Attachment for removably supporting a denture in the mouth of the user

An attachment for removably supporting a denture in the mouth of a user having at least two spaced apart dental posts installed in the users alveolar ridge, comprising:

• an anchor member fittable semi-permanently into the mouth of the user for anchoring, such as by screws, to dental posts, the anchor member being curved to generally the shape of the alveolar ridge of the user and the anchor member having a bar portion extending between spaced apart dental posts, the anchor member having a proximal surface adjacent the user's alveolar ridge and an opposed distal surface;
• a denture member which conforms generally to said anchor member and which is engageable in proximity with said anchor member distal surface, the denture member being castable into a denture having simulated gum portions and teeth portions, said anchor member having retention means and the denture member having retention means which removably interlocks with said anchor member retention means when a denture having said denture member formed thereon is in usable position within the mouth of a user, and the anchor member being of a curved form within a general plane and said denture member being a generally correspondingly curved form within a general plane, said planes being generally parallel to each other when said denture member is formed in a denture and the denture is in position within the mouth of a user, said anchor member retention means being in the form of spaced apart recesses each having an axis inclined at generally the same acute angle relative to said anchor member plane and said denture member retention means being in the form of integrally extending projections removably receivable within said anchor member recesses, each projection having an axis inclined at generally the same acute angle relative to said denture member plane;
• and
• locking means attached to said denture member releasably engageable with said anchor member bar portion and moveable between a locked and an unlocked position, whereby when said locking means is in the unlocked position a denture having said denture member may be inserted into or removed from the mouth of a user.
