Lithium Silicate Ceramic

By the Dental Nation clinical team — a licensed dental group practising in the UAE

Lithium-silicate ceramics provide tooth-coloured indirect restorations with selectable translucency, while zirconia-reinforced forms offer an alternative.

[1][2]

The short answer

Lithium-silicate ceramics are glass-based restorative materials related to lithium disilicate, with similar indications and available zirconia-reinforced forms. They are used when a tooth-coloured indirect restoration is required.

What is lithium-silicate ceramic?

Ceramic family comparison
MaterialRecorded property
Lithium disilicateFlexural strength is reported at 250 to 400 MPa[1][2]
Zirconia-reinforced lithium silicateContains 10% dissolved zirconia[1][2]

[1][2]

What properties does it have?

Lithium disilicate has low, medium, and high translucency forms. It is stronger than other glass-based ceramics and more translucent than zirconia, although wear and milled-surface roughness are recognised issues.

[1][2]

Where is it used?

These ceramics are used for indirect restorations, including full-coverage crowns and anterior restorations where tooth-coloured appearance matters.

[1][2]

What are the alternatives?

Lithium silicate and zirconia-reinforced lithium silicate have similar properties and indications. Zirconia is stronger in some applications, while lithium disilicate provides greater translucency.

[1][2]

What does the material mean for a restoration?

A clinician can select among translucency levels and ceramic families to match the restoration’s appearance and functional demands. The material is made for indirect, tooth-coloured restorations.

[1][2]

What can happen over time?

Clinical failure can involve microorganism infiltration, recurrent caries, pulpal lesions, periodontal inflammation, cement exposure, fracture, or chipping. A systematic review reported a 97.6% survival rate for lithium disilicate crowns in a cited critical review.

Frequently asked questions

Is lithium disilicate more translucent than zirconia?

The material review describes lithium disilicate as more translucent than zirconia, while zirconia can provide higher strength in selected applications.
