Application Case: Crystallization Treatment of Zirconia Dentures

Process Flow:

Data Acquisition: Use an intra-oral scanner to obtain a three-dimensional digital model of the patient's mouth. Alternatively, take a traditional silicone impression and convert it into a digital model.

Design of Restoration: Based on the digital model, design a zirconia all-ceramic crown suitable for the patient in CAD software, ensuring correct occlusion and natural aesthetics.

Cutting of Zirconia Block: Import the designed digital model into the CAM system. Place a suitably sized zirconia preform block into the CNC machine and automatically cut out the zirconia coping according to the design file.

Coping Pretreatment: Clean the cut zirconia coping to remove residual cutting particles. Perform sandblasting on the zirconia coping to increase surface roughness and improve adhesion with subsequent porcelain layers.

Furnace Preparation: Place the pretreated zirconia coping on a dedicated tray, ensuring sufficient clearance between each crown for uniform microwave distribution. Follow the equipment instructions to place the tray smoothly into the microwave crystallization furnace.

Set Crystallization Parameters: Input the preset crystallization program on the control panel of the microwave crystallization furnace, including heating rate, maximum temperature, holding time, and other parameters. After confirming that all set values are correct, close the furnace door.

Start Crystallization Program: Start the microwave crystallization furnace to begin the crystallization process. Microwave energy rapidly penetrates the zirconia coping, raising its overall temperature and promoting grain growth and crystalline structure transformation.

Cooling: After crystallization is completed, naturally cool to room temperature according to the preset cooling curve. The furnace door should remain closed during cooling to avoid stress concentration caused by sudden temperature drops.

Retrieve Finished Product: When the zirconia crown is completely cooled, carefully remove the finished product. Inspect the appearance quality of the zirconia crown to ensure no cracks, deformations, or other issues.

Post-processing: Perform necessary grinding and polishing on the cooled zirconia crown to make its surface smooth and flat. Depending on needs,美化 treatments such as staining and glazing can also be performed.

Try-in and Adjustment: Try the zirconia crown in the patient's mouth, checking occlusion and aesthetics. If necessary, make minor adjustments to achieve the best results.

Final Cementation: Use appropriate adhesive to fix the zirconia crown onto the affected tooth, ensuring secure bonding.

Through the above steps, leveraging the technical advantages of the microwave crystallization furnace, a beautiful and durable zirconia all-ceramic crown is ultimately provided to the patient. This process not only improves the quality of the restoration but also significantly shortens the production cycle, providing patients with faster service.
