Crown-Prepping Carbides

Designed in conjunction with Dr. Donald J. Alexander, the Crown-Prepping Carbides allow precise and controlled tooth reduction while providing a finished surface comparable to that achieved by a diamond finisher. The innovative design offers one of the quickest and smoothest chatter-free cutting patterns available.

The Crown- Prepping Carbides are engineered to match up precisely with the required chamfer or shoulder-prep design, depending on the desired material. They also facilitate for a fast and precise controlled tooth reduction and the resultant finish is so good, additional finishing instruments are not required.
