be attached to the drill head so that after a first hole has been drilled in the tooth with the drill bit, the template is inserted in that hole, thus insuring that a second hole parallel to the first hole is drilled with a desired spacing corresponding to that of the two pins of a dental prosthesis.
