<p>The component has a protecting region (533) radially surrounding entire or a part of an operation head of a threaded pin in a water-tight manner such that axial length of the operation head does not exceed axially the protecting region. The threaded pin is anchored by screwing in a tooth root. The protecting region is integrated with a support element (53) e.g. single-piece threaded stub, that is anchored by screwing in the root. An external support surface of the support element receives a coronary component or forms the coronary component of a dental joint prosthesis. Independent claims are also included for the following: (1) a dental joint prosthesis (2) a drill bit or material removal tool for preparing a tooth root, for installation of a prosthesis component (3) a method for realization of a prosthesis component.</p> |
