Product Description
Yucera Materials Dental A1A2A3 Preshaded ST-Color Zirconia Block
Natural Color Transition, No Need Dyeing
Pre Shaded Zirconia Blocks made of nanometer medical grade zirconia powder. The powder are firstly compacted by cold isostaticpressing with high compressive strength and then pre-sintered to a certain degree to offer good machinability.
UT zirconia blocks can be used to create crowns, bridges, inlays and veneers of fixed partial denture with different translucency levels and colors.
Zirconia Block Introduction
ST color Pre Shaded Zirconia Blocks
1. super translucency with total light transmission rate >50% (comparable to lithium disilicate)
2. Average strength over 800 Mpa (can be used in a variety of all-ceramic restorations such as onlay/inlay, crown, bridge and so on)
3. Highly accurate Vita standard coloring liquid to meet the requirements of high standard dental restoration
4. Excellent machinability owing to unique shaping technique
5. Top quality medical-grade nanometer zirconia powder
6. Ok for Anterior + Posterior teeth
Yurucheng zirconia block has high strength, excellent permeability and color aesthetic repair effect that suitable for CAD/CAM system and manual system.
Pre Shaded Zirconia Blocks Features
Safety:No irritation,No corrosion,Good bio-compatibility
Beauty:Natural teeth color can be reproduced
Comfortability:Low thermal conductivity,hot and cold changes do not stimulte the pulp
Durability:Over 1600MPa perturbed strength, durable and useful
Sintering
Every batch of zirconia block has gone though a completely sintering test. The sintering methods have a great impact on blocks’ properties, such as translucency, dyeing results, strength, hardness and ageing resistance, which will affect the blocks’ final stability. Therefore, please follow the sintering curve of it.
