Table of Contents

Summary

Dental handpieces have evolved significantly from ancient bow drills to sophisticated, high-speed instruments powered by air turbines and electric motors

. These advancements have revolutionized dental procedures, making them faster, more precise, and more comfortable for patients. Bearings are critical components within dental handpieces, enabling the smooth and efficient rotation of dental burrs and other tools. These precision-engineered parts reduce friction, minimize vibration, and control heat generation, contributing to both the longevity of the handpiece and the comfort of the patient during dental procedures. The two primary types of bearings used are ceramic and steel. Ceramic bearings are favored for their superior performance, durability, and resistance to heat and corrosion, while steel bearings, though less resistant, provide reliable functionality in many dental applications. Despite their essential role, dental bearings are subject to wear and tear due to the high rotational velocities and demanding conditions under which they operate. Proper maintenance, including regular cleaning, lubrication, and adherence to manufacturer guidelines, is crucial to extending the lifespan of these components and ensuring consistent performance. Innovations in bearing technology and materials, such as advanced ceramics initially developed for aerospace applications, continue to enhance the durability and efficiency of dental handpieces. The field of dental handpieces is continually evolving, with future trends pointing towards further technological advancements, sustainability, and customized solutions tailored to the specific needs of dental professionals

Title: Benefits of hybrid ceramic bearings in dental instruments Url: https://dentalasia.net/benefits-of-hybrid-ceramic-bearings-in-dental-instruments/ Highlights: Radial bearings are beneficial because of their ability to be axially loaded from either side, while angular bearings can only be axially loaded from one side although with greater loads than the radial type. Although both bearing types are suitable for dental instrument applications, bearings with an angular contact configuration work best because of their ability to bear ‘combined loads’ in both radial and axial directions. Ceramic balls When deciding on which bearings are best for dentistry tools, using hybrid bearings with silicon nitride balls may be the best option. An advantage of hybrid bearings is that their ceramic balls are typically harder than heat-treated steel balls, making them less prone to causing external damage or bearing failure due to debris from surface wear.Bearings used in dental applications are available in a variety of forms and materials, leading to a discrepancy in quality and varying price points. Dental bearings are usually designed with precision, accuracy, and reliability in mind. In essence, there are two types of miniature bearings used for dentistry equipment: radial contact and angular contact bearings. These bearings are used differently, dependant on their purpose. The difference between these two types of bearings lies within the retainer type — radial bearings use what are called crown retainers, whereas angular bearings use full retainers.

Title: Rethinking the Dental Handpiece | Nov/Dec 2010 | Compendium Url: https://www.aegisdentalnetwork.com/cced/2010/12/rethinking-the-dental-handpiece Highlights: A technology has been introduced that many in the profession believe is a breakthrough. Called Speed-Sensing Intelligence, it actually monitors the bur speed several hundred times per second. A sensor in the coupler detects the frequency of vibrations from the rotating bur. When the bur encounters a higher load that would normally decrease speed, a signal from a small chip in the control source increases air pressure to maintain speed, virtually eliminating stalling to provide a smooth, consistent cutting speed regardless of load. This design provides exceptionally fast removal of tooth structure, amalgam, porcelain, and metal. Because the system adjusts speed when the bur is not under load, wear on bearings is minimized, which means fewer turbine replacements.Often, head sizes have been reduced to provide better visibility and access. Fiber-optic lighting was first integrated into handpieces in the 1970s and has dramatically improved the dentist’s ability to see the work area. Turbine cartridges have been steadily improved to enhance longevity and reduce noise. New bearing configurations and materials have been developed. Innovative materials have made it possible to repeatedly sterilize the handpiece without degradation in looks or performance. Chucking mechanisms have been improved with pushbutton releases to facilitate insertion and removal of the rotary instrument. Ergonomic improvements have made handpieces more comfortable and less tiring for the dentistHandpieces have evolved with the practice of dentistry and dental technology. High-speed electric handpieces now have a speed of 200,000 revolutions per minute (rpm), while high-speed air-driven devices function at up to 400,000 rpm and usually operate within 180,000 rpm to 330,000 rpm.Another technology, Superior Turbine Suspension, allows the handpiece to operate at 330,000 rpm under load, with no noticeable bur deflection or chattering. This provides control and a consistent transference of power from the handpiece to the bur, helping overall cutting efficiency. It is especially beneficial for margin refinements, veneer preparations, and other fine restorative procedures. One manufacturer is featuring new “Plug-n-Prep” auto-calibration technology. Because it does not require adjustment to other equipment, this system offers a simplified setup and a seamless transition. Once calibrated, this system allows for an air-like “feathering” effect between 30,000 rpm to 200,000 rpm with the foot pedal.Rethinking the Dental Handpiece David Little, DDS Thanks to significant advances in design and manufacturing, dentists today can—and should—expect more from their high-speed handpieces. Recent technologic breakthroughs have improved the cutting experience, making it faster and easier for the dentist and more comfortable for the patient. Where We Started and How Far We Have Come Handpieces are among the most commonly used mechanical devices in dentistry. No longer the primitive cutting tools introduced in the 1800s, handpieces are now highly efficient and sophisticated after a slow evolutionary process with incremental changes. Traditional handpieces are either air-driven or electrically driven.Until just a few years ago, handpiece technology had changed little. Recently, major advances in technology and manufacturing have challenged dental professionals to revisit their choice of handpieces. This will not only help make our work more precise but will also improve the patient experience. Exploring options and thinking outside the box when it comes to handpiece selection is crucial in this day and age. Although major progress with high-speed devices has been made recently, we still have challenges. Undoubtedly, more changes are coming, and we can look forward to the developments in this area.

Title: Failure Diagnosis for Dental Air Turbine Handpiece with Payload Using … Url: https://www.mdpi.com/2306-5354/11/6/555 Highlights: 3]. An experimental custom-made device was used to hold the high-speed handpiece and specimen in their cutting test. In their in vitro study, the user’s loading configuration was set to apply a load using the handpiece within the patient’s oral cavity. The handpiece and the specimen were fixed during the test. Therefore, this loading to the DATH was mimicked in this study. Zakeri and Arzanpour [ 4] utilized an accelerometer and a laser Doppler vibrometer to capture vibration signals while operating a dental handpiece. Through the comparison of spectrograms between the handpiece operating without load (free running) and under load (milling teeth), the aforementioned authors discerned a decrease in vibration frequency during milling. As the diagnostic perspective point of view, the vibration information from the free running after the milling process will be applied in this study after milling the specimen with a load of 0.9 N. Wei, Dyson and Darvell [ 5,1. IntroductionDental air turbine handpieces stand as the most prevalent medical apparatus employed by dentists in the treatment of teeth. The primary mechanical operation of the aforementioned equipment entails the infusion of high-pressure air into the head to activate microturbine blades, which in turn drive the rotation of bearings that power a tooth drill. Prior to or during treatment, dentists are unable to discern the state of health (SOH) or detect any damage within the internal components of a dental handpiece. Due to the high rotational velocity of a dental handpiece, its internal bearings progressively deteriorate and incur damage over prolonged usage. As a result, ceramic balls are unable to maintain stable operation along their confined track, leading to heightened internal friction within the machine head’s housing and an increase in temperature. The heat is transferred to the bur via the rotor, thereby elevating the temperature of the bur

. Dental bearings come in two primary types: ceramic and steel. Ceramic bearings are known for their superior performance and durability. They offer high resistance to heat and corrosion, reduce friction, and extend the life of the bearing. Additionally, ceramic bearings exhibit excellent vibration-damping properties, resulting in smoother operation and reduced noise levels. On the other hand, steel bearings, while not as resistant to heat and corrosion as their ceramic counterparts, still provide reliable performance and are commonly used in many dental applications. The composition and construction of dental bearings significantly impact their functionality. These bearings typically consist of an outer and inner ring, a cage to keep the rolling elements in place, and the rolling elements themselves. The precision and quality of these components directly affect the overall performance and longevity of the bearing. Bearings can also be classified into radial and angular contact types, each with specific benefits depending on their intended use. Radial bearings allow axial loading from either side, while angular contact bearings can only be axially loaded from one side but with greater load capacity.

Factors Influencing Performance and Lifespan of Bearings

Several critical factors influence the performance and lifespan of dental bearings, which are essential components in dental handpieces.

Maintenance Practices

Proper maintenance is crucial for extending the lifespan of dental bearings. This includes regular cleaning, lubrication for lubricated bearings, and timely replacement when signs of wear are evident

. Following a diligent maintenance routine helps avoid common issues such as wear and tear, contamination, and corrosion. Dental professionals should adhere to manufacturer guidelines for sterilization and usage to ensure longevity.

Title: Handpiece Maintenance and Repair – Henry Schein Url: https://www.henryschein.com/us-en/dental/events-education/article-Handpiece-Maintenance-and-Repair.aspx Highlights: . “In a world with so many technological advancements, the same things are happening with handpieces, extensive research and development and engineering are constantly occurring behind the scenes to bring dental offices the best quality, highest performing and longest lasting handpieces and equipment to the industry,” he says.Of course, even the best-maintained equipment will fail sometimes, so it’s important to know how to troubleshoot when you run into a problem and to distinguish between issues that can be solved in the office and those that require sending your equipment to a supplier for a fix. One common sign that something isn’t right is a change in the sound the handpiece makes when operating. This can range from a subtle shift in frequency to an unmistakable (and quite unpleasant) squeal. First, check if a damaged bur is the cause, in which case you may be able to replace it with a fresh bur and be just fine. If that doesn’t fix things, though, it’s probably time to call a repair service like Henry Schein Dental’s ProRepair and speak to a technician. They can help you diagnose the problem over the phone or let you know if you need to send the piece in for repairBeyond regular lubrication, it’s also important to make sure your sterilization processes aren’t leading to extra wear and tear on your handpieces. Commonly used cleaning products like wipes can damage equipment if not used correctly. Chemicals from cleaning wipes can seep into a handpiece’s seams and pores, saturating the O-rings and bearings within. When you then put the handpiece into a sterilizer, the high temperatures inside can essentially bake these chemicals into the handpiece’s internal components, causing premature degradation. To mitigate this problem, make sure the wipes you use aren’t overly saturated with cleaning fluid. This can be an issue especially when you’re getting toward the end of a container. Basic alcohol wipes are a better option for wiping off a handpiece prior to lubrication and sterilization. Because alcohol evaporates very quickly, it’s less likely to linger inside the instrument and cause damage. Also, less is more when it comes to wipes. “Since we began using this maintenance system, our repairs have decreased drastically,” he says. “For every 10 handpieces we used to send out for repair, we now send one. It has streamlined our maintenance procedures, and I recommend this unit to many of my friends and colleagues to use in their practices.” One tip for practices that opt for an automated maintenance system: pay attention to where you place it. Ideally you want it to be as easy as possible to move handpieces from the operatory to the maintenance system to the autoclave for sterilization.. Longacre says he recently dealt with an office that still had multiple handpieces in use after more than 25 years. “It’s a real testament to their maintenance protocols,” he says. For older handpieces, repairs aren’t always possible, given that many parts may no longer be available. New equipment, on the other hand, can almost always be repaired, but at a certain point the cost of those repairs might outweigh the price of just buying something new. And, as Mr. Longacre notes, there is always something new. He cited as one example the development of new single-use aerosol evacuators designed to reduce the aerosols produced by handpieces during procedures — an issue that has come to the fore during the COVID-19 pandemicThe good news is, manufacturers have developed automated handpiece maintenance systems that can process multiple handpieces at a time. Simply wipe your handpieces down after your procedures, put them in the maintenance system and it will lubricate the batch in about a minute, after which you can wipe down, sterilize and be ready to go. And because these systems are hands-free, you can take care of other bits of business while they work. Cameron Longacre, a technical services supervisor at Henry Schein Dental, explains that he has seen a decline in service calls from offices that have purchased the Maxima XTEND automated maintenance system. “They are getting much more use out of their handpieces, which really brings it to a much lower cost of ownership,” he says, adding that customers who purchase a maintenance system typically see a more than 20% decrease in repair costs. One recent customer, Dr. Jay Bauman, seconds that claim

. By investing in reliable handpieces and following proper maintenance protocols, dental professionals can ensure their tools perform consistently, allowing them to focus on delivering optimal oral health care to their patients.

Common Issues and Solutions

Dental handpieces are vital instruments in modern dentistry, and despite regular maintenance, issues can arise that require prompt troubleshooting and repair. Identifying and addressing these common issues is crucial to minimize downtime and ensure seamless operation.

Identifying Problems

One of the first indicators of a problem with a dental handpiece is a change in the sound it makes during operation. This can range from a subtle shift in frequency to an unmistakable squeal.

Title: Benefits of hybrid ceramic bearings in dental instruments Url: https://dentalasia.net/benefits-of-hybrid-ceramic-bearings-in-dental-instruments/ Highlights: Radial bearings are beneficial because of their ability to be axially loaded from either side, while angular bearings can only be axially loaded from one side although with greater loads than the radial type. Although both bearing types are suitable for dental instrument applications, bearings with an angular contact configuration work best because of their ability to bear ‘combined loads’ in both radial and axial directions. Ceramic balls When deciding on which bearings are best for dentistry tools, using hybrid bearings with silicon nitride balls may be the best option. An advantage of hybrid bearings is that their ceramic balls are typically harder than heat-treated steel balls, making them less prone to causing external damage or bearing failure due to debris from surface wear.Bearings used in dental applications are available in a variety of forms and materials, leading to a discrepancy in quality and varying price points. Dental bearings are usually designed with precision, accuracy, and reliability in mind. In essence, there are two types of miniature bearings used for dentistry equipment: radial contact and angular contact bearings. These bearings are used differently, dependant on their purpose. The difference between these two types of bearings lies within the retainer type — radial bearings use what are called crown retainers, whereas angular bearings use full retainers.

. If the noise persists, it might be time to consult a repair service, such as Henry Schein Dental’s ProRepair, for further diagnosis.

Troubleshooting Steps

To prevent and address common issues, consider the following steps:

  1. Check for Damaged Burs: If your handpiece emits unusual sounds, inspect the bur for damage and replace it if necessary.
  2. Regular Lubrication: Proper lubrication is essential to reduce friction between the ball and the inner and outer rings of the bearing, allowing the handpiece to rotate at high speed

    Reference [27]

    Title: Common problems handpiece, and maintenance methods – Dental In Box Url: https://www.dentalinbox.com/common-problems-handpiece-and-maintenance-methods/ Highlights: Cleaning is to prevent the foreign matter from entering the bearing and increase the friction between the ball and the inner and outer rings of the bearing. This is a process of replacing the water and foreign matter in the gas path of the handpieces with detergent and lubricating oil. Lubrication is to reduce the friction between the ball and the inner and outer rings of the bearing, so that the handpiece can rotate at high speed. We use professional handpieces lubricants for lubrication. Handpiece lubricants are liquid. When the handpiece bearings rotate at high speed, there will be a lot of loss and the bearings will be in a “dry” state. Therefore, we must strive to fill the handpiece before each use, so that the handpiece bearings are lubricated in time. status. According to different brands and models of handpieces , select the corresponding driving pressure.. Do not over-lubricate.. Therefore, in the usual use of the process should pay attention to the following three points:
    . Be cautious not to over-lubricate, as excess lubricant can cause issues during sterilization

    Reference [28]

    Title: The SMART way to lubricate dental handpieces – My NSK Url: https://mynsk.co.uk/articles/care-maintenance/the-smart-way-to-lubricate-dental-handpieces/ Highlights: Furthermore, the act of over-lubricating can lead to excess lubricant being discharged during the sterilisation process, causing damage to the autoclave, an issue common in older, single reservoir autoclaves which recycle dirty, contaminated water. Most importantly, if the inside of the handpiece is awash with lubricant, rather than the measured amount required to provide the optimum level of protection, steam penetration will be impaired resulting in a failure to effectively sterilise the handpiece. Automated systemsThe effective decontamination and sterilisation processes for precision-engineered handpieces remains a challenge, notably the cleaning of hidden internal surfaces and hollow channels (lumens). Concerns centre around the accumulation of debris and bodily fluids including blood and saliva, fragments of restorative materials as well as microorganisms from dental unit waterlines and airlines within the intricate working parts, gears, and turbine blades. The aim of the cleaning process is to ensure that surfaces are free of debris and matter, so that sterilisation can be effective. Any remaining debris will act as a barrier to steam penetration, especially if it’s baked onto surfaces as a result of previous exposure to the high temperatures associated with steam sterilisation. It’s important to remember that if something is not clean it cannot be sterilised. Look SMART
    .
  3. Proper Sterilization Techniques: Ensure that sterilization processes do not contribute to extra wear and tear. Chemicals from cleaning wipes can damage internal components if they seep into the seams and pores of the handpiece. Alcohol wipes are a safer alternative as they evaporate quickly. Additionally, remove the bur and release the chuck levers before sterilization to ease tension on the handpiece.

Maintenance Tips

  • Clean and Lubricate Regularly: Regular cleaning and lubrication are vital for maintaining the longevity and performance of dental handpieces. This prevents foreign matter from entering the bearing and increases friction between the ball and the inner and outer rings.
  • Monitor for Signs of Wear: Address any signs of wear immediately to prevent further damage. Investing in quality products from the onset can save costs in the long run.
  • Clean Turbine Chucks: Ensure that turbine chucks are cleaned weekly to prevent the bur from slipping or sticking, which could compromise patient care.
  • Handle Fiber Optic Surfaces Carefully: Use a cotton swab and alcohol to clean fiber optic surfaces, avoiding sharp instruments that could cause damage.

Seeking Professional Help

When troubleshooting steps and regular maintenance do not resolve the issues, seeking professional repair services is advisable. Experts can provide further diagnosis and necessary repairs to restore the functionality of the handpiece
