Abstract
A tooth crown marking device is comprised of markers at each end. The marker at one end is for marking a specified vertical landmark on the face of a tooth crown. The marker at the other end is for marking the horizontal center of a tooth crown. At that end, there is a pair of locating members adjustably mounted on either side of the horizontal marking arm in such a manner that the marking arm is maintained equidistant from the locating members. Pointers at the end of each locating member are adjusted to span the height of the crown. The horizontal center of a tooth crown is then marked by the marking arm which may be movably mounted on a support column along which the two locating members are mounted or mounted to the support column by a swivel arm.
