You do not know the dental burs, Hanzhong Rui Xin

Dental bur is a very strange term for many people, but for the professional department of Stomatology physicians, which is essential to their daily work, dental bur quality largely determines the success of their dental care.

So what exactly is the dental needle? Come down from Hanzhoung Rui Xin (a company specializing in the production of dental needle business) to tell you.

Dental bur is Department of Stomatology Physicians clinical medical dental drill grinding, grinding rotary tool finishing department of Stomatology technicians using dental restorations.
Composition of dental needle:
The dental needle is composed of a working part and a handle.
Two. Classification of dental needle
1, according to the use of points: dental needle according to the purpose of the clinical application of the needle into the dentist, dental technician room technician needle.
2, according to the material: dental bur from material is divided into steel needle, tungsten steel needle, diamond bur, ceramic needle.
3, according to the speed points: divided into high speed dental needle, low speed dental needle two.
4, according to the Ministry of work form: commonly used ball drill, drill crack, inverted cone drill, ball head split drill (broken crown car, wheel type drill needle).
5, according to the work of edge tooth shape: flat blade, serrated edge (file pattern).
Three, high speed dental bur will enter a short tooth contact with blood, body fluids in use, belonging to two types of medical equipment supervision, need to be submitted to the relevant departments of the state registration (Hanzhoung Ruixin certificates); low speed dental bur strictly should belong to a class of medical equipment supervision.
Four, dental bur basic standard: standard high speed dental bur length is 19 mm, shank diameter 1.6 mm; standard low bending machine needle length of 22 mm, shank diameter 2.35 mm; low standard straight handle needle length of 44 mM, 2.35 mm diameter shank.
Five, high speed dental bur made of steel or steel manufacturing, the hardness and strength of steel is low, not easy processing precision edge teeth, now there is little steel high speed dental car top city, now in the market is mainly tungsten high speed dental bur.
At present domestic dentists for diamond bur and tungsten dental bur, foreign dentists mainly use carbide burs, rarely used high-speed diamond bur.

The car is using a sharp tungsten needle cutting edge tooth or teeth restoration, smooth cutting surface scratches; high hardness tungsten steel sharp, durable, high cutting efficiency, good cutting quality.

Diamond bur is the use of hard tooth restorations or emery grit grinding, grinding surface scratches; emery grit is attached to the stainless steel substrate, when grinding with diamond sand shedding, sharpness, durability, grinding efficiency, the quality is not high.
Before the domestic dental burs mainly imported tungsten steel cutting tools, only a few manufacturers in accordance with the industry standard production part of dental tungsten steel bur, there are several high technology (Hanzhoung Rui Xin is one of them), precision CNC machine tool manufacturers domestic dental tungsten steel needle, Department of Stomatology physicians to make more use of the near future on the quality of domestic tungsten dental bur.
