Abstract
An attachment for removably supporting a denture in the mouth of the user in which the user has at least two spaced apart dental posts implanted therein, the attachment including a first basic portion in the form of an anchor member semi-permanently attached to the anchor post and being curved to generally the shape of the alveolar ridge of the user and having a bar portion extending between the spaced apart dental posts, the anchor member having retention recesses at each end. The attachment's second basic portion is a denture member which conforms generally to the contour of the anchor member and which is engagable in proximity with the anchor member. The denture member is cast within a denture having simulated gum portions and teeth portions. The denture member has integrally formed projections which are removably insertable into the recesses in the anchor member, the axes of the projections and the axes of the recesses being inclined toward planes of the anchor member and the denture member. The denture member includes an arm pivotal between a locked and an unlocked position. The arm has a blade portion which extends underneath the anchor member so that the arm when in the locked position retains the denture within the mouth of the user. The bar portion is generally circular in cross-section and the projections and recesses are dimensioned to permit limited pivotal movement of the denture member relative to the anchor member when the denture is locked to the anchor member.
