Abstract: Described are new pasty masses that are suitable as insert material for widening the gingival sulcus. These retraction materials contain a paste-forming agent, superabsorber particles and at least one astringent. Surprisingly, it was shown that upon contact with fluid of such a retraction material paste formulation, for one, a volume expansion is occurs due to absorbed fluid and for another, a part of the superabsorber is diffused out of the paste and/or dissolved out and that this diffused and/or dissolved part in turn leads to the immediate thickening, bonding and/or coagulation of surrounding fluids such as saliva, blood and wound secretions. The effect is hemostasis, as well as widening of the sulcus.

Abstract: A method for sterilizing medical single-component or multi-component impression materials that can harden, and a two-component impression material. In a first step of the method, the components of the impression materials that have not hardened are introduced into a primary packaging. In a second step, the primary packagings, with the components contained therein, are sterilized by heat sterilization. In a third step, the sterilized components in the primary packagings are introduced into a secondary packaging. In a fourth step, this secondary packaging is sterilized by means of a suitable gas sterilization, irradiation sterilization, and/or by means of sterilization in an autoclave, so that the activity and the viscosity of the components are not changed.
