Although pneumatic dental handpieces have been improved, their electronic handpieces have improved efficiency and accuracy.
In the past decade, many new technologies have been incorporated into dental practice, including digital impression systems, diode lasers, digital radiography, LED curing lights, and caries detection equipment, but many individuals are using exactly the same dental handpiece.
This is likely to be a pneumatic handpiece with a high whistle and a moderate amount of torque.
The whistle and vibration of these dental handpieces often cause considerable anxiety for our patients, and the soothing environment that clinicians try to provide in their offices can be destroyed when they step on a varistor.
The question must be asked whether the handpiece has exceeded these issues.
Boden high-speed pneumatic dental handpieces were first introduced in 1957, and this introduction has completely changed the dentistry; however, from now on, only incremental changes have occurred on the air mobile stage. Today's pneumatic dental handpieces are certainly lighter, smaller, and quieter than ever; however, these advances are still relatively small. Practitioners continue to argue about the fact that air-powered dental handpieces often lose their cutting efficiency due to dense materials, and patients continue to have anxiety due to the noise and vibration of these handpieces.
The solutions to these problems are related to the electric handles. Electric dental handpieces have been on the market for many years, and Europeans and Asians will not consider returning to the air to drive dental handpieces, but the penetration rate in the United States remains low. U.S. practitioners have been slow to adopt this technology because traditional electric handpieces are often bulky, bulky, difficult to maintain, and somewhat messy to use.
The market is clearly aware of the fact that electric handhelds have a large torque that results in cutting efficiency; however, in many people's eyes, the sheer size of the product and the warnings associated with potentially burning patients are not worth it.
In a pneumatic handset, speed is a function of the amount of compressed air that can flow through the turbine. Unfortunately, when the rotary cutting apparatus encounters resistance, its rotational speed decreases and the cutting efficiency is lost. In addition, air handsets tend to have considerable vibration and the concentricity of rotating instruments is reduced.
In an electric dental handpiece, air acts as a speed regulator only when the air is close to the sensor. When the wire rope encounters resistance, the motor can output more energy and continue cutting at substantially the same speed.
Historically large motors with complex carbon brushes have been required to maintain this level of torque. Equally important is that electric dental handpieces can be cut more concentrically, resulting in highly refined preparations.
Compared with previous generations, the advancement of electric dental handpieces allows us to be lighter, smaller, quieter, easier to maintain and easier to operate. In addition, these advantages will not sacrifice the huge torque and precision cutting ability of the electric dental handpiece.
Weight and size
In the past few years, the size and weight of electric dental handpieces have fallen dramatically. Manufacturers such as KaVo, Bien Air, SciCan and NSK now offer short motors that are 30% to 40% lighter than motors a few years ago and shorter than short motors. In addition, companies like Kavo and NSK now have ultra-small head designs, so electric handpieces can be used for people with smaller openings.
be quiet
The noise level of traditional air-powered dental handpieces has always been a nuisance to the patient and may impair the clinician’s hearing during his career. Today's manufacturers have nearly 20 decibels of power handles lower than traditional air mobiles. It is estimated that the human ear feels a reduction of 10 decibels, and the loudness is reduced by almost 50%.
maintain
In the past few years, the electric handsets contained carbon brushes that needed to be replaced regularly to maintain the desired performance. Today's handpieces are brushless, and many manufacturers have created simple plug-in cleaning units to help maintain the handpiece's precise performance.

easy to use
In the past few years, many people believe that the use of electric handsets is confusing because all adjustments can be made. Manufacturers now integrate simplicity into handheld devices by integrating easy-to-use touch panels and pre-programmed functions. Manufacturers like Bien-Air have integrated the iPad into its surgical head product line, and KaVo has developed a product called COMFORTdrive, a simple plug-and-play electric handpiece that does not require any adjustments. .
Professionals can use the new generation of electric handsets, and practitioners should consider upgrading these high-precision instruments. For added comfort, this upgrade will immediately draw the patient’s attention. In addition, this will bring positive return on investment in terms of practical efficiency and accuracy.
