ABSTRACT:
Connecting apparatus for removable dental prostheses comprises a frustoconical male element attached to a base and including a cylindrical transverse groove and an oblique groove. A female part is essentially composed of a block having a frustoconical cavity matching the male element so that the female part can be fitted over the male element. A tubular sleeve accommodates a sliding member which is biased axially by a spring held in place by a cap screwed on one end of the sleeve. A tip attached to a threaded section at the end of the sliding member remote from the spring makes it possible to displace the sliding member axially against the bias of the spring. When the block is fitted over the male element, a section of the sliding member is caught by the edge of the oblique groove and moved axially, then enters the transverse groove, thereby interlocking the male element and the female part.
