Addressing Customer Concerns with Zirconia: Solutions and Support
1. Handling and Storage Issues
Problem: Zirconia materials are sensitive to moisture and temperature. Improper handling and storage can lead to contamination or changes in material properties.
Solution:
Proper Storage: Store zirconia discs and blocks in a cool, dry place, preferably in airtight containers to prevent moisture absorption. Regularly check the storage environment for temperature fluctuations and humidity levels.
Careful Handling: When handling zirconia products, use clean, dry gloves to avoid contamination. Avoid direct contact with any substances that may compromise the material, including oils or dust.
2. Machining Challenges
Problem: Machining zirconia requires precision and specific tools. Improper milling can lead to cracks or compromised restorations.
Solution:
Use Appropriate Equipment: Ensure that your milling machine is compatible with zirconia materials and equipped with suitable diamond burs designed for zirconia. Regularly maintain and calibrate your equipment for optimal performance.
Adjust Milling Parameters: Follow the manufacturer’s guidelines for milling parameters, including speed and feed rates, to avoid excessive heat generation and ensure a smooth finish.
3. Sintering Issues
Problem: Inconsistent sintering can affect the strength and translucency of zirconia restorations.
Solution:
Consistent Sintering Temperature: Monitor and maintain the recommended sintering temperature, typically around 1530°C, using a high-quality sintering furnace. Avoid rapid temperature changes to prevent thermal shock.
Proper Sintering Cycle: Use an established sintering cycle tailored to the specific zirconia material. Ensure the furnace is calibrated correctly to achieve uniform heating.
4. Color Matching Difficulties
Problem: Achieving the desired shade can be challenging due to variations in zirconia coloration and translucency.
Solution:
Use Pre-Shaded Zirconia: Consider using pre-shaded zirconia blocks that match the intended shade, such as Honchon’s HTP colored blocks. This can simplify the process of achieving a natural appearance.
Consult Shade Guides: Utilize shade guides and color-matching tools to ensure the selected zirconia material matches the surrounding teeth.
5. Adhesive Bonding Problems
Problem: Bonding zirconia to natural teeth or other materials can be difficult, affecting the longevity of restorations.
Solution:
Surface Treatment: Prior to bonding, treat the zirconia surface with a suitable primer or bonding agent to enhance adhesion. This can significantly improve the bond strength between zirconia and other materials.
Follow Bonding Protocols: Adhere to established bonding protocols and use recommended adhesive systems that are compatible with zirconia.
6. Patient Sensitivity and Comfort
Problem: Some patients may experience discomfort or sensitivity with zirconia restorations.
Solution:
Proper Fitting: Ensure that the zirconia restoration is properly fitted and contoured to avoid occlusal discrepancies that could cause discomfort.
Patient Education: Educate patients about the benefits of zirconia, including its biocompatibility and reduced risk of gum irritation compared to metal-based restorations.
