Abstract
Abstract An attachment for pivotally supporting a denture in the mouth of the user in which the user has at least two spaced apart dental posts implanted therein, such posts being in the front of and one to either side of the front center of the mouth of the user, the attachment including an anchor member semi-permanently attached to the anchor posts and having a bar portion extending between the spaced apart dental posts. A denture member which conforms generally to the contour of the anchor member is engagable in proximity with the anchor member bar portion. The denture member is cast within a denture having simulated gum portions and teeth portions. The denture member has an arm for removably and pivotally interlocking the denture member with the anchor member bar portion when a denture having the denture member formed therein is in a usable position within the mouth of the user. Pivotation limiting trunnions are formed as a part of the anchor member. The trunnions serve to limit the angle of pivotation of the denture member relative to the anchor member.

An attachment for removably supporting a denture in the mouth of a user having at least two spaced apart dental posts installed in the user's alveolar ridge, such two posts being in the front of, and one to each side of, the center of the mouth of the user, the attachment comprising: an anchor member fitable into the mouth of the user for attachment such as by screws to two spaced apart posts in the front of the mouth of the user, the anchor member having a bar portion extending between the two spaced apart posts; a denture member which conforms generally to the anchor member and is engagable in proximity with said anchor member bar portion, the denture member being castable into a denture having simulated gum portions and teeth portions; locking means of removably and pivotally interlocking said denture member with said anchor member bar portion when a denture having said denture member formed therein is in usable position with the mouth of the user; and pivotation limiting means formed as a part of said anchor member and said denture member limiting the angle of pivotation in one direction of said denture member to said anchor member about said bar portion when said denture member is interlocked with said anchor member.
Claim 3
Dependent Claim
40 words
An attachment member according to claim 1 wherein said anchor member bar portion is elongated and has a longitudinal axis and wherein said bar portion is at least in part substantially circular in a plane taken perpendicular said longitudinal axis.
Claim 4
Dependent Claim
105 words
An attachment member according to claim 1 wherein said locking means is in the form of an arm having a first and a second end, and having the first end pivoted to said denture member whereby the arm is pivotal between a locked and an unlocked position, the arm having adjacent the second end a blade portion, and having at the second end fingernail engaging means whereby the second end may be engaged by the fingernail of the user to pivot the arm to the unlocked position, the blade portion engaging said anchor member bar portion when said arm is pivoted to the locked position.
Claim 5
Dependent Claim
49 words
An attachment member according to claim 1 wherein said pivotation limiting means includes: trunnion means extending from said anchor member; and interceptor means extending from said denture member which engage said trunnion means when said denture means has been pivoted a predetermined angle about said anchor member bar portion.
Claim 6
Dependent Claim
39 words
An attachment according to claim 1 wherein said pivotation limitation means includes means limiting the pivotation of said denture member about said anchor member bar portion in one direction, but which does not limit pivotation in the opposite direction.
Claim 7
Dependent Claim
51 words
An attachment according to claim 5 wherein said pivotation limitation means includes means limiting the pivotation of said denture member in the direction towards the front of the mouth of the user, but which does not limit pivotation in the direction away from the front of the mouth of the user.
