The invention relates to a coated abrasive tool including a carrier which has a carrier material and including an abrasive surface coating on a surface region of the carrier. The abrasive surface coating has abrasive functional particles and a thermoplastic binder for an adhesive connection between at least some of the abrasive functional particles and the carrier material. At least some of the abrasive functional particles on the surface region of the carrier are partly integrated into the carrier material and are connected to the carrier material, and at least some of the abrasive functional particles on the surface region of the carrier are additionally partly integrated into the thermoplastic binder, the thermoplastic binder being connected to the abrasive functional particles and the carrier material.

A lathe adaptor assembly for mounting at least one polishing wheel to a spindle of a dental lathe. The lathe adaptor assembly comprises a first retention bolt with a hollow interior, a hollow bolt head, a reinforced internal structure, and an exteriorly-threaded end for engaging the spindle to secure the lathe adaptor assembly, a second retention bolt also featuring a hollow interior and an exteriorly-threaded end, and a center carrier equipped with a central throughbore designed to mount a first polishing wheel and a second polishing wheel, each secured by friction to prevent rotation on the center carrier.

A tool for interproximal reduction includes a handpiece and a substantially solid disk-shaped member. The hand tool has a motor coupled to a coupling member. The handpiece is for creating oscillating motion in an oscillation range of 90 degrees or less. The disk-shaped member has a front face and a rear face and defines two or more segments that are different from one another. Each segment has different properties comprising one or more of perforations, cutting surfaces, and abrasives. The disk-shaped member has a centrally disposed aperture for coupling to the handpiece with the coupling member. The properties only partially cover one or more of the front or rear face of the disk. The handpiece is configured to permit a user to position their fingers directly adjacent the dish-shaped member during operation of the handpiece.

A dental separator ring for use in a dental restoration procedure in a mouth of a patient. The dental separator ring includes a first arm, a second arm, a central portion coupled to both the first arm and the second arm, a first pad coupled to the first arm, the first pad adapted to be positioned on a lingual side of adjacent teeth in the mouth of the patient, and a second pad coupled to the second arm, the second pad adapted to be positioned on a buccal side of the adjacent teeth in the mouth of the patient. The first pad has a first profile and the second pad has a second profile different from the first profile.

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.
