Abstract: The invention relates to a process of processing a radiation-curable composition with an additive-manufacturing technique comprising a radiation-curing step, the radiation-curable composition comprising mercapto-functional Component A comprising at least three mercapto moieties, crosslinker Component B with at least three vinyl or allyl moieties, photo-initiator(s) Component C for initiating a curing reaction between Component A and Component B, wherein the radiation-curable composition does not comprise urethane (meth)acrylate oligomers in an amount of more than 4 wt. % with respect to the whole composition. 3-dim articles which can be produced are typically transparent and have adequate mechanical properties. The radiation-curable composition is in particular useful for producing clear-tray aligners for dental and orthodontic purposes.

Abstract: A process for taking a dental impression and/or conducting a dental retraction. The process includes the steps of: (a) providing a composition (A) having the consistency (a1), composition (A) including curable components, and a catalyst suitable to initiate or catalyze the curing of the curable components, composition (A) being contained in a device, (b) applying a portion (I) of composition (A) with a consistency (a2) into the sulcus of a tooth, (c) applying a portion (II) of composition (A) with a consistency (a1) in contact with composition (A) applied in step (b), (d) removing portion (I) together with portion (II) of composition (A) from the surface of the tooth, consistency (a2) being higher than consistency (a1).
