W&H handpieces from Critical Dental are trusted and sophisticated pieces of dental equipment. A W&H handpiece helps a dentist perform even delicate tasks with reliability and precision. This raises several questions. What’s the technology behind a W&H handpiece? What are the different kinds of W&H handpieces? What are some W&H handpiece maintenance guidelines? 


W&H handpiece technology 

W&H surgical handpieces are sophisticated in several ways and designed with ease of use in mind. Both the straight and contra-angle W&H handpiece models can be attached to air motors or electrical motors, providing you, the dental practitioner, with a range of options for your practice. 

Additionally, all of their handpiece models—other than the W&H WI 75 E KM implant handpiece—are made out of stainless steel and are coated with a scratch-resistant protectant. This makes them exceptionally long-lasting and durable. Their ergonomic design helps to reduce hand fatigue during longer procedures, thus rendering each procedure safer for the patient and more enjoyable for the practitioner. 

The straight W&H handpieces are specifically designed for precision in implantology, maxillofacial surgery, and oral surgery. 


W&H handpiece models 

Critical Dental offers virtually every model of W&H handpiece. Below are some examples.

W&H handpiece maintenance 

To maintain your W&H handpiece for maximum performance and longevity, it’s important to keep up with regular product servicing.

There are two main types of device maintenance: in-practice cleaning and out-of-practice repair.

If you’re unsure of an issue concerning your W&H handpiece, it may be the time to send your device in for professional maintenance.

While Critical Dental makes a point to supply only the best handpieces, even the most reliable of equipment takes a beating from daily use.

  4. Inspect your handpiece
    • The device should look clean
    • If not, repeat steps 2-3
