Device for the releasable fastening of a partial denture on a crown or another counter-part of the residual teeth

摘要

The invention proposes a device for the releasable fastening of a partial denture, in which a locking bolt 22 located in a bolt housing on the denture side interacts in a releasably locking manner with a counter-element 11 on the crown side through a perforation in the bolt housing and in which there is an auxiliary housing 21' which surrounds the bolt housing and is preferably made of a plastic that incinerates without residues for formation of a receptacle for the bolt housing on the denture side. At the same time, the auxiliary housing 21' fitted with a perforation is sealed at one end and can be attached to the male part 11 of a T-shaped attachment or the like of the crown, connecting the crown 1 to the partial denture, in the region of a groove 12 forming the counter-element and arranged at right angles relative to the assembly direction of the attachment, so that the locking bolt 22 engages lockingly into the groove 12. <IMAGE>
