I've experimented with multiple resins over the past couple years. For an interim (prototype) denture we use the 3D+ Nextdent base resin and the CBMFH Nextdent tooth resin. I tell clients this should only be used as an interim denture/prototype, but I have seem them last longer than a year. A plus side is that we can easily reprint at a low cost.
Dentsply Lucitone base is by far the best base resin on the market (now available on the Asiga and not just Carbon). The resin is lightweight, as strong as a traditionally injected denture, and I trust the longevity like I would with a milled or injected base. We mill teeth for all definitive denture cases. Aesthetics end up beautiful. I've experimented with different milled denture bases from Dentsply, Avadent and White Peaks. They are all comparable but I prefer the overall natural look of the Avadent puck.
NextDent released CROWNTEC that would be a good printed option for denture arches or any temporary crown or full arch prototype. Dentsply also released tooth colored resins similar to the strength of a traditional IPN tooth. I think Dentsply resin is only available on the Asiga and Carbon at this time.
