Leucite-Reinforced Ceramic

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

Leucite-reinforced ceramic is a tooth-coloured glass ceramic used for inlays and onlays, with strength shaped by composition, processing, and design.

[1][3]

The short answer

Leucite-reinforced ceramic is a glass ceramic used for tooth-coloured inlays and onlays, with its strength affected by its composition and design. Its mechanical behaviour also reflects how the ceramic is processed.

What affects its strength?

Flexural strength can be optimised by changing the ceramic’s composition and processing. Leucite reinforcement is used to modify the glass ceramic’s mechanical behaviour.

[1][3]

Where is it used?

Leucite-reinforced ceramic has been evaluated in posterior partial-coverage restorations and inlays or onlays fixed with resin cement.

[1][3]

How does it compare with other ceramics?

A laboratory comparison tested leucite-reinforced ceramic alongside feldspathic ceramic, lithium disilicate-reinforced ceramic, and indirect resin-based composite restorations.

[1][3]

What happens when it is fitted?

In a 14-year clinical evaluation, restorations were fixed either with self-adhesive resin cement or with an etch-and-rinse adhesive followed by resin cement. Recalls took place after two weeks, two years, four years, and 14 years.

[1][3]

How is fracture risk assessed?

Testing has used 2 mm of occlusal reduction, compressive loading, and a three-dimensional finite-element model to compare maximum principal stress and restoration failure risk across materials.

Frequently asked questions

Were leucite restorations followed for 14 years?

Yes. The clinical evaluation scheduled recalls at two weeks, two years, four years, and 14 years, with 54 restorations assessed at the final recall.
