Abstract: The present invention is a precision attachment device for securing a removable dental prosthesis in the mouth, comprising a first section operatively arranged to be secured to a fixed tooth, a second section operatively arranged to be secured within the prosthesis, and also arranged to matingly engage the first section, the second section having a first mating member having a throughbore therein, and also having an elongated casing rotatably disposed within the throughbore of the first mating member; a spring loaded plunger member disposed within the casing and projecting therefrom, and, a retention member within the rotatable casing for limiting the extent of longitudinal travel of the plunger member.

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.
