Bonding Protocols for Indirect All-Ceramic Restorations
Silica based ceramics (feldspathic, leucite-reinforced, lithium disilicate):
- Try-in restoration. Adjust as needed
- Hydrofluoric-acid etching
- Silane coupling agent
- Composite resin
Non-silica-based (alumina and zirconia):
Adequate resistance and retention form?
- 10-20 deg. TOC
- Minimal OC height = 4 mm for molars
- Minimal OC Height = 3 mm for all other teeth
- OC-FL dimension ratio of 0.4 or greater
Standard Cementation Protocol using:
- Self-adhesive resin cement
- Resin-modified glass-ionomer
- Try-in restoration adjust as needed
- A – Air-particle abrasion using 50-micron aluminum oxide at 2-bar
- P – Phosphate monomer (MDP) air dry
- C – Composite resin (dual or self-cure)
