Printed hybrids: proven bonding stack

I’m running a Trilor (1.2 mm) frame with OnX Tough 2 teeth and Flexcera Gingiva on an Asiga MAX 385 — 50 µm Al2O3 at 2 bar, MDP/HEMA primer, 20 min glycerin post-cure. Has anyone got a validated sequence or tech sheet that’s held up past 12 months chairside to keep the interface from creeping or delaminating?

“held up past 12 months chairside to keep the interface from creeping or delaminating?” Same goal here — the single change that fixed it for us was tribochemical silica on Trilor (CoJet/Rocatec 30 µm at about 2.5 bar), then a straight silane hit before your MDP. We’re 18–24 months no lift on MAX 385 cases — have you tried that sequence?

, MDP/HEMA on Trilor kept creeping for us; what finally stuck was swapping to Visio.link on the frame after a hotter blast (110 µm Al2O3 at about 2.5 bar, 8–10 s, about 10 mm), then a thin Crea.lign opaquer before printing Flexcera and extending the glycerin post-cure on the MAX 385 to 30 min. We’re 18–22 months chairside with OnX Tough 2 on that stack. Caveat: keep the blast short or you’ll fuzz the fibers — if you’d rather avoid that, do you have access to Rocatec like @kevin_ross55 instead?

One change that stopped our interface creep was a quick dry-heat on the Trilor before priming: 120°C for about 10 minutes, then immediate steam clean and hot-air dry, and go straight to the adhesive. Do your ‘20 min glycerin post-cure’ not just at the end — paint glycerin over the primer/opaquer and flash so the OIL doesn’t sit there. On a 1.2 mm frame, keep it supported while heating or you’ll get a tiny warp, .
