Abstract
A dental polishing cup for holding a dental treatment material, having a body with an elastic material, the body having a length along a longitudinal axis, a proximal end, a distal end, and a round cross-section taken perpendicularly to the length, wherein the body has a distal diameter at the distal end, the body further defining a cup cavity with an opening at the distal end; and wherein a portion of the body defines an enhanced-flexibility band (EFB) situated circumferentially at a distance from the distal end, the EFB formed from a material that is more flexible than other portions of the body, and the distal diameter of the cup cavity expands in response to an applied pressure to the distal end.
Claims26
A dental polishing cup for holding a dental treatment material, the polishing cup comprising:
- a body comprising an elastic material, the body having a length along a longitudinal axis, a proximal end, a distal end, and a round cross-section taken perpendicularly to the length, wherein the body has a distal diameter at the distal end, the body further defining a cup cavity with an opening at the distal end;
- and
- wherein a portion of the body defines an enhanced-flexibility band (EFB) situated circumferentially at a distance from the distal end, the EFB formed from a material that is more flexible than other portions of the body, and the distal diameter of the cup cavity expands in response to an applied pressure to the distal end.
A dental polishing cup for holding a dental treatment material, the polishing cup comprising:
- a body formed of an elastic material and having a length along a longitudinal axis, a proximal end, a distal end with a distal diameter, a round cross-section taken perpendicularly to the length, the body comprising:
- the proximal portion comprised of a material having a first hardness, and a flare portion at the distal end, the flare portion defining a cup cavity with an opening at the distal end,
- wherein the flare portion is formed of a material having a second hardness less than the first hardness;
- and the flare portion expands in response to an applied pressure to the distal end.
A dental polishing cup for holding a dental treatment material, the polishing cup comprising:
- a body comprising an elastic material, the body having a length along a longitudinal axis, a proximal end, a distal end, and a round cross-section taken perpendicularly to the length, wherein the body has a distal diameter at the distal end, the body further defining a cup cavity with an opening at the distal end;
- and
- wherein a portion of the body defines an enhanced-flexibility band (EFB) situated circumferentially at a distance from the distal end, the EFB having a first material property that is more flexible than one or more portions of the body, and the distal diameter of the cup cavity expands in response to an applied pressure to the distal end.
A dental polishing cup for holding a dental treatment material, the polishing cup comprising:
- a body formed of an elastic material and having a length along a longitudinal axis, a proximal end, a distal end with a distal diameter, a round cross-section taken perpendicularly to the length, the body comprising:
- the proximal portion comprised of a first material having a first material property, and
- a flare portion at the distal end, the flare portion defining a cup cavity with an opening at the distal end,
- wherein the flare portion has a second material property different from the first material property;
- and the flare portion expands in response to an applied pressure to the distal end.
A dental polishing cup for holding a dental treatment material, the polishing cup comprising:
- a body comprising an elastic material, the body having a length along a longitudinal axis, a proximal end, a distal end, and a round cross-section taken perpendicularly to the length, wherein the body has a distal diameter at the distal end, the body further defining a cup cavity with an opening at the distal end;
- wherein the body further comprises:
- a first portion adjacent the distal end having a first outer diameter;
- a second portion situated proximally relative to the first portion, the second portion having a second outer diameter that is reduced relative to the first outer diameter;
- and
- a third portion situated proximally relative to the second portion and adjacent the proximal end, the third portion having a third outer diameter that is increased relative to the second outer diameter;
- wherein the second portion defines an enhanced-flexibility band (EFB) situated circumferentially at a distance from the distal end that is less than a distance from the proximal end;
- and
- wherein the distal diameter of the cup cavity expands in response to an applied pressure to the distal end.
