Dental High-Speed
handpiece (Dental High-Speed Handpiece) Professional Guide
1.Parameters
RPM: 300,000~400,000 RPM some implant handpieces can reach 500,000 RPM, torque: about 1.5~2.5 Ncm, Dental High-Speed Handpieces rely on the sharpness of the needle to cut at high speeds, non-powerful operation, collet type: ISO 1797 standard 1.6mm needles, weight: 60~100g this kind of specific gravity design can reduce the fatigue of the doctor, the noise: ≤65dB, cooling mode: aerosol/water mist dual channel, adjustable spray volume so that the doctor fatigue. Noise: ≤ 65dB, cooling mode: air mist / water mist dual-channel, adjustable spray volume so that physicians just convenient operation, drive mode: pneumatic / electric
2.Application Scene and Needle Matching
Caries decalcification with ball drill / conical crack, remove decay, preparation of cavities, operation with short breaks to avoid heat generation.
Full crown preparation with diamond needle coarse/fine grain, for dental grinding and contouring, continuous water cooling during operation to keep the needle sharp.
Veneer preparation with ultra-fine-grained diamond needles (≤40μm) for minimally invasive enamel removal, if a magnifying glass is used to assist in the delicate operation to ensure precision.
High-speed dental handpieces are also used in a wide range of surgical and specialized applications, such as extractions and splitting of teeth, splitting of multiple teeth, and opening of implant guides.
3. Operation and use standardization
The mainstream drive mode of high-speed handpiece is pneumatic, connect the power source before use, check whether it reaches the working air pressure, access to 2.2~2.8 bar compressed air, check whether the pipeline is leaking, load the needle in accordance with the standardized steps, press the chuck→insert the needle→rotate to test whether it is firm (no shaking), because the instrument is high-speed operation, so in the use of the process must pay attention to the cooling, after starting to observe whether the spray evenly covers the turning plate opening. Observe whether the spray evenly covers the head of the needle after startup and adjust the ratio of water and gas when it is insufficient Prohibit operation without water, the use of standardization can make the treatment process safer!
