Abstract: Methods of making an impression of dental tissue and dental articles (e.g. suitable for dental impression) are described. In one embodiment, the method comprises providing a hardenable composition, comprising a resin system, a filler system, and an initiator system wherein the hardenable composition is a hardenable self-supporting material having sufficient malleability to be formed into a shape. The method further comprises placing said hardenable composition in contact with dental tissue such that an impression of at least a portion of the dental tissue is formed in the hardenable composition. The method further comprises curing the hardenable composition comprising the impression.
