How to choose a dental scaler

ultrasonic scaler on the market today is a common used oral special dental equipment. In principle, it is more scientific and reasonable than the old-fashioned pneumatic scaler, and the efficiency and safety has also been greatly improved. Although popular scalers on the market today are large and ever-changing varieties, but the basic composition can be divided into several large pieces, include voltage amplification part of the shock generator, transducer, and the work of the first control signal.
Although there is wide range of powerful dental scaler on the market, but the problem is still plagued with a lot of dentists, include the following aspects: ultrasonic scaler tip selection, power and frequency selection, water supply options, and so on.
1. The tip of the options: First, consider the material; In general, the hardness of the material should not be greater than the hardness of enamel. Some patients often complain of discomfort after cleaning teeth, chewing difficulties arise with pain worse sense, partly because of gingival recession or root exposure does not cause teeth cleaning techniques, and partly because the reasons for the tip finish. Secondly, from the use of consideration should be in accordance with the provisions of scaler manufacturers, dental cleaning different positions and different purpose to select the appropriate treatment of the tip. Another work scaler tip angle of the work should be based on zero line of the face 30 degrees to 70 degrees, can not work in the direction perpendicular to the face; otherwise it will damage or break the tip. Use the tip of the site should be the side of the front. Finally, it should be noted that wear or deformation of the work of fracture of the scaler tip should immediately stop using.
2. Power and frequency selection: the highest frequency scaler is about 30000 Hz, (Bollywood produced scaler operating frequency is 25000-32000 Hz) higher frequency of the power output is not more benefits, it will bring unnecessary heat loss; general, scaler according to installation can be divided into built-in (i.e.: integrated and comprehensive treatment units) and external (i.e.: as a separate unit); built-in power generally 10-15 watts output, external power output is generally 40-50 watts, which is not to say power, like teeth cleaning effect. Choose the right job tip, operating frequency (power), using the correct technique is cleaning teeth cleaning teeth key to success. Some operators use the scaler in the process will find the power shortage, can not be blamed this time is not enough power scaler, but should start checking the following aspects: first, whether the tip scaler on tight? Scaler work there is an obvious tip wear; if so should tighten or replace the tip of the tip. Second, the handle connections are tight, is leaking; if so, should be re-connected the handle. Again, check the power conditioning files in the correct location (Note: In general the best place to power file is not 100%, but 50% - 75%). Finally, check whether the factory power quality requirements. If these reasons are not, they should contact the manufacturers of.
3 of water supply options: scaler can generally be divided into the water supply filtered water to use for the scaler; separation of pure water bottle (with a peristaltic pump) water; pressure bottle water in three forms. Among them, the second, the third most popular way.
Although, on the scaler on the market new technologies, new materials are emerging, such as fiber optic scaler, titanium handle, overload power protection, thermal protection, such as sandblasting scaler, but the use of scaler same purpose . In short, the dentist use a ultrasonic scaler, in addition to considering the unit's actual needs and economic capability, but also note the following:
1 manufacturers have a complete technical information, installation instructions and operating instructions.
(2) Manufacturers have a full after-sale service system. Thus, you will not have to worry about after the purchase.
