ABSTRACT:
The invention concerns a dental crown, with a facing for example on the visible side for example, and a rigid connector for receiving the crown. The respective cooperating walls telescope for securing the removable prosthesis. The crown is secured to a stump left in the jaw. It has a lingual functional surface with a supragingival cervical offset, a supporting surface adjacent to the prosthesis saddle, and an intracoronal channel extending across the crown more or less parallel to the lingual functional surface. The rigid connector has three friction cylinders, a lingual outer wall which is between the first and second friction cylinder, a supporting telescope wall with the saddle for the prosthesis secured to it, and a patrix web which is inserted in the intracoronal channel. The outer telescope wall, supporting telescope wall, and patrix web of the connector completely surround a web on the crown. The satisfactory hold between the components of the prosthesis derives primarily from friction between their facing parallel walls, for which the friction cylinders and closed-telescope structure are primarily responsible.
