Dental diamond bur

Abstract

The invention discloses a dental diamond bur, which comprises a bur handle, a bur neck portion and a working bur tip, wherein the surface of the working bur tip is plated with a layer of a diamond abrasive material, the working bur tip and the bur neck portion are fixedly welded, a projecting baffle is fixed at the welding fixation connection position, the projecting baffle plane is perpendicular to the axis of the working bur tip, the diameter of the projecting baffle is larger than the maximum diameter of the working bur tip, the bur neck portion and the bur handle form a threaded connection, an identification code is fixed on the bur neck portion, and the color of the identification code is corresponding to the grain size of the diamond abrasive material. According to the present invention, the projecting baffle controls the longitudinal depth in the tooth articulation direction so as to reduce the discomfort and the pain of the patient, shorten the treatment time, and provide advantages of convenient operation and harmlessness to human body; only the working bur tip and the bur neck portion are required to be changed when different specifications of the diamond burs are selected and the same bur handle is shared so as to reduce the production material and the production cost; and through the anti-slip pattern, the handheld action is stable, and the slipping can be reduced.

Description

technical field [0001] The invention relates to a dental instrument, in particular to a dental diamond bur. Background technique [0002] Diamond bur is a kind of dental instrument with a certain cutting ability, which is made by adhering or electroplating the diamond abrasive with a certain acute angle with the central axis of the stainless steel bur as the center of the circle according to a certain direction and spacing. Since the tooth surface is a layer of hard enamel with a Mohs hardness of 6-7, only diamond can efficiently grind enamel. The diamond bur includes a stainless steel bur shank, a bur neck and a tip coated with diamond abrasive. Diamond burs have a variety of shapes and structures. Diamond burs of different specifications have different shapes of needle tips, and the diameters of diamond abrasive grains on the needle tips are also different. Clinically, due to individual differences in patients, different tooth positions, and different proposed restoratio...

Problems solved by technology

When dentists use burs to locate the depth of teeth in the occlusal direction, they mostly rely on experience. If the grinding depth is too deep, it is easy to damage the tooth nerve, causing discomfort and pain to the patient; if the grinding depth is too shallow, repeated grinding is required to prolong the treatment. time
