What Aspects of Dental Handpieces as Core Tools for Oral Diagnosis and Treatment are Worth Paying Attention to?

Dental handpieces are essential tools for dentists performing procedures such as tooth preparation, caries restoration, and periodontal therapy. Their performance directly impacts diagnostic and treatment efficiency and outcomes. Dental handpieces are precision medical devices that require strict disinfection and sterilization protocols to prevent cross-infection. Studies have shown that the probability of detecting HBV in the turbine chamber of unsterilized dental handpieces is as high as 32%. DYM Dental Equipment Factory will share insights from four perspectives: classification, technological innovation, maintenance, and future trends.

I. Definition and Classification of the Dental Handpiece

Basic Definition
Dental handpieces are handheld instruments that transmit energy to dental tools. They are categorized into two types based on speed and structure:
High Speed Handpieces: These rotate at speeds of 300,000-450,000 rpm and are used for grinding and cutting tooth tissue. They consist of the handpiece head, body, and connector. They are categorized by burs Dental Burs Supplier removal method: key type and push button. They are also available with or without a light, and with or without a quick connector. They are used for daily dental polishing and cavity restoration. High speed dental handpiece
Low Speed Handpieces: These rotate at speeds of 20,000-30,000 rpm and perform functions such as drilling and polishing. These include models with air and electric motors. They are used for cleaning and polishing after fillings. SKI low speed handpiece

Structural Features of Dental Handpieces
High speed handpieces generally consist of a dental handle (body), handpiece head, impeller, push-type shaft, bearings (including steel ball bearings and ceramic bearings), handpiece back cover, sealing gasket, and air and water pipes.
Low speed handpiece sets are typically composed of a motor, straight or contra-angle handpiece.

DYM is a source manufacturer specializing in the production of dental equipment. Its high and low speed handpiece sets use imported ceramic bearings. All dental handpieces have passed the German dynamic balancing equipment test and run silently to meet the needs of different dentists for drilling, grinding, restoring and polishing. They are suitable for major dental hospitals, dental clinics, dental schools, etc.

Ⅱ. Technological Innovation and Safety Improvements of the Dental Handpiece

Anti-Backdraw Bearing Technology
After stopping a conventional handpiece, the inertial rotation can cause foreign matter to be reabsorbed into the mouth, increasing the risk of infection. Therefore, a bearing technology is now available on the market that uses a sealing ring to instantly stop rotation, blocking the backdraw path and is also sterilizable at high temperatures. Important considerations: Bearing spacing ≥ 0.2mm, air flow ≤ 10L/min.

For example, DYM latest high speed handpiece, featuring a one-piece stainless steel handpiece head, is drop-resistant and effectively prevents backdraw. A unique filter screen filters out impurities in the water, preventing them from entering the bearings and damaging the handpiece. The four water outlets in the handpiece head provide rapid cooling, preventing discomfort to the patient caused by overheating of the handpiece and bur during high speed operation. The water filtration system in the handpiece pipe was specially designed by DYM engineers based on extensive user feedback from dentists. This effectively filters impurities, ensuring cleaner water entering the handpiece pipe, thereby extending the life of the dental handpiece.

Ⅲ. Key Maintenance Points for the Dental Handpiece

Cleaning and Sterilization Process
Necessity: Contact with patient body fluids can easily lead to the contamination of pathogenic microorganisms in the impeller chamber and tubing of dental handpieces. Therefore, “one person, one handpiece, one sterilization” is essential.
Standardized Process:
Ultrasonic cleaning → Oiling and lubrication → Packaging → High pressure steam sterilization.
Oiling Warning: Excessive oiling can prevent the sterilizing steam from penetrating the interior, resulting in “oil pocket” contamination.

DYM Dental Equipment’s original factory provides one-stop dental equipment sales, installation, and after-sales services. We can equip dental chairs with high and low speed handpieces, handpiece cleaning and oiling machines, handpiece lubricants, diamond burs, oral camera, wastewater treatment equipment, suction machines, and other dental equipment to meet the diverse needs of new dental clinics, dental institutions, and dental equipment distributors and agents.

Daily Maintenance and Recommendations for Dental Handpieces
Regular lubrication can reduce failure rates and extend service life.
Avoid collisions and drops, and ensure stable operating air pressure. Regularly clean impurities and pipes.

Regular lubrication of dental handpieces is essential, but choosing a good lubricant is also crucial. Don’t forget to do this after using a high speed handpiece daily. Be sure to clean impurities from the handpiece’s bearings and the water and air pipes. Otherwise, high speed operation can cause friction and damage. DYM high and low speed handpiece cleaning lubricant Dental Handpiece Lubricating Oil is food-grade, highly pure, fresh-smelling, and safe, free of impurities. After each use, spray the handpiece several times into the hole at the rear of the handpiece until the oil flows out of the handpiece head. Properly lubricated handpieces can extend their lifespan by approximately one-third compared to poorly maintained ones.

Ⅳ. Industry Challenges and Development Trends for Domestic Dental Handpieces

Existing Issues with Handpiece Use in Clinical Practice

Repeated high-temperature sterilization accelerates component wear and shortens device life. Some dental clinics and hospitals do not properly clean dental handpieces, leading to pathogen contamination on the handpiece surface. Some dental clinics and hospitals lack dedicated, professional personnel for cleaning and maintenance.

Future Innovation Directions for Dental Handpieces

Material and Dynamic Optimization: Disposable handpieces utilize a lightweight design and utilize dynamic modeling to improve operational precision. Intelligent Assistance: Smartphone applications (such as dental emergency guides and clinic management software) assist clinical decision-making, but must be integrated with traditional technologies. Sterilization Technology Upgrade: Research on low-temperature sterilization to reduce thermal damage. Precise speed and uniform output frequency of electric dental handpieces.

As a core tool in daily dental care, the safety, efficiency, and innovation of dental handpieces are directly related to the quality of dental medical technology. The dental handpieces currently developed and produced by DYM Medical all feature high-precision ceramic bearings, an integrated stainless steel handpiece, a double-layer impeller drive, and a built-in cleaning and impurity-filtering pipe design. These are highly compliant with current infection control and sterilization protocols in dental clinics and hospitals, ensuring efficient and convenient use by dentists.

In the future, the integration of disposable handpiece design, intelligent assistance, and materials science will further promote safer and more precise dental care. Healthcare professionals must strictly adhere to maintenance protocols to ensure that dental handpieces continue to play their core role in health protection. DYM Medical will closely monitor the development of future dental treatment technologies and independently develop more dental handpieces that are more suitable for dentists. Given the increasing demands of dental patients for infection control and the challenges dentists face in achieving efficient and comfortable work, it is imperative to develop a dental handpiece that is popular with dentists. Future dental handpieces should enable dentists to achieve more precise polishing, improve patient comfort, and deliver precise, uniform torque output with low amplitude, making dental care easier for patients and less intimidating for them, ultimately achieving a new standard of healthy teeth for everyone.
