A retaining device for removably securing a dental prosthesis in position. The retaining device includes a male section which can be secured to the side of a fixed tooth and a cooperating female section which can be secured 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 channel member upwardly extending from the housing provides a keyway for receiving a key upwardly extending from the projection, to maintain a secure stability between the male and female sections. 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. |
