Lucitone Digital Dentures Resin vs. Rodin 2.0 Digital Denture Resin

[DentureDank]

Our Lab is currently in the process of making the transition from making dentures analog to going digital. We have an Asiga printer we have ordered and also purchased a Phrozen Sonic Mini 8KS. We also purchased an otoflash curing unit.

My question is, what are the pros and cons of the Lucitone Digital Print and Rodin 2.0 denture resins? Which has the better workflow? Which has better value and aesthetics?

Our lab is having trouble deciding between the two. I don't have as much experience with the rodin resins, but I know the dentsply lucitone resins allow for the digital dentures to be repaired, and they don't have to be polished after they are cured, just lather fuse 3 over the whole thing and it works just as well as a polish. The resin also doesn't have to be rolled or stirred like other resins.

These advantages were why we were leaning towards dentsply resin, but we realized we couldn't use the Phrozen printer or the otoflash curing unit with their resin. Which made us reevaluate, maybe it would be better to use Rodin's resin instead, since all of our supplies are compatible with it.

What are your thoughts? Is the new Lucitone Digital Print resin and its workflow worth it?

Did you ever get feedback on this? I am interested in knowing if the Rodin resin workflow is as good as LDP.

The Rodin material can be cured in the otoflash but the lucitone print requires a Densply curing unit.
I use both resins. I prefer the Rodin over the lucitone. However I now prefer milled dentures over printed and have switched most of my printed cases over to milled. Just my opinion.

Interesting, thanks for your feedback. I am curious to hear what makes you prefer the milled dentures.

Printed dentures were breaking after 6-12 months. Milled dentures are back to the reliability of conventional analogue dentures. I enjoyed the simplicity of printing but patients were getting very upset and it wasn’t worth loosing business.

A post I just made in another thread is relevant here, this was in response to a question about why printed is worse than milled, mechanically speaking:

[P]olymerization occurs in resin prints as well [as in milling blanks], that's what's happening when it's exposed to UV light, monomers and oligomers are cross-linking to form the desired bulk polymer. ...except it's not all polymer, there's a lot of junk in there, too, because a non-negligible proportion of the resin formulation is a highly-UV-reactive photoinitiator agent. Once the curing occurs, all that photoinitiator becomes inert crud bound up in a spongey mass of mostly cross-linked polymers. And there's other non-mechanical components in there as well, fillers and pigments and so on.
Resin is effectively a composite material where a large proportion of the composite is unwanted and unhelpful, but unavoidable. Compare this to a milling blank, which has a much smaller proportion of mechanically-unhelpful components, and more critically, is manufactured in a very tightly-controlled way that optimizes the homogeneity and mechanical effectiveness of the polymer. Resin printing, on the other hand, is a process that bends over backwards to allow polymerization to occur with very small inputs of energy on an extremely short timeline, we're talking about each individual exposure here, vs, you know, polymerization being performed with hours of heating in large batches, or chemically-catalyzed polymerization that doesn't permit the very accurate and controlled polymerization you get with stereolithography. Geometric fidelity of a manufactured good is what the process is built around, for understandable reasons, but the mechanical properties of the final products suffer accordingly.
