Abstract
One or more specific embodiments disclosed herein includes a dental apparatus comprising a prosthesis, an implant fixture, a multi-unit abutment comprising a clocked projection and a conic section, and an adjustable locking device. The adjustable locking device may comprise a washer, a first pyramidal element, plurality of expansion segments each comprising a plurality of bottom planar surfaces and a plurality of top planar surfaces, a second pyramidal element comprising a second plurality of angled planar surfaces and a convex upper surface, a central retaining screw that threadingly engages the multi-unit abutment, and an O-ring, wherein the O-ring engages each of the plurality of expansion segments.
Claims13
A dental apparatus, comprising:
- a prosthesis;
- an implant fixture, wherein the implant fixture comprises a recess;
- a multi-unit abutment comprising a clocked projection and a conic section, wherein the clocked projection engages the recess of the implant fixture;
- and
- an adjustable locking device, comprising:
- a washer comprising a tapered interior and a concave upper surface, wherein the tapered interior engages the conic section of the multi-unit abutment;
- a first pyramidal element comprising a convex lower surface and a first plurality of angled planar surfaces, wherein the convex lower surface engages the concave upper surface of the washer;
- a plurality of expansion segments each comprising a plurality of bottom planar surfaces and a plurality of top planar surfaces, wherein each of the plurality of bottom planar surfaces engages at least one of the first plurality of angled planar surfaces of the first pyramidal element;
- a second pyramidal element comprising a second plurality of angled planar surfaces and a convex upper surface, wherein each of the second plurality of angled planar surfaces engages at least one of the plurality of top planar surfaces of at least one of the plurality of expansion segments;
- a central retaining screw that threadingly engages the multi-unit abutment;
- and
- an O-ring, wherein the O-ring engages each of the plurality of expansion segments.
An adjustable locking device, comprising:
- a washer comprising a tapered interior and a concave upper surface;
- a first pyramidal element comprising a convex lower surface and a first plurality of angled planar surfaces, wherein the convex lower surface engages the concave upper surface of the washer;
- a plurality of expansion segments each comprising a plurality of bottom planar surfaces and a plurality of top planar surfaces, wherein each of the plurality of bottom planar surfaces engages at least one of the first plurality of angled planar surfaces of the first pyramidal element;
- a second pyramidal element comprising a second plurality of angled planar surfaces and a convex upper surface, wherein each of the second plurality of angled planar surfaces engages at least one of the plurality of top planar surfaces of at least one of the plurality of expansion segments;
- a central retaining screw;
- and
- an O-ring, wherein the O-ring engages each of the plurality of expansion segments.
