3Dresyn OD-Clear BIO for rigid night guards & surgical guides

Rigid clear dental resin for surgical guides and night guards

Product description

3Dresyn OD-Clear BIO is a rigid, transparent biocompatible dental photopolymer resin designed for the production of clear night guards and surgical drill guides requiring high mechanical strength, dimensional accuracy and durability during clinical use.

Intended use

Intended for professional use in vat photopolymerization (SLA, DLP and LCD) additive manufacturing for dental applications such as surgical guides and rigid night guards.
Final suitability of printed parts must be validated by the user according to the specific clinical application, processing conditions and applicable regulatory requirements.

Typical applications

Dental surgical drill guides
Implant placement and positioning guides
Clear rigid night guards
Dental appliances requiring high rigidity and transparency
