Dental resins
Dental models, surgical guides and splints; some grades are biocompatibility certified.
What is Dental resins?
Dental resins are special photopolymers developed for orthodontic models, implant surgical guides, night guards and temporary restorations. For intraoral use, only resins with the relevant biocompatibility certification and validated workflows should be used.
