Rocky is a short flat end cylinder used for slitting ceramics like zirconia and lithium disilicate.
Superior clinical experience. Rocky is 74% sharper* than competing crown cutters, lowering your hand fatigue, reducing the risk of microfractures, and giving you better tactile control.
See more patients. Rocky helps you increase your profit without working longer hours because it’s 87% faster* than competing crown cutters.
No more burning through burs. Rocky was engineered to last longer than your average crown cutter. It powers through multiple crown removals without dulling, minimizing mid-procedure swaps, reducing overhead, and keeping your day running smoothly.
Have a clear posterior view. Rocky is available in short round-end and flat-end cylinders to give you an unobstructed view when slitting posterior crowns.
Stay organized. Rocky’s rose-gold shank makes it stand out from other burs, helping you easily identify the right instrument when you’re on a tight schedule.
Rocky is also available in the following shapes:
Long, tapered chamfer (CERC)
Short flat end cylinder (CERCS.FG.016)
Directions for Use:
In front teeth, cut across the axial surface up to and beyond the incisal edge. For molars, cut along the occlusal surface to simply break the crown open
Adhesive crowns can be opened piece by piece with crown dilating forceps. Start in the cervical region – as far as you can – and then remove further fragments step by step, working in an incisal or occlusal direction.
Grind down any remaining fragments with the long-tapered chamfer shaped Rocky.
Technical Details:
Optimal speed: 160,000 rpm
Always work with sufficient cooling (at least 50 ml/min)
Do not exceed a maximum contact pressure of 2N
We recommend reducing the speed to 120,000 rpm when working on alloys that make instruments “skip”. Alternatively, you can work with a dental turbine at low contact pressure.
For an optimum cutting performance, apply the instrument to the crown/ filling at an angle of 45°
