Print-to-Seat Protocol
Clinical Protocol
Print-to-Seat Protocol
The complete chairside workflow from printed restoration to bonded crown in the patient's mouth. Ten steps across two phases.
Never do any of these
- Hydrofluoric acid on 3D-printed composite hybrid resin
- Self-adhesive cement on a 3D-printed restoration (use a primer + dual-cure resin cement)
- Soak a printed crown in IPA or ethanol beyond manufacturer wash time (degrades bond)
- Mix universal adhesive with an incompatible dual-cure cement
- Cement without effective isolation (dam preferred)
- Skip intaglio air-abrasion — it is required for adequate bond strength
Phase 1
Chairside Post-Processing
Preparing the printed restoration for bonding. OCTOdent's chairside protocol; see the downloadable PDF for the manufacturer-validated in-chamber alternative and full disclaimers.
Remove excess uncured resin
High-volume electric air gun or operatory air/water syringe on air-only. Drive pooled resin out of the intaglio before it sets.
Scrub with IPA or ethanol
Soft dental toothbrush in >91% IPA or >95% ethanol. Scrub the intaglio vigorously. Do not soak.
Dry thoroughly with air
Residual solvent inhibits polymerization. Blow clean across all surfaces including margins and intaglio corners.
Air abrasion
50 µm aluminum oxide at 1.5–2 bar (22–29 psi), ~10 mm distance. Abrade until the intaglio shows uniform matte finish with visible print layer lines.
Glycerin + chairside cure
Apply glycerin gel (Liquid Strip or equivalent) over all surfaces of the crown to eliminate the oxygen-inhibited layer. Cure with a broad-spectrum LED curing light at multiple angles. (PubMed Article)
After cure, rinse glycerin off with warm water and dry thoroughly before the next step — residual glycerin will interfere with polishing and bonding. Chairside cure is not formally validated by any resin manufacturer — see PDF for disclaimer and cautions.
Polish external surfaces
Polish external and occlusal surfaces only — NOT the intaglio, which must stay rough for bonding. Most quality composite polishing systems work.
Phase 2
Cementation
Default workflow below is Kuraray Panavia V5 (OCTOdent's recommended cement). Using a different cement? Follow your cement's IFU — the principles (10-MDP primer, dual-cure, dam isolation, calibrated cure light) transfer, but timing and adhesive sequence differ.
Prime intaglio of restoration
Apply 10-MDP primer (Clearfil Ceramic Primer Plus). One coat, dry thoroughly with oil-free air until matte.
Isolate, prep tooth, apply tooth primer
Rubber dam preferred. Pumice, selective enamel etch, apply Panavia V5 Tooth Primer per Kuraray IFU.
Load cement, seat crown, tack cure
Extrude thin even layer of Panavia V5 into intaglio. Seat with firm apical pressure. Tack-cure 3–5 sec/surface, remove excess with explorer + floss.
Final cure + oxygen-barrier margin re-cure
Final light cure 10 sec/surface (20–40 sec for thick or opaque posteriors). Apply an oxygen-barrier gel (Oxyguard II or any glycerin) along the margins and re-cure 10 sec to eliminate the oxygen-inhibited cement layer.
