Ceramic-Polymer Network

A porous ceramic framework filled with resin composite creates a dental restoration material with both inorganic and organic components.

[1][3]

The short answer

Ceramic-polymer network materials pair a porous ceramic framework with an interpenetrating resin composite for dental restorations.

What is a ceramic-polymer network?

The two connected parts of the material
PartRole
Ceramic frameworkA porous ceramic scaffold forms one part of the network.[1][3]
Resin compositeResin composite interpenetrates the ceramic framework.[1][3]

Factors linked to mechanical performance
FactorWhy it matters
Ceramic scaffoldIts material and structure affect mechanical properties.[1][3]
Pore characteristicsPorosity, shape, size and connectivity affect mechanical performance.[1][3]

[1][3]

Which properties affect performance?

Mechanical properties depend on the ceramic scaffold, its structure, fabrication method, resin composition and resin-ceramic bonding. Porosity, pore shape, pore size and pore connectivity also affect performance.

[1][3]

Where can this material be used?

Polymer-infiltrated ceramic networks are used for dental restorations. Research on single-tooth restorations has examined their survival and complications over observation periods of up to three years.

[1][3]

How does it differ from ceramics and composites?

Ceramics and composites are widely used dental materials. A ceramic-polymer network combines features of both through its ceramic framework and resin composite network.

[1][3]

What controls the material's behaviour?

Material behaviour is tied to how the ceramic scaffold is made, how resin enters it and how the two parts bond. Three-dimensional printing and freeze-casting can control pore characteristics and structure.

[1][3]

What limits clinical use?

Low flexural strength and suboptimal aesthetics can limit clinical application. Survival and complication rates have been examined for single-tooth ceramic-network restorations over up to three years.

[1][2][3]

Frequently asked questions

What makes a ceramic-polymer network different?

It has a porous ceramic framework and an interpenetrating resin composite, so its properties depend on both parts and their bond.
