Abstract
An improved denture system is disclosed. An improved denture system has a support bar and an artificial denture base. The denture base has an oversize cutout and a corresponding cavity and the support bar has a plurality of reference posts which mechanically interface with the corresponding cavity so that the support bar is connected to the artificial denture base and provides reinforcement and stability to the denture system. The shape and position of the reference posts fully constrains the support bar in a fixed position with reference to the denture base. In one embodiment, the denture base snap-fits onto the support bar.
Claims19
An improved denture system comprising:
- a curved support bar comprising:
- at least one reference post;
- at least one implant interface;
- and
- a denture base comprising:
- an oversize cutout comprising a unitary channel extending an entire length of said curved support bar and wherein said curved support bar may be placed and wherein said curved support bar only rests against the at least one reference post and not against the oversize cutout;
- at least one corresponding cavity wherein said at least one reference post may be inserted, wherein said corresponding cavity extends farther into said denture base than said oversize cutout;
- and
- wherein at least a portion of said reference post is fixed in said corresponding cavity by at least one of:
- screw fasteners, press fitting, snap fitting, and embedding in said denture base,
- whereby said support bar is maintained in substantially fixed communication with said denture base to secure said denture base.
A method for providing positioning of a support bar within a denture system, said method comprising:
- providing a curved support bar comprising:
- at least one reference post;
- at least one implant interface;
- providing an improved denture base comprising:
- an oversize cutout comprising a unitary channel extending an entire length of said curved support bar and wherein said curved support bar may be placed, wherein said curved support bar only rests against the at least one reference post and not against the oversize cutout;
- at least one corresponding cavity wherein said at least one reference post may be inserted, wherein said corresponding cavity extends farther into said denture base than said oversize cutout;
- and
- interfacing at least a portion of said reference post in said corresponding cavity by at least one of:
- screw fasteners, press fitting, snap fitting, and embedding in said denture base such that said support bar is maintained in substantially fixed communication with said denture base to secure said denture base.
A support system comprising:
- a bar comprising a single curved segment configured to follow a contour of a patient's edentulous ridge;
- a plurality of reference posts extending from the bar and configured to extend into corresponding cavities of a denture base for securement by at least one of:
- screw fasteners, press fitting, snap fitting, and embedding;
- a plurality of implant interfaces disposed along the length of the bar and configured to connect to implants;
- wherein the support system is configured to rest in at least one oversize cutout of a denture base forming unitary channel extending an entire length of said support bar to secure said denture base,
- wherein the curved support bar is configured to only rest against the plurality of reference posts and not rest against the oversize cutout;
- wherein the reference posts configured to extend into corresponding cavities are configured to extend in to corresponding cavities that extend farther into the denture base than the oversize cutout, and
- wherein the support bar is configured to be fully constrained by the interfacing of the reference posts and corresponding cavities whereby the support bar is configured to position a denture base in unique fixed position fully constrained relative to the support system.
