Abstract
Abstract A milling tool for preparing teeth for the placement of artificial peg teeth comprises a shaft provided with a milling cutter comprising a leading end portion of the shaft conically tapered toward a leading end of the milling tool and having a truncated conical surface on which three cutting blades are circumferentially disposed equally spaced. A portion of the truncated conical surface near the leading end of the milling tool functions as a pilot and guides displacement of the milling tool to position it during milling operations.
