Study Notes
Feldspathic Porcelain
- Used primarily for metal-ceramic veneers and anterior laminate veneers.
- Appropriate for single-surface inlays and low-stress sites requiring high translucency.
- Not suitable for inlays, onlays, crowns, bridges (except metal-ceramic veneers), and for patients with bruxism.
Aluminous Porcelain
- Serves as core ceramic primarily for anterior crowns.
- Can be used for low-stress premolar crowns.
- Contraindications include molar crowns, bridges, and bruxism.
Leucite Glass-Ceramic
- Suitable for anterior single-unit crowns and anterior laminate veneers.
- Can be applied in low-stress premolar inlays and crowns that require high translucency.
- Should not be used in high-stress situations, for bridges, or in patients with bruxism.
Lithia Disilicate Glass-Ceramic
- Used for anterior and premolar crowns, as well as anterior 3-unit bridges.
- Applicable for anterior laminate veneers and posterior 3-unit bridges up to the 2nd premolar.
- Contraindicated in high-stress posterior situations, for bridges involving molars, and for bruxism.
Alumina
- Functions as core ceramic for crowns and low-stress anterior bridges.
- Can also be used in low-stress posterior bridges.
- Not recommended for anterior veneers, high-stress posterior bridges, and bruxism.
Glass-Infiltrated Spinel
- Primarily used for anterior crowns and situations requiring high translucency.
- Not suitable for anterior bridges, posterior crowns and bridges, and for bruxism.
Glass-Infiltrated Alumina
- Employed for anterior and posterior crowns.
- Suitable for anterior bridge substructures up to 3 units.
- Contraindications include anterior veneers, posterior crowns and bridges, high translucency needs, and bruxism.
Glass-Infiltrated Alumina/Zirconia
- Used for posterior crowns and bridge substructures up to 3 units.
- Can serve as anterior bridge substructures up to 3 units.
- Not suitable for anterior veneers and crowns, high translucency requirements, and for bruxism.
Zirconia (Y-TZP) with Veneering Ceramic
- Primarily used for posterior crowns and bridge substructures up to 5 units.
- Not recommended for anterior veneers, crowns, bridges, high translucency situations, or in bruxism cases.
Zirconia (3Y-TZP) Monolithic
- Utilized for posterior crowns and bridges with limited clinical data available.
- Can be applied for posterior core-ceramic bridges.
- Contraindications include anterior veneers, crowns, and bridges, high translucency needs, and bruxism.
Ce-TZP/Al2O3
- Used for posterior crowns and bridge substructures, though clinical data is lacking.
- Not suitable for anterior veneers, crowns, bridges, high translucency cases, or for bruxism.
4Y-PSZ
