The set contains 24 zirconia crowns for upper primary central and lateral incisors in sizes 1-6, one of each size.

Key features of Shinhung zirconia crowns:

1. High Retention
Enhanced retention due to a sandblasted internal surface improves compatibility and bond strength with GI and RMGI cements. Sandblasting maximizes surface adhesion.

2. Minimal Thickness
Reduces chairside time, increasing efficiency for both the dentist and the patient.

3. Natural Color and Translucency
Subtle matching of natural color and translucency – ideal for primary teeth.

4. Wide Open Gingival Margins
Designed for easy seating and optimal gingival preservation.

During the procedure, it is difficult to completely avoid saliva or blood contamination while trying on crown sizes or checking if tooth preparation is complete.

• If the internal surface of the definitive crown becomes contaminated, it is very difficult to clean it completely.

• Contamination of the crown's interior directly affects the success or failure of cementation.

• The use of a try-in crown completely eliminates the risk of contaminating the definitive crown.

• Used try-in crowns can be reused after autoclaving.

• Even repeated sterilization and reuse do not affect their durability.
