Fast polishing results required – obviously without compromise! But how can you achieve an efficient high luster polish on monolithic ceramic restorations? These 5 tips ensure quick polishing action and brilliant results.
Monolithic restorations made from high-strength ceramics such as zirconium oxide and lithium disilicate have become well established in both dental offices and laboratories – primarily due to their efficient fabrication. The final high luster polish determines the quality of the final result.
Tip 1: Use material-specific polishing systems
Different monolithic ceramics require tailored polishing protocols. While zirconium oxide requires the use of special diamond polishing pastes due to its high hardness, lithium disilicate is also polished with diamond pastes – but using a formulation adapted to the material with more moderate abrasiveness.
Material-specific polishing pastes are more efficient than universal polishing pastes and lead to reproducible results. While zirconium oxide requires the use of special diamond polishing pastes due to its high hardness, lithium disilicate is also polished with diamond pastes – but using a formulation adapted to the material with more moderate abrasiveness.
Tip 2: Pre-polishing as a quality foundation
Pre-polishing with suitable silicone polishers removes processing marks and creates the basis for effective high luster polishing. This step enhances the effect of the subsequent diamond polishing paste and significantly reduces total polishing time.
Tip 3: Adjust rotational speeds according to the material
Controlled rotational speeds prevent thermal stress on the restoration. For zirconium oxide, a maximum of 15,000 rpm is recommended; for lithium disilicate, lower values apply. Caution: Overheating can lead to microcracks and material changes that compromise long-term stability.
Tip 4: Occlusal surface polishing for functionality
Polishing the occlusal surfaces is especially important for monolithic restorations. Inadequately polished occlusal areas can lead to increased wear on antagonists. A systematic approach to all functionally relevant surfaces ensures optimal clinical performance.
Tip 5: Systematic approach for consistent results
A methodical approach from one side of the restoration to the other prevents uneven polishing and ensures consistently high surface quality. For complex geometries, small polishing brushes support the processing of areas that are difficult to access.
Additional note: Glaze and pre-polishing
For glazed monolithic restorations, pre-polishing before glaze firing is recommended. Glaze layers can wear off; a polished surface underneath ensures long-term protection of the antagonist.
Conclusion: Efficiency through organization
Fast polishing in dental offices and labs results from a methodical approach and material-appropriate techniques. The combination of sound material knowledge, adjusted parameters, and high-quality surface finishing enables reproducible high luster polishing of dental restorations with optimal time efficiency.
