ABSTRACT:
The invention concerns a snugly fitting denture such as bridges and the like, consisting of a metallic foundation and of a ceramic facing shell as well as a process to its manufacture. It is the object of this invention to develop a compact system for a snugly fitting denture with high firmness and mechanical loading capacity as well as with prolonged durability under the conditions prevailing in the oral cavity. This is achieved by the fact that the metallic foundation consists of a base metal alloy with a silane-content of .ltoreq.0.5% and that the ceramic facing shell is provided with a silicon-coupled adhesive plastic part. The metal base is silanized in an ultrasound bath, highly fluid prosthesis plastic is applied to its labial aspect and the facing shell is pressed-on. Thus a solid chemical bonding develops between foundation and facing shell. This compact system is without slits and does not offer any possibilities of aggression to harmful influences existing in the milieu of the oral cavity.
