ABSTRACT:
A superstructure for an artificial tooth is formed of a a root post which is screwed into a root canal of a tooth stump. The root post includes a cylindrical tap having a cutting thread, and is capable of guiding a sleeve-shaped rose cutter having a curved cutting surface to produce a tooth recess with a lower curved portion. The tooth recess is concentric with respect to the root post. A sleeve-shaped crown anchor is concentrically secured to the root post and has a lower curved portion which fits into and corresponds with the lower curved portion of the recess. The artificial tooth is secured on the crown anchor.
