Abstract: The invention relates to a radiation curable composition for additive-manufacturing processes, the composition comprising (meth)acrylate component(s) not comprising an urethane moiety having a molecular weight Mw of at least 1,000 as Component A1, photo initiator as Component B, red, yellow or orange dye or combination thereof as Component C, blue dye having a light absorption band in the range of 350 to 420 nm as Component D, and optionally stabilizer as Component E. The invention further relates to a process of producing an elastomeric 3-dim article from the radiation curable composition in an additive-manufacturing process and the obtained elastomeric 3-dim article.

Abstract: A customized orthodontic bracket system is provided. The system can include a bracket having a customized bracket bonding pad for bonding the bracket to a tooth of a patient and a bracket slot adapted to receive a customized archwire. The customized archwire is adapted to be positioned in the bracket slot to form a precise bracket slot-archwire interface. The bracket slot and the archwire when positioned in the bracket slot can be positioned substantially adjacent the tooth surface to reduce induced vertical error in tooth positioning. The bracket slot can be configured to have a bracket slot width substantially matching a cross-section of the archwire to reduce torque rotation around an axis of the archwire when positioned therein to further enhance end-of-treatment tooth positioning and reduce overall treatment time.
