can be used over long teeth

How long can mend teeth?

We know that the teeth rotten hole on the back as soon as possible to the hospital for treatment (fillings). Dental health supplement can be used exactly how long, this is the most concerned about the patient, but also a more complicated issue. Teeth repaired after a short period, and how the function, with a variety of factors. denture teeth The first is timing fillings, ie when the patient visits the extent of dental caries. Location and shape of cavities have a great relationship. Followed by the filling materials, different materials and the bond of cavities vary. Furthermore, that dental cavities before processing. If only carious cavities and the cavity is good, shallow, and not adjacent surfaces of teeth, etc., are only required to clean and remove tooth decay cave organize, prepare cavity, thorough disinfection, with permanent dental materials the cavities were filled. Such a good complement of teeth should be used for life. When the dental pulp or apical lesions reached, as long as thoroughly anti-inflammatory treatment, and finally achieve tight filling, but also can be lifelong. But if severely damaged teeth, tooth hole is too large, too deep, irregular shape, or proximal hole type, then filled with good teeth should be used with caution. Otherwise, biting hard objects prone to splitting or dental fillings fall off. Especially kills nerve or pulp necrosis teeth without a blood supply, the teeth become brittle, so anti-inflammatory teeth after filling, biting hard objects it more likely to cause tooth splitting, filling off, resulting filling failure; even teeth completely split split into the following gums, often leading to tooth extraction. Thus, the success of the dental patient and doctor relationship dental instruments between the two are very closely related. First, the doctor fillings should be strictly and carefully press the formal procedures to operate, and the patient should also be early detection and early dental treatment, filling a good fight in the early carious teeth, to achieve the best results.

the financial crisis on the impact of the medical device industry

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?
    First, the volume of business you expect to see much, if you expect the volume of business is very small, the budget is not large, it is recommended that you buy a pneumatic hydraulic type 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

    Able for the above judgment to show that you have mastered the basic method of selecting the dental chair. Here is more from the perspective of how to choose a professional dental chair.
