Abstract

The invention relates to a process of taking a dental impression, the process comprising the steps of providing a radiation-curable dental impression composition, placing the radiation-curable dental impression composition in contact with dental tissue, applying radiation to the radiation-curable dental impression composition, letting the radiation-curable dental impression composition cure, removing the cured dental impression composition from the dental tissue, the radiation-curable dental impression composition comprising mercapto-functional polyorganosiloxane(s), VQM resin(s), photo-initiator(s) for initiating a curing reaction between, and optionally filler(s). The invention also relates to a cured dental impression obtained by radiation curing the radiation-curable dental impression composition, a kit of parts containing the radiation-curable dental impression composition and a dental impression tray filled with the radiation-curable dental impression composition.
