diamond burs

Bur is dentist consumables used appliances, is a very small needle, the needle from the needle and the needle handle composition, can be inserted into high-speed mobile phone use, to help

Help dentists open cavities, dental scaler repair teeth. If dentists metaphor for handheld rig with a cell phone, then the equivalent of bur drill rig.
Bur, currently divided into tungsten steel burs and diamond burs. Carbide burs which are more commonly used in foreign and domestic, dentists used primarily for diamond bur .
Emery car attached needle Ministry tiny diamond drill peripheral particles, these diamond particles go through the complex, demagnetization, rounded, purification treatment, the sharpness and resistance
Grinding degree with outstanding performance. Diamond bur during use, emery will gradually fall, usually in the diamond drop half the time, the life of this root bur
To an end.
Classification of diamond burs
Classified by function: High-speed, low-speed (16,30,45 jrpm)
Classification by length: standard, short, ultra short-throw (17-26mm)
Classification by weight: coarse, standard, fine, superfine
Grouped by usage: repair abutment preparation, preparation hole type, etc.
By morphological classification: various forms
Emery by category Category: natural and artificial
By Life Category: Disposable, repeatability
The composition of diamond burs
Magic gravel, adhesives, stainless steel handle
The role of the adhesive
1, emery and the dental Endo Box substrate so firmly bonded together.
2, high-quality adhesive surface ensures bur rotating at high speed does not cause turbidity.
3, natural emery and substrate binding is all kinds of abrasive bonded to the substrate, the most difficult and most technical content.
Diamond burs - used several diamond bur
1, the Japanese Shofu
2, the German DFS
3, the Swiss Duracell
4, the United States KEER

what determines the life of diamond burs

Bur, especially diamond bur dental doctor is the most frequently used tools. But because of its relatively low cost, many doctors ignore its maintenance and

Maintenance. And there are many doctors that: "I use *** brand bur, used once and throw away!" The doctor said these words to express the meaning of non-

Often clear that this car has Gutta Percha Points been sterilized needle after grinding cutting ability decreased significantly. What causes this phenomenon it?
     Are summarized as follows:
First, the reasons for sterilization
There are many doctors use a 2% glutaraldehyde for disinfection, you know, glutaraldehyde has some corrosion on the metal, and the disinfection process soaking time than

Long. So there are many doctors complain especially tungsten steel bur bur rust problems.
For steel and tungsten carbide bur is recommended that:
1, autoclavable, for disinfection prior to remain in the blood stains on the bur and tooth tissue debris and timely water rinse, if necessary, use a brush to clean.
2, good quality and bad bur bur sterilized separately to avoid mutual influence
Second, the high-speed impact of the turbine water spray
Because dental chair using a certain time produced a change or anthropogenic causes water becomes smaller. At this point bur rotating at high speed process can not be effectively cooled, would produce a certain

Was loss.
Recommends regular inspection of water meets 50 ml / min standard
Third, the choice of bur
You doctor should pay attention to the difference in the consumer's selection of diamond bur is synthetic or natural diamond emery. The difference between them is that the former will

Decreased cutting force there dental scaler grinding abrasion resistance of the latter is relatively long.
 
The above is a synthetic diamond micro-graph, edges relatively simple, polished edges after cutting ability has decreased significantly. Synthetic diamond bur lower cost in the market

The sales price is relatively uniform, no matter what form the thickness of both a price.

how to choose the dental chair

First, the basic method of selection of the dental chair

    1: dental chair price is a primary consideration. How to spend less and it can guarantee the quality of the dental chair?

This dental chair prices low, but denture teeth poor durability. If you are a business volume also dental clinic, or the main consideration electric dental chair.
    What is a pneumatic hydraulic type dental chair it? Pneumatic dental chair refers to gas film control handset operation, the main features are disc foot switch to control the chair position with hydraulic

Exercise, hydraulic pumps and hydraulic pipes. Why is it less durable, mainly with the electronically controlled motor-type dental unit of comparison. Electrically controlled solenoid means

Valve control handset operation, the main feature is a versatile electric foot switch or foot switch, the motor is a motor control chair position movements.
    European production of dental chair chair position is mainly motor control action, open the seat backrest can see the control action of the small motor. So when do you expect the volume of business

Large, as far as possible choose this dental chair, it is more durable, but the price is relatively high.
    Of course, now more and more dental clinics are used as the main electric dental chair dental equipment.

    2: After selecting the dental chair models, depending on configuration suitable to themselves. If you are an oral physician, and less than strong suction, you can dispense with strong suction (if

Strong suction is not optional but standard time). In fact, the two phones is a luxury configuration, you can view a decrease in demand.

    3: identification of dental dental scaler treatment machine quality quality, but also observed from the following aspects.
    First, look at the appearance of the machine, to see whether the combination of tight junction shell, if the gap is large, show quality, but off.
    Then take a look at the finish of metal parts and machining precision metal parts here mainly refers to three with a gun and a cell phone sleeve, if they are very rough, Table

Ming poor quality. Finally, open the shell observed cardiac chair position control: motor or pump.



    Second, the method of selection of professional dental chairs
