Adhesion and restoration guides

Protocol on ZIRCONIA (internal surface) Cleaning specific cleaner (Ivoclean — Ivoclar Vivadent) Air dry Airborne-particle abrasion (sandblasting) Aluminum oxide (Al₂O₃) 30–50 µm Pressure: ~1–2 bar Post-abrasion cleaning Air or rinse + dry MDP...

Protocol on the CERAMIC (internal surface) Cleaning Options: Phosphoric acid 37% — 10–15 s → rinse → dry Purpose: remove contaminants Hydrofluoric acid etching Lithium disilicate: 5–10 s Feldspathic: 20–60 s Do...

Protocol Isolation Ideal: rubber dam Avoid contamination Cleaning Pumice or brush No fluoride-containing pastes Time: ~10–15 s Acid etching (if total-etch) Phosphoric acid 35–37% Time: 10–15 seconds Rinse — 15 seconds Abundant water Drying Do not desiccate Dentin moist...

Protocol Isolation Ideal: rubber dam Avoid contamination Cleaning Pumice or prophylaxis No organic residues Acid etching Phosphoric acid 35–37% Time: 15–30 seconds Rinse — 15 seconds Abundant water Remove all acid Dry — 15 seconds Air Appearance: frosted white Adhesive...

Adhesion = union between two different surfaces (tooth / material) Works by: Micromechanical Chemical Or a combination of both The key to all adhesion (this defines everything) There is no...
