EXPERT OPINION Polishing zirconia after occlusal adjustment was always a concern until we found the Frank Dental zirconia polisher system. The three-grade sequence — coarse green, medium red, fine yellow — produces a consistently excellent result on monolithic zirconia and we have had outstanding results on lithium disilicate and feldspathic porcelain too. The key that catches people out: all zirconia polishing and cutting burs in this kit need to run at significantly lower speeds than a standard diamond, with high-volume coolant. If you are used to reaching for a coarse diamond on zirconia, the counterintuitive truth is that fine grit at controlled speed is actually more efficient — coarse burs burn and lose cutting ability almost immediately on zirconia. The Bur Stand Designed & manufactured by Incidental — 30 holes, fully autoclavable Holds the full kit with spare slots for your own additions. The open-hole design means you can autoclave burs seated in the stand with no decanting required. Numbered positions make reordering straightforward — download the wall chart below and pin it up. The Burs The kit contains one of each of the following. All burs are available to purchase individually. CAR-7 to CAR-22 — Frank Dental Zirconia Polishing System | Max 20,000 RPM with high-volume coolant (min 50ml/min) A three-grade chairside polishing system — coarse (green), medium (red), fine (yellow) — available in point, cup, and disc patterns to cover every surface geometry. Primarily designed for zirconia but produces excellent results on lithium disilicate and feldspathic porcelain. Always follow the full three-grade sequence for best results, and run with high-volume air/water coolant throughout. The polishing compounds are laboratory-grade and hard wearing. CAR-25 — Amalgam & Metal Crown Removal Bur (C.FD34L.012.FG) | Max 160,000 RPM Cutting-edge geometry specifically optimised for efficient sectioning of metal — amalgam restorations and cast metal crowns. The lower maximum speed makes this well suited to speed-increasing handpieces for controlled, efficient cutting. CAR-26 — Porcelain Bonded to Metal Bur (C.FD8XX.012.FG) | Max 160,000 RPM Carbide geometry optimised for porcelain removal but equally effective on metal — which means a single bur handles PFM crown removal from start to finish without swapping. Also the correct first bur for veneered zirconia crowns: remove the porcelain layer with this before switching to the zirconia cutter (CAR-27) for the substructure. CAR-27 — Crown Cutter Zirconia (D.Z881.012.C.FG) | Max 150,000 RPM Fine grit is counterintuitively the most efficient geometry for cutting zirconia — coarse burs burn and lose cutting ability almost immediately against zirconia's hardness and toughness. For veneered zirconia crowns, remove the porcelain layer first with CAR-26 or a coarse diamond then switch to this bur for the zirconia substructure. Run with coolant at the lower speed limit. CAR-28 — Rugby Ball Zirconia Polisher (D.Z379.023.F.FG) | Max 150,000 RPM The rugby ball profile is ideal for occlusal adjustment of monolithic zirconia crowns. Run with plenty of cooling water — inadequate coolant risks initiating microcracks or pulling crystals from the zirconia surface. Use as part of the full three-grade polishing sequence after adjustment. CAR-29 — Large Tapered Zirconia Polisher (D.Z850.023.F.FG) | Max 150,000 RPM The tapered profile is the right shape for adjusting contact points and internal fit discrepancies on zirconia crowns — areas where the rugby ball cannot access efficiently. Same cooling water and speed requirements as CAR-28. Use within the full polishing sequence. CAR-30 — Composite Removal Bur (C.22ALGK.016.RAL) | Max 30,000 RPM, RA slow handpiece Carbide geometry specifically designed to preferentially cut composite and adhesive while being conservative of underlying tooth structure — the right instrument for removing composite from orthodontic brackets, aligner attachments, and old direct composite veneers. The RA grip and low maximum speed give the control this precise task demands. Download the Crown Adjustment and Removal Bur Kit Wall Chart — for easy organisation and reordering
