HONCHON Zirconia Block Instructions Multilayer--SHTML/3D Plus/4D Plus

Before Use

HONCHON Zirconia Blocks are pre-sintered dental zirconia.

Handle with care. Inspect each shipment for damage and do not use damaged discs for dental

restorations. Store HONCHON Zirconia in its original packaging in a cool, dry, temperature-stable environment (between 5°C and 50°C).

Recommended Design Steps

Scanning and Design

Please scan with a high-precision scanner to obtain an accurate date of the restoration model. Design according to the patient's condition and the doctor's requirements.

Milling

Pre-sintered zirconia materials have an inherent shrinkage associated with each production. The shrinkage must be entered into the milling preparation software to ensure the accuracy of the final restoration.

When milling our zirconia, always follow these general guidelines:

·Please determine the incisal side first.

Only use sharp end mills with carbide or diamond coatings

Do not use any restorations that have chips or cracks. Use a handpiece with a diamond-coated drill to remove the unit from the tray. Use a medium-grit rubber polishing wheel to smooth the support area.

·Remove residual zirconia dust with an artist's brush

If using a wet grinder, make sure all zirconia is completely dry before sintering. Air dry for at least 15 minutes before sintering. If wet zirconia is placed in the sintering furnace, it will crack.

Restoration Separation and Cleaning

Separate the restoration from the block using a technician-specific handpiece and grinder. Please use a brush to clean the powder on the surface and inside of the restoration. If the cleaning is not thorough, the powder residue will contaminate the coloring liquid during dyeing, and the powder residue will remain on the surface and inside of the restoration after high-temperature sintering to form white spots, which will have a negative impact on the aesthetics of the restoration.

Coloring

HONCHON multilayer zirconium oxide generally does not require coloring.

Sintering

Put the restoration together with the zirconium beads in a crucible. The bottom of the crucible should be covered with zirconium beads. Make sure the sintering furnace is clean.

Sinter the restoration according to the recommended temperature (see the sintering curve in the attachment at the end). Recommended maximum heating rate: 10°C per minute

Cooling should be performed in a closed furnace without temperature control.

Do not open the furnace before the temperature drops to 80°C to avoid thermal shock.

Grinding and polishing

Use a special zirconium oxide grinder to trim the restoration surface steps: coarse grinding-fine grinding-coarse polishing.

Glazing

After rough processing, external staining and glazing are performed.

Finishing

The restoration is completed.
