ABSTRACT:
A denture adapted to be locked in place in the mouth which includes the provision of two spaced-apart implanted pins in the gum with the pins being exposed and mounting spherical heads, each adapted to receive a rigid frusto-spherical seat member which is aligned and located in the artificial gum material of a denture such that the denture can be nested on the implant structure. The two implants and seat members have a locking device in the form of a sliding plunger extending tangentially to the frusto-spherical surfaces and a bore provided therein for interfering with the head of the implant when locked.
