Abstract

Described are organopolysiloxane compositions that are capable of cross-linking and / or of hardening by polyaddition reactions so as to produce elastomers or materials made of silicone. Further described, is how the composition is useful for making a dental impression in the context of preparing prostheses.

Description

technical field [0001] The field of the invention is that of organopolysiloxane compositions which can be crosslinked and / or cured by polyaddition reactions to form silicone materials or elastomers, which are especially useful in A dental impression (empreinte) is taken when making a prosthesis. These silicone materials or elastomers are used to take intraoral impressions for dental prostheses such as crowns, inlays or dental devices. Background technique [0002] In this description the expression "taking an impression (prise d'empreintes)" is understood to be limited: it refers not only to the operation of taking an impression of any object and of any shape in order to obtain a model especially made of plaster; but also the reconstruction Or the operation of duplicating a model especially made of plaster. In this specification the expression "taking a dental impression" is understood to be limited: it does not only refer to an operation in which a dental impression is ta...
