HT VS ST Zirconia Block

HT Zirconia Block

HT zirconia block is a high-transparency zirconia ceramic processed by a special process. It significantly improves light transmittance while retaining high strength properties. It is widely used in aesthetic restoration of anterior teeth (such as all-ceramic crowns, veneers, bridges)

HT Zirconia Block Advantages:

High strength: suitable for posterior tooth restoration, able to withstand greater bite forces.

Excellent biocompatibility: non-irritating to human tissue, safe and reliable.

Abrasion resistance and chemical stability: hardness close to natural teeth, wear-resistant and corrosion-resistant.

High cost-effectiveness: relatively low price, suitable for routine restoration needs.

Disadvantages:

Limited aesthetic performance: low light transmittance, the aesthetic effect of anterior tooth restoration is not as good as high-transmittance zirconia.

Single color: usually a single-layer structure, it is difficult to simulate the color gradient of natural teeth.

Applicable scenarios:

Posterior tooth restoration (crown, bridge).

Cases with low aesthetic requirements.

ST Zirconia Block

ST Zirconia block is suitable for restorations with extremely high aesthetic and functional requirements (such as all-ceramic crowns, veneers, long-span bridges, etc.)

ST Zirconia BlockAdvantages:

Multi-layer color gradient: can simulate the color change of natural teeth, excellent aesthetic effect.

High light transmittance: the high-transmittance zirconia layer in the anterior tooth area provides a natural optical effect.

High strength: the high-strength zirconia layer in the posterior tooth area is suitable for functional restoration.

Versatility: suitable for anterior and posterior tooth restoration, taking into account both aesthetics and function.

Disadvantages:

Higher price: multi-layer structure and high permeability materials are more expensive.

Complicated processing: more sophisticated design and sintering process are required.

Applicable scenarios:

Aesthetic restoration of anterior teeth (crowns, veneers).

Full dentition restoration (both aesthetics and function).
