NSK has released the Ti-Max Z99L, a new electric handpiece attachment developed to meet evolving clinical demands, particularly in procedures involving zirconia and other high-strength materials. According to the company, the Z99L builds on the performance of its predecessor, the Ti-Max Z95L, with a redesigned chuck mechanism, optimized internal gearing, and refined bearing configuration aimed at enhancing both durability and cutting efficiency.
The new handpiece features a 100-degree angled head with slim dimensions to improve intraoral access and visibility. According to NSK, the bearing and gear updates not only increase mechanical longevity but also help reduce noise and vibration during operation. The unit’s solid titanium body is approximately 30% lighter than stainless steel and is coated with a scratch-resistant surface designed to improve grip and reduce hand fatigue.
A key feature of the Z99L is its Two-Way Water Function, which allows clinicians to switch between mist and jet irrigation depending on procedural requirements. Jet mode, used without chip air, is designed to reduce the risk of subcutaneous emphysema during invasive treatments. Mist mode offers enhanced cooling of the bur and tooth surface to help prevent thermal damage.
The product also incorporates NSK's Quattro Spray system, which uses four water ports positioned to maintain effective cooling regardless of bur shape or intraoral conditions. Heat reduction has also been addressed through the handpiece's head-cap design and internal load distribution, helping minimize the risk of overheating during high-speed use.
Contamination control is supported by NSK’s DualDefense System, which includes an anti-retraction valve and a mechanism designed to keep contaminants from entering the head.
The Ti-Max Z99L is covered under a three-year warranty, according to the company.
