Star Zirconia SHT Block

STAR Zirconia SHT Block is a super-high translucent zirconia designed for superior esthetics and strength in dental restorations. With its exceptional translucency, it is ideal for anterior crowns, veneers, and bridges, replicating the natural beauty of real teeth.

Manufactured using advanced multi-layer technology, STAR SHT Blocks offer seamless gradient color and excellent mechanical stability. Each block is precisely formulated for consistent sintering results, outstanding shade accuracy, and optimal compatibility with open CAD/CAM milling systems.

1. Case Design
• Begin by obtaining a digital scan or impression of the patient’s prepared tooth using an intraoral scanner or by scanning a physical model.
• Import the scan into dental CAD software and design the required restoration (crown, bridge, veneer, or coping) according to the clinical requirements.
• Ensure the margins, occlusion, and anatomy are accurately defined before proceeding to milling.

2. Milling Procedure
• Select the appropriate STAR SHT Zirconia Block shade and size for the restoration.
• Secure the zirconia block in a compatible CAD/CAM milling machine.
• Mill the restoration based on the finalized CAD design following the machine manufacturer’s milling parameters for zirconia.
• Carefully remove the milled restoration from the blank and detach the sprue.

3. Sintering
• Place the milled zirconia restoration in a zirconia sintering furnace.
• Sinter the restoration according to the recommended temperature and time instructions provided by the zirconia manufacturer.
• Allow the restoration to cool gradually to avoid structural stress or cracking.

4. Finishing and Characterization
• After sintering, check the restoration for surface smoothness and marginal integrity.
• Perform minor adjustments using suitable zirconia finishing burs if necessary.
• Polish or apply stain and glaze to enhance the final aesthetics and surface finish.

5. Clinical Try-In
• Place the restoration in the patient’s mouth to evaluate fit, marginal accuracy, occlusion, and shade match.
• Make any necessary adjustments to ensure proper function and patient comfort.

6. Cementation
• Clean and prepare the internal surface of the zirconia restoration according to recommended zirconia bonding protocols.
• Use a suitable dental cement for zirconia restorations.
• Seat the restoration properly with adequate pressure, remove excess cement, and verify occlusion and final placement.

7. Storage
• Store unused STAR SHT Zirconia Blocks in a clean, dry environment.
• Protect from moisture, contamination, and physical damage before use.
