About denture resins
3D printing denture resin prints the resin base of a complete denture straight from the design file, without moulds, cutting tools or fixtures.
A 3D printing resin is a liquid, light-sensitive resin that a printer hardens layer by layer. The glossary describes stereolithography in dentistry as the layering of light-reactive resin to make replicas of casts and devices. Printing in a vat of resin has become the benchmark in dental practice, and comes in three technologies: SLA, DLP and LCD.
When the resin is exposed to light of a specific wavelength, photoinitiators in it start the reaction that joins the monomers into polymer chains.
How the types of printing resin differ
- Model resin — For models that stay on the bench, not for parts worn in the mouth.
- Denture resin — For denture bases.
- Castable resin — A pattern for casting, not a part that is kept.
- Temporary crown resin — For crowns and bridges worn for a limited time.
- Surgical guide resin — For implant guides.
- Night guard resin — For removable occlusal devices such as splints.
- Permanent Crown & Bridge Resin — Filed for printed crowns and bridges that stay in place, where temporary crown resin is filed for provisionals.
The shelf also holds resin for permanent crowns and bridges; no source on the allowed list describes it yet, so it has no entry here.
What to look at when choosing a printing resin
Wavelength: photoinitiators are activated between 365 and 405 nm depending on the technology and the printer. A resin from one brand may not print on a printer from another brand if the wavelengths do not match.
After printing: the part is rinsed with a resin solvent to remove unpolymerised resin, dried, cured again in a light device, and its supports are removed. The rinse is generally 99% isopropyl alcohol.
Print settings: build orientation, layer thickness and post-curing all affect the printed result.
