Dental laboratory handpiece

Types of dental laboratory handpiece

One of the most critical instruments in any dental lab and clinic, a dental laboratory handpiece, makes the fabrication of crowns, dentures, bridges, and other dental repairs possible.

These handpieces vary in function and usage. The common types include:

• High-speed dental handpieces

  As their name suggests, these handpieces allow precise cutting and shaping of teeth. Dental practitioners prefer them for carrying out complicated procedures while minimizing damage to the tooth structure. They are an indispensable instrument in any modern dental facility requiring accuracy and efficiency.

• Low-speed dental handpieces

  These are less powerful than the high-speed models and are mainly used for polishing, carving, and other non-extraction-related tasks. Their slower but more controlled rotation makes them ideal for filling-related work or surface treatments. Any user wanting more control over low-impact dental applications would prefer this type of handpiece.

• Laboratory handpieces

  These handpieces are designed specifically for use in dental labs during crown, bridge, denture, and other restorations. Often more robust than their clinical counterparts, they handle dental materials like plaster and porcelain. Any dental facility with in-house restorations should prioritize buying sturdy laboratory handpieces.

• Electric handpieces

  Electric handpieces are powered by an electric motor rather than air pressure. This difference offers more torque and consistency in operation. Electric handpieces are increasingly popular, especially when performing tasks requiring high precision.

• Cordless handpieces

  These are battery-operated handpieces that provide freedom of movement. They are convenient for quick procedures and offer portability. Cordless handpieces are best for dental professionals who need an efficient tool for minor adjustments or quick procedures on the go.

Durability and material of dental laboratory handpiece

• Stainless steel

  This steel is famous for making handpieces. It is a strong, non-corrosive, and highly resilient material that can withstand prolonged use. Stainless steel handpieces can endure wear from high-speed operations without compromising their structural integrity. In addition, they are easier to disinfect, making them suitable for the demands of clinical and laboratory environments.

• Aluminum alloy

  Aluminum alloy handpieces are lighter yet still durable, enhancing maneuverability. This weight reduction proves helpful during extended procedures, reducing practitioner fatigue. While often more affordable, aluminum alloy handpieces maintain good durability, though they may require more frequent checks for wear.

• Ceramic materials

  Ceramic handpieces are a-rated for their durability. Being non-corrosive, ceramic handpieces retain aesthetics even after prolonged use. Their hard surface makes them resistant to wear. Because these materials are often more brittle than metals, they are less likely to break in case of accident. They are ideally suited for practitioners prioritizing a striking aesthetic and high-performance equipment.

• Composites and plastics

  While these are often not as durable as metals, advances in technology have enhanced the wear resistance of these materials. These lightweight materials are often used for more affordable models or specialty applications. It is important to note that they will not have the longevity of steel or ceramic and may require more frequent replacements. These materials are often included in cordless models for their lightweight and more affordable nature.

How to choose a dental laboratory handpiece

• Choose based on durability

  The handpiece is an important investment any clinic makes and should ideally last several years. Choose a handpiece made from durable materials like stainless steel or ceramics that can withstand frequent use without significant wear. Consider the level of maintenance as well; low-maintenance models could save time and costs in the long run.

• Select based on comfort and ergonomics

  Comfort is also vital, especially for dental professionals carrying out lengthy procedures. One must select an ergonomic design that fits snugly within the hand to minimize fatigue as one works for long hours. Pay attention to the weight and grip of the handpiece; a good fit could substantially reduce strain on the hand and wrist.

• Make sure there is compatibility with existing equipment

  Certainly, one should check that the new handpiece is compatible with existing dental equipment, such as turbines and couplings. There are some handpieces specifically designed to be electric that may not be compatible with pneumatic systems. One should make sure the new purchase works with other dental tools to avoid extra costs.

• Look for precision and control

  In dentistry, precision is highly needed, especially when carrying out restorations or other intricate procedures. One should select a handpiece that comes with adjustable speed settings and a sturdy grip to ensure better control during operations. Precision and control are indispensable to obtain quality results and patient satisfaction.

• Do not forget asking the warranty

  Handpieces vary considerably in their quality and reliability, which sometimes depend on the manufacturer. One should ask for the warranty period as an indicator of the manufacturer's faith in the product's durability. More extended warranties usually mean that the instrument will last longer and that the company stands behind its performance. There should be no hesitance in asking these essential details because they are required to make an informed decision.

Scenarios where a dental laboratory handpiece is used

• Dental restorations

  Dental lab handpieces are key equipment in making crowns, bridges, and dentures. In labs, dental technicians employ high-speed and low-speed handpieces to precisely cut and shape materials like porcelain and acrylic. Dental handpieces are vital for delivering quality restorative work, whether done on-site in a clinic or outsourced to a dental laboratory.

• Dental impressionDtaking

  In the process of impression-taking, accuracy is crucial for giving the right shape and position of teeth for the making of dentures, bridges, or other restorations. Practitioners use low-speed handpieces during this process to smoothly prepare the teeth, reducing discomfort and ensuring that they're taking the best possible impression. The quality of the tools impacts the results; great dental impressions lead to an accurate restoration.

• Orthodontic applications

  Dental laboratory handpieces find their way into orthodontics in wire bending and other procedures. Technicians working on orthodontic appliances like braces and retainers use handpieces to shape and adjust materials. Precision is so critical in orthodontics that even small mistakes can lead to ineffective treatments. For this reason, powerful yet precise handpieces are endorsed for orthodontic work.

• Dental repairs and modifications

  Dental handpieces are used in the laboratory to perform repairs or modifications for crowns, bridges, dentures, or other existing dental work. Technicians use both high-speed and low-speed handpieces to redefine, repair, or refurbish prosthetics, ensuring that restorations attain the desired precision and fit. Handpieces with a variety of burrs and attachments provide unmatched versatility in repair tasks.

• Materials testing and Finishing

  Dental technicians use laboratory handpieces during the testing of dental materials to guarantee that they satisfy the industry specifications. They also utilize these handpieces to achieve smooth and polished surfaces on restorations, enhancing their strength and appearance. For this polishing and material evaluation, high-quality dental materials and reliable handpieces are critical for effective performance and longevity.
