3. Keys to Achieving Consistent Color and Translucency
Aesthetic excellence in zirconia restorations depends not only on material selection but also on process control and proper handling. Ivoclar has integrated several smart innovations to help labs achieve consistent optical results—chief among them is the Smart Disc Design.
3.1. Understanding Smart Disc Design
Ivoclar’s “Smart Disc Design” concept is simple yet remarkably effective. Regardless of the disc’s thickness—whether 14 mm, 25 mm, or any size in between—the critical zones remain constant:
- 3 mm incisal layer
- 4 mm transition layer
This uniformity allows technicians to position every restoration consistently, without major adjustments between different disc sizes.
3.2. Proper Disc Positioning for Accurate Color Results
To achieve the intended color and translucency according to Ivoclar’s shade guide, follow these guidelines:
- Position anterior restorations 1.5–2 mm below the top of the disc
- Position posterior restorations 2–2.5 mm below the top of the disc
This ensures the most natural gradient from body to incisal and prevents restorations from appearing overly bright or too opaque in undesired areas.
4. Furnace Calibration – The Key to Optical Quality
A seemingly minor factor that has a major impact on the aesthetic outcome of zirconia is sintering furnace temperature and calibration.
4.1. Why Regular Calibration Is Essential
Zirconia is highly temperature-sensitive. Slight variations between different furnace brands can lead to noticeable differences in color tone and translucency after sintering.
Regular calibration ensures:
- Proper sintering temperature according to Ivoclar’s specifications
- Reduced shade deviation between firing cycles
- Consistent gloss and translucency across restorations
5. Conclusion
As digital dentistry continues to evolve, material flexibility and stability have become critical factors for achieving optimal efficiency and predictable outcomes in modern labs.
