A prophylaxis angle that is configured to be attached to and operated by a powered dental handpiece. The prophylaxis angle includes a cup having a first end and a second end. The first end is couplable to the dental handpiece and at least one projection is at the second end of the cup.

An object of the present invention is to provide a dental polishing instrument that causes no clogging, that prevents occurrence of any secondary flaw, that is excellent in the polishing property, and that can provide high gloss in a short time period, for a dental prosthetic appliance difficult to polish. Another object thereof is to provide a dental polishing instrument that enables easy discharge of polishing sludge while that simultaneously shows sufficient strength. A dental polishing instrument according to the present invention can suppress clogging and occurrence of any secondary flaw due to the polishing sludge and can efficiently polish by forming a polishing abrasive grain layer including polishing abrasive grains and a resin material, into protrusions on the surface of a base material thereof and by disposing the protrusions on the base material.

A removable dental mandrel guard comprising a collar portion extending from a first open end to a transition region, which may include a first tapered portion, the transition region reducing from a first to a second interior diameter; a shaft guard extending from a first end rigidly connected to the transition region to a second end rigidly connected to the disc shield and having interior cross section defining the second interior diameter; a disc shield having opposed first and second transverse walls, each with a partially enclosed perimeter edge joined by coextensive edge wall extending from a first edge point to a second edge point, the interiors of the first and second transverse walls and edge wall defining a disc cavity; a continuous open seam extending longitudinally from the collar portion first open end to the shaft guard second end.

The present disclosure relates to a dental finishing strip that includes an abrasive protrusion. The disclosed device can be utilized in dental restorations of interproximal cavities. The abrasive finishing strip with abrasive protrusion can remove sharp enamel edges at the proximal surface of the tooth and assist in forming a desired beveled edge at the proximal surface. Such beveled edges are conventionally difficult to form along preparation edges associated with the proximal surface of the target tooth. A beveled margin results in an improved sealing of the composite resin to the treated tooth, which in turn can increase a composite dental filling's longevity.

A dental instrument includes a head (2) having cutting edges (1) and made of a ceramic material, and a shaft (3) which can be clamped into a driving member and is made of a metal material. The head (2) includes a mounting plug (4) having an external thread (5) and the shaft (3) includes a front-side threaded recess (6) into which the mounting plug (4) can be screwed. At least one locking recess is formed between the mounting plug (4) and the threaded recess (6).

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.
