Embodiment 1

[0033] A method for preparing a high-strength dental bur. The dental bur is made of tungsten steel alloy and integrally formed, that is, the base of the dental bur is an integral needle body, which is directly cut into a blade head. Then, the base body of the dental bur was subjected to the following surface treatment.

[0034] Specific surface treatment steps:

[0035] (1) Clean the dental bur matrix, degrease and degrease, and dry;

[0036] (2) Mix alloy penetrating agent and wear-resistant activator at a mass ratio of 1:3, disperse ultrasonically in absolute ethanol for 20 minutes, and use a spray gun to evenly spray on the base of the dental bur to control the coating thickness to 2 μm;

[0037] The alloy penetrating agent is formed by mixing iron boride, vanadium pentoxide and chromium sesquioxide at a mass ratio of 1:3:3, and the particle diameter is 50nm. The wear-resistant activator is formed by mixing silicon carbide and silicon nitride at a mass ratio of 1:1, and ...

Embodiment 2

[0041] The difference from Example 1 is that the alloy penetrating agent is made by mixing vanadium pentoxide and chromium trioxide at a mass ratio of 1:1, and the particle size is 50nm.

Embodiment 3

[0043] The difference from Example 1 is that the alloy penetrating agent is made by mixing iron boride and vanadium pentoxide at a mass ratio of 1:6, and the particle size is 50nm.

Abstract

The invention discloses a high-strength dental drill and a manufacturing method thereof. The manufacturing method for the high-strength dental drill comprises a step of performing surface treatment onan integrally formed dental drill base body made of a tungsten steel alloy. The high-strength dental drill disclosed by the invention is high in surface hardness, is extremely high in concentricity,is free of swing, is stable in rotation, is high in cutting speed, is less in generated heat, reduces damages on dental pulp and tooth tissues, reduces labor intensity of a dentist, and effectively improves comfort level and degree of satisfaction of a patient. The high-strength dental drill is used for cutting a tooth, so that the surface of the tooth is smooth and free of scratches after a holeis drilled. Moreover, the high-strength dental drill is low in production cost, is suitable for effectively popularizing a concept that one drill is specially used for one person in dental outpatientservice, and effectively solves the cross infection problem.

Description

technical field [0001] The invention relates to a bur and a preparation method thereof, in particular to a high-strength dental bur and a preparation method thereof. Background technique [0002] Dentistry, one of the classifications of medical disciplines, is generally incorporated into the Department of Stomatology in large hospitals. Dentistry mainly treats diseases related to teeth and periodontium. [0003] Commonly known as caries and tooth decay, caries is a bacterial disease, which can be secondary to pulpitis and periapical periodontitis, and even cause alveolar bone and jaw inflammation. If it is not treated in time, the lesion will continue to develop, forming cavities, and eventually the crown will be completely destroyed and disappeared. The final result of its development is tooth loss. Caries is characterized by high incidence and wide distribution. It is the main common disease of the oral cavity and one of the most common diseases of human beings. The Wor...
