Dental Ceramics Overview

Dental ceramics possess unique properties for various dental applications, categorized by their type and structure.

Feldspathic Porcelain

Used primarily for metal-ceramic veneers and anterior laminate veneers.
Can be applied in low-stress situations like single-surface inlays.
Not recommended for inlays, onlays, crowns, and bridges due to bruxism concerns.

Aluminous Porcelain

Serves as a core ceramic for anterior crowns and low-stress premolar crowns.
Contraindicated for molar crowns and bridges, as well as in bruxism cases.

Leucite Glass-Ceramic

Suitable for anterior single-unit crowns and laminate veneers.
Can also be used in low-stress premolar applications if high translucency is required.
Not advisable for high-stress situations or bridges.

Lithia Disilicate Glass-Ceramic

Effective for anterior and premolar crowns, and anterior 3-unit bridges.
Can be used for low-stress posterior bridges up to the second premolar.
Should be avoided in high-stress posterior scenarios and bridges involving molars.

Alumina

Functions as a core ceramic for crowns and low-stress anterior bridges.
Not suitable for anterior veneers or high-stress posterior bridges, especially in bruxism.

Glass-Infiltrated Spinel

Used for anterior crowns needing high translucency.
Not recommended for anterior bridges or any posterior applications.

Glass-Infiltrated Alumina

Applicable to both anterior and posterior crowns and short anterior bridge substructures.
High translucency is necessary and contraindicated for anterior veneers and most posterior structures.

Glass-Infiltrated Alumina/Zirconia

Focused on posterior crowns and bridge substructures, extendable to anterior bridge substructures.
Not appropriate for anterior veneers and situations demanding high translucency.

Zirconia (Y-TZP)

Ideal for posterior crowns and bridge substructures up to five units.
Not suitable for anterior applications where high translucency is a requirement.

Zirconia (3Y-TZP)

Limited data available; primarily used for posterior crowns and bridges.
Contraindicated for anterior veneers, crowns, or bridges.

Ce-TZP/Al2O3

Specific for posterior crowns and bridges but lacks extensive clinical data.
Not appropriate for anterior aesthetics requiring high translucency.

4Y-PSZ & 5Y-PSZ

Both types are versatile, applicable for anterior and posterior crowns, veneers, and onlays.
Not suitable for bridges, especially in high-stress areas due to potential failure.
