EZ Smile 3-Step Diamond Spiral Polishing Kit is a professional diamond-impregnated polishing system for finishing and polishing porcelain, ceramic, zirconia and lithium disilicate restorations. Its flexible 14 mm spiral wheels adapt to curved, contoured and occlusal surfaces while helping preserve the restoration’s anatomy.
The colour-coded three-step sequence progresses from smoothing to pre-polishing and final high-gloss polishing. The kit includes two polishers for each stage, for a total of six.
Three-Step Polishing Sequence
- Step 1 – Blue Coarse: Initial smoothing and reduction of minor surface irregularities after contouring.
- Step 2 – Pink Medium: Pre-polishing and intermediate refinement to prepare the surface for the final stage.
- Step 3 – White Fine: Final polishing for a smooth, high-gloss surface.
Suitable Restorative Materials
Designed for professional polishing of compatible:
- Porcelain and feldspathic ceramic
- Zirconia restorations
- Lithium disilicate and glass ceramic
- Veneers and laminates
- Crowns and bridges
- Inlays and onlays
Flexible Spiral Design
The open spiral geometry provides broad yet flexible contact with the restoration. The polishing elements adapt to occlusal, buccal, lingual, facial, incisal and interproximal surfaces, including grooves and curved contours. This design helps reach multiple surface shapes without frequently changing instrument geometry.
Key Features
- Three-step Coarse, Medium and Fine polishing system
- Diamond-impregnated flexible polishing material

- 2.35 mm CA/RA latch-type shank for compatible contra-angle handpieces
- Recommended working speed: 7,000–12,000 RPM
- Maximum speed: 20,000 RPM; do not exceed
- Light pressure recommended for controlled polishing
- Reusable after validated cleaning, disinfection, packaging and Type B steam sterilization
- Six-piece kit: two polishers per stage
Recommended Speed and Technique
For routine polishing, operate within the recommended 7,000–12,000 RPM range using light, controlled pressure. Keep the polisher moving across the surface and avoid prolonged contact in one area to limit unnecessary heat generation. The stated 20,000 RPM is the maximum permissible speed, not the preferred working speed.
Complete all three stages in order for progressive refinement. Clean the restoration between stages so particles from the previous grit do not interfere with the next polishing step.
Directions for Use
Use with water cooling throughout polishing. For intraoral use, provide a water spray of at least 50 mL/min.
Polish with light pressure and gentle circular movements, completing all stages in the specified order. Increasing speed does not necessarily produce faster results; excessive speed increases heat generation and instrument wear. Stay within the recommended working speed range and never exceed the stated maximum speed.
- Confirm compatibility with the restorative material and contra-angle handpiece.
- Inspect the wheel and shank before use. Do not use a damaged, distorted or excessively worn instrument.
- Secure the 2.35 mm CA/RA shank in a compatible low-speed contra-angle handpiece.
- Begin with the Blue Coarse polisher for initial smoothing.
- Continue with the Pink Medium polisher for pre-polishing.
- Finish with the White Fine polisher to achieve the final gloss.
- Use light pressure, keep the instrument moving and remain within 7,000–12,000 RPM.
- Stop once the desired surface finish is achieved. Never exceed 20,000 RPM.

Cleaning and Reprocessing
After cleaning and disinfection, make sure the polishers are completely dry. Package them in a suitable sterile barrier system intended for steam sterilization and double-pack them according to DIN EN ISO 11607. Steam sterilize using a fractionated pre-vacuum Type B process at 134°C with a minimum holding time of 3 minutes (minimum 5 minutes in Germany), or at 132°C with a minimum holding time of 3 minutes as a validated parameter. Longer holding times are permitted. These are holding times at the sterilization temperature, not the total machine-cycle time. Allow the packaged instruments to cool after the cycle and inspect the packaging for damage. A maximum of 10 reprocessing cycles is permitted; discard an instrument earlier if it is damaged, distorted, excessively worn, loose or no longer rotates concentrically.

We’ve been using this polishing kit from EZ Smile for over two years and it’s still our favourite. The diamond impregnated rubber wheels give a smooth finish every time. Super reliable and easy to sterilize. Great value and fast delivery in Canada.
