NSK Dental LLC’s Ti-Max Z45L is a 45-degree electric (contra-angle) dental handpiece that provides effortless access to hard-to-reach molars that a standard contra-angle simply cannot match. The slim design of the Ti-Max Z45L also offers excellent visibility and high operability, creating more space between the hand-piece’s body and front and adjacent teeth. In addition, the Ti-Max Z45L’s powerful and consistent cutting shortens treatment time for sectioning and third-molar extractions, dramatically reducing stress for both clinicians and patients. The Ti-Max Z45L offers the world’s first two-way spray function: the water jet spray option prevents subcutaneous emphysema, while the mist spray option effectively cools the bur while cutting. This unique dual feature making the Ti-Max Z45L suitable for a wide range of procedures such as third-molar preparation and clarifications of the root canal orifice. The spray mode is changed via a small switch on the base of the handpiece using a small flat-head screwdriver tool that is included. The Ti-Max Z45L is versatile, handling burs ranging in length from 20 mm to 25 mm. Its ceramic bearings are 25% harder than conventional steel bearings but only half the weight; this significantly reduces the frictional wear between the ball bearings and the bearing retainer, thereby increasing both efficiency and durability. The handpiece’s body is made of titanium, which is 30% lighter than stainless steel, more durable and corrosion resistant. The resulting reduced weight and well-balanced shape give the Ti-Max Z45L a natural tactile sense and exceptional usability.
