A self-limiting dental composite restoration sculpting bur particularly adapted for sculpting occlusal resins. Because of the cuspal angle of its cutting surface, the bur will make cuts that closely match the naturally occurring topography of human teeth as well as provide a visual stop that indicates when the desired cutting depth has been reached. The apparatus also includes a diamond coated cutting surface that is of such a roughness that it creates a physical stop that sends a tactile response to the operator when the bur contacts enamel. This tactile response ensures that the operator can avoid overcutting the restoration. In addition, a non-diamond coated annular band can be provided on the cutting head to create a safe zone which serves a further limit stop. The bur is mounted on a straight shaft to allow maximum vertical adjustment when mounted to a standard dental drill. The advantages include a visual depth stop, a physical stop, a shape that matches naturally occurring topography, and using a straight shaft to maximize vertical adjustability.
