OCTOdent Bonding Protocol — Chairside Reference
The 6 steps
Corded electric air gun or air/water syringe (air only). Drive
pooled resin out of the intaglio.
Soft toothbrush dipped in 91%+ IPA. Dip–brush–dip–brush. No
soaking. Dry.
50 µm aluminum oxide, **1.5–2 bar**, ~10 mm distance, 10–15 sec
per surface. Stop when uniformly matte.
Print layer lines visible in intaglio = clean. Glossy or smooth =
uncured resin remaining. Repeat steps 2–3.
Clearfil Ceramic Primer Plus, one coat, dry until matte (not
glossy). Handle from the occlusal after this point.
- Pumice. Selective enamel etch 37% H₃PO₄ × 15–30 sec. Rinse. Dry.
- Panavia V5 Tooth Primer × 20 sec. Dry.
- Panavia V5 paste from automix. Seat with steady pressure.
- **Tack cure 3–5 sec** per surface. Remove excess with floss and
explorer.
- **Final cure 10 sec** per surface at ≥1000 mW/cm². **20–40 sec**
for thick or opaque posterior crowns.
- Glycerin gel + 10 sec per surface at margins.
Never
- Hydrofluoric acid on 3D-printed composite hybrid resin.
- Self-adhesive cement on non-retentive preparations.
- Universal adhesive + dual-cure cement across brand lines
without a dual-cure activator.
- Cementation without effective isolation.
- Tack cure beyond 5 seconds.
- Crown in ethanol longer than 10 minutes.
Isolation — preferred to fallback
1. Rubber dam (best). 2. DryShield / Isolite (acceptable).
3. Cotton rolls + retraction cord (fallback; attentive technique).
If margin is bleeding: stop, hemostasis, rinse, re-isolate. Blood
on an abraded intaglio = re-abrade and re-prime.
