Abstract
A retaining device for removably securing a dental prosthesis in position, having a fixed male section for securement to the side of a fixed tooth and a cooperating free female section for securement within the dental prosthesis. The male section includes a projection which is received in an inverted U-shaped housing at the forward end of the female section. A spring loaded plunger member positioned within the female section extends into the housing and engages a recess formed in the projection thereby locking the two sections together. A jig is provided for suitably placing spaced apart male sections in alignment and in proper parallel relationship.
