Ep. 651 - The Comeback of Air-Driven Handpieces

Should you make the leap to electric handpieces, or could the latest air-driven technology deliver the power you need while maintaining the ergonomic advantages you prefer?

Dr. Miles R. Cone brings a unique perspective to this handpiece debate. A graduate of Tufts University School of Dental Medicine, he completed a three-year prosthodontic residency while serving as a Major in the United States Army. As one of only two prosthodontists in New England with additional qualifications as a Certified Dental Technician, Dr. Cone combines clinical expertise with technical precision. He owns Nuance Dental Specialists in Maine and serves as Editor in Chief for the Messenger, the American College of Prosthodontists' quarterly publication.

This conversation explores the evolution of handpiece technology and challenges conventional wisdom about electric versus air-driven systems. Dr. Cone shares his journey from exclusively air-driven to electric during the pandemic, then back to advanced air-driven handpieces that rival electric performance. The discussion covers real-world clinical scenarios, from removing multiple zirconia crowns to creating precise margin preparation, offering practical insights for prosthodontic and restorative workflows.

Episode Highlights:

• Advanced air-driven handpieces now generate 44 watts of power, enabling rapid removal of full-coverage zirconia crowns in minutes rather than the extended timeframes previously required. The quick-stop functionality provides immediate cessation when the rheostat is released, enhancing patient safety during crown removal procedures.
• Hybrid handpiece systems allow prosthodontists to leverage air-driven units for bulk tooth structure removal and tight access areas, while switching to electric handpieces for refined margin preparation and final finishing work. This approach optimizes both efficiency and precision in comprehensive restorative cases.
• The 100-degree angled head design on newer air-driven handpieces significantly improves visibility and access in posterior regions, particularly beneficial for second molar preparations where space constraints and patient anatomy create challenging working conditions.
• Equipment longevity and reliability prove critical for practice productivity, with some micromotor units maintaining consistent performance after 11-12 years of daily laboratory use. Customer service responsiveness and repair turnaround times become essential factors when selecting handpiece manufacturers for practice investment.
• Cost considerations favor upgrading to advanced air-driven handpieces over complete operatory retrofitting to electric systems, particularly for new associates or practice transitions. The performance gap between high-end air-driven and electric handpieces has narrowed substantially, making air-driven a viable alternative without infrastructure changes.

Perfect for: Prosthodontists, restorative dentists, and general practitioners evaluating handpiece technology upgrades, particularly those working with zirconia restorations and complex crown removal procedures.
