Let DYM crown handpiece shares with you the structure and usage suggestions of handpiece

There are many types of dental handpieces, which can be categorized as high-speed or low-speed based on their speed and structure. High-speed handpieces utilize high-pressure air to drive a micro-turbine within the handpiece head, achieving speeds of 280,000 to 500,000 rpm. The cutting speed of the bur can reach 15 m/s, while high-speed handpieces rotate at approximately 280,000 to 450,000 rpm.

High-speed dental handpieces primarily perform tooth cutting, grinding, restoration, and polishing.

Faced with the wide variety of dental handpieces on the market, clinicians should consider price, lifespan, maintenance costs, and brand reputation when choosing and purchasing, avoiding blindly pursuing the lowest price. Foshan Duoyimei’s high-speed dental handpieces boast speeds of 300,000 to 500,000 rpm, a stable, concentric shaft, smooth operation, excellent durability, and low noise at high speeds, ensuring comfort for both dentists and patients. During dental procedures, dental handpieces come into close contact with patients’ saliva, blood, gingival crevicular fluid, and dental plaque. The surface of dental handpieces, as well as the turbine components and tubing within the handpiece, can become contaminated with pathogens to varying degrees after use. Dental procedures often result in injuries to mucous membranes and skin, and many blood-borne and infectious diseases are transmitted through wounds caused by improperly sterilized dental handpieces. Dental handpieces are precision-engineered and complex. The turbine chamber, water and air channels, and other accessories within the handpiece contain complex cavities and difficult-to-access tubing. These specialized structures are susceptible to contamination and difficult to thoroughly disinfect during backdrafts caused by handpiece downtime. Due to the cumbersome disinfection procedures, high costs, and the risk of damage during disinfection, the high price of traditional handpieces, and the large number of dental patients, it is difficult for general dental institutions to meet the national standard of “one person, one use, one disinfection or sterilization.” The anti-backdraft design of the Duoyimei quick-connect high-speed handpiece reduces cross-infection between dentists and patients. This uniquely designed impeller ensures a powerful cutting force. The handpiece’s duct is equipped with a water filter and anti-backflow device, effectively filtering impurities from the handpiece’s pipes and preventing backflow of used water, making it user-friendly for both dentists and dental patients.

To ensure a long and durable dental handpiece, the following points can extend its lifespan by approximately two-thirds. The lifespan of a handpiece depends primarily on proper cleaning and maintenance:

1. It is recommended that the air compressor be cleaned, filtered, and drained regularly, as the compressor cylinder contains a large amount of iron filings, sewage, and dirt. The correct way to use a high-speed dental handpiece is to remove impurities and moisture from the compressor to extend the bearing life.
2. Avoid using inferior burs. Ensure that the burs you use match the handpiece chuck. Inferior burs can damage the chuck. Dental handpieces are extremely delicate. International standard burs for proper use generally have an outer diameter of 1.60mm to 1.59mm. A diameter that is too small will make the bur difficult to grip. Avoid worn, damaged, bent, or rusted burs. Burs with diameters too large will not fit in the handpiece. DYM diamond burs are excellent. They are made of stainless steel, standard specifications, and are made from South African diamond abrasives with a special electroplating process. The head contains ample grit and comes in red, yellow, green, and blue grit for different functions. Each bur can grind 3 to 6 teeth, meeting the daily needs of different dental clinics. We also welcome agents of international dental burs to test and select from them. Check the water and air pressure before use. Ensure that they are within the equipment’s specified range. Excessive air pressure can affect bearing life. The operating water pressure is generally 2 kg, and the operating air pressure is generally 0.25-0.28 MPa.
3. Clean and lubricate to remove residue. Consider the bearing material and manufacturing process, internal piping materials, and handpiece production. Bearings are precision components of turbine handpieces. Clinicians know that they are fragile and can easily damage the handpiece if not properly cleaned and maintained. Traditional handpiece bearings are mostly made of steel, and the movement typically consists of an outer ring, inner ring, retainer, and balls. Ceramic ball bearings are now commonly used. Dental high-speed handpiece maintenance primarily includes pre-use inspection, post-use cleaning, regular lubrication, and proper sterilization. Maintenance aims to remove residual debris, reduce wear, and extend handpiece life. Use a handpiece-specific cleaning agent to remove dental debris and residue inside the handpiece to prevent it from affecting the speed. During cleaning, avoid contact between the cleaning agent and the handpiece tubing to prevent hardening. Select a lubricant specifically designed for handpieces to lubricate the high-speed bearings. DYM SKI high- and low-speed handpiece oil uses food-grade oil with a fresh scent and excellent bearing lubrication. If your dental clinic uses a large number of dental handpieces, we recommend using a handpiece cleaning and oiling machine. This ensures more thorough oiling, cleaning both the pipes and bearings. Then, oil is added and air-dried, ensuring smoother handpiece operation. For well-maintained handpieces, after cleaning and disinfecting them, apply 2-3 drops of lubricant (15 ml) to the bearings. This pure oil, without any additives, ensures optimal lubrication and prevents sticking. Well-maintained dental handpieces are efficient and quiet.
4. Sterilization
   Perform standard sterilization: According to relevant specifications, sterilize with pre-vacuum pressure steam at high temperatures, reaching 121°C for 20 minutes or 132°C for 15 minutes. Note: Drying should be performed after sterilization to prevent rusting. Do not immerse handpieces in water for disinfection.
5. Other daily precautions: Protect handpieces from drops and accidental impacts. When not in use, place an empty needle inside the handpiece to protect the inner core. Dropping or impacting a dental handpiece can significantly impact its effectiveness.
