Optimu Rotary




Any practice looking for a simplified option for adjusting hard-ceramic crowns and bridges.


Whenever adjusting hard-ceramic restorations.


Delivering a superior price-performance ratio vs similar options, Optimu Rotary’s ZKD4 kit contains 5 Lion diamonds and 2 Lamello polishers that ease final adjustment of hard-ceramic restorations. Providing rapid, precise, cool cutting paired with durability and long-term performance, Lion diamonds were tested and ranked “best in class” by Clinicians Report (October 2012) for use on hard ceramics. The Lamello polishers feature an open-spiral construction that minimizes heat development, and they incorporate an exceptionally high concentration of interspersed diamonds that enhance instrument durability. The flexible, long-lasting polishers readily adapt to all restoration surfaces and can be used intuitively at any angle to achieve a brilliant, finished quality.

The How

For chairside adjustment of zirconia and other high-strength ceramic restorations, select the appropriate Lion diamond and use with a water-cooled, high-speed handpiece. For optimal results, apply light pressure until the desired result is achieved. Next, use an intuitive, 2-step technique with the diamond-impregnated blue (medium) and pink (fine) Lamello polishers. The wheels readily adapt to all surfaces and can be used from any angle to achieve a brilliant, high-shine finish.
