Abstract: The device which is adapted to be secured between two existing teeth is suitable for supporting an artificial denture to replace an anterior tooth or a posterior tooth. The device is comprised of a backing member having two complimentary parts which are mounted for sliding movement relative to each other. Each part is provided with a laterally extending projection adapted to be located in a groove in the side of an adjacent real tooth whereby upon sliding movement of the two parts, the distance between the ends of the projections can be shortened to allow placement of the device between two existing teeth. The two parts can then be slid relative to each other to extend the projections into the grooves in two spaced apart real teeth. A threaded clamping member is then tightened to secure the two parts against relative movement with respect to each other and a facing member is secured to the backing member.

Abstract: The device which is adapted to be secured between two existing teeth is suitable for supporting an artificial denture to replace an anterior tooth or a posterior tooth. The device is comprised of a backing member having a pair of parallel extendable arms slidably disposed in grooves in said backing member on opposite sides of a pinion rotatably mounted in said backing member in simultaneous meshing engagement with teeth on both arms for simultaneously extending both arms in opposite directions upon rotation of said pinion in one direction. The extended end of each arm is adapted to be disposed in a precut groove in an existing tooth to support the device between two existing teeth. Suitable projections are provided on the surface of the backing member for cooperation with complimentary grooves in the artificial facing. The facing is secured to the backing and the extended arms are secured in the grooves of adjacent teeth by a suitable cement or filling material.
