| dental impression materials | Substances or combinations of substances used for making a negative reproduction or impression of the teeth and oral structures for the purpose of producing restorations, prostheses, and dentures, including elastomeric materials, dental plasters, metallic oxide pastes, hydrocolloids, silicone base materials, polyethers, polysulfides, and duplicating compounds. (12 Dec 1998) |

| dental impression technique | Procedure of producing an imprint or negative likeness of the teeth and/or edentulous areas. Impressions are made in plastic material which becomes hardened or set while in contact with the tissue. They are later filled with plaster of paris or artificial stone to produce a facsimile of the oral structures present. Impressions may be made of a full complement of teeth, of areas where some teeth have been removed, or in a mouth from which all teeth have been extracted. (12 Dec 1998) |
| denture impression surface | That portion of the surface of a denture which has its contour determined by the impression; it includes the borders of the denture and extends to the polished surface. (05 Mar 2000) |
| direct bone impression | An impression of denuded bone, used in the construction of subperiosteal denture implants. (05 Mar 2000) |
| duodenal impression | A hollow on the visceral surface of the right lobe of the liver alongside the gallbladder, marking the situation of the duodenum. Synonym: impressio duodenalis. (05 Mar 2000) |
| oesophageal impression | The marking of the oesophagus on the back of the left lobe of the liver. Synonym: impressio oesophagea. (05 Mar 2000) |
| trigeminal impression | A depression on the anterior surface of the petrous portion of the temporal bone, near the apex, lodging the trigeminal ganglion. Synonym: impressio trigeminalis. (05 Mar 2000) |
| final impression | In dentistry, the impression that is used to make the master cast. (05 Mar 2000) |
