摘要： 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).

摘要： A device for use in retracting a gingiva from a human tooth by widening a gingival sulcus with a dental composition. The device comprises a cannula with a free end having an opening for dispensing the dental composition. The free end is shaped to be inserted with its front in the entry of the gingival sulcus, and to laterally displace the gingiva from the tooth as the cannula is moved in the gingival sulcus. The invention may help to achieve a reliable and cost effective gingival retraction treatment.
