A shank portion is pivotally coupled to a head portion at one end thereof and a rear portion covers the opposite end thereof. The head portion is adapted to be coupled to an attachment for existing teeth, while the rear portion is adapted to be coupled to a case which fits over the mouth ridges and supports artificial teeth. The head portion includes free ends which can be distorted to provide a tight fit against the shank portion and prevent lateral movement of the shank portion with respect to the head portion.
