Abstract: A dental impression device (100) which has a buccal support (1a), a lingual support (1b), and a joining section (1c). The buccal support (1a) is disposed towards the buccal side of a dental arch; the lingual support (1b) is disposed towards the lingual side of the dental arch; and the joining section (1c), which connects the buccal and lingual supports, is disposed posterior in the mouth's no bite region. The supports (1a, 1b) form impression material holding areas which hold and secure dental impression material (9). The supports (1a,1b) and joining section (1c) form an open bite through area through which the lower and upper teeth's occlusal surfaces can make contact. Dental impression material (9) supported in the holding area by the supports is disposed in the open bite through area and is between the occlusal surfaces of the upper and lower teeth. The dental impression is then formed by a person making a closed bite into the impression material.

Abstract: The present invention relates to using a communications device to interface a plain old telephone system (POTS) terminal to a communications network. In particular, it relates to a communications device that appears to the POTS terminal to be a telephone network. Particular aspects of the present invention are described in the claims, specification and drawings.

Abstract: A multipart gypsum casting composition comprising a gypsum composition and a water composition where either the water and/or the gypsum composition contains at least two acids selected from the group consisting of oxalic acid, boric acid, phosphoric acid, citric acid, sodium citric acid, trisodium citric acid, tartaric acid, sulfuric acid, acetic acid, formic acid, malic acid, ascorbic acid and aspartic acid.

Abstract: A dental impression composition, dental impression pre-form and/or pre-mold and method for taking a dental impression that includes a pre-form made of an ethylene vinyl acetate copolymer mixed with a second polymer selected from vinyl acetate, a second ethylene vinyl acetate and a vinyl acetate vinyl alcohol ester. The pre-form softens at a temperature of about 120.degree. F. to 170.degree. F. The composition and method may also include a second pre-form made of a thin separator film sheet of a high molecular weight polycaprolactone, sandwiched between two ethylene vinyl acetate pre-forms.

Abstract: A custom dental tray is prepared by a dentist who manually works a soft dough-like composition of polycaprolactone polymer onto a stone dental cast and allows the polymer to harden to form the custom dental tray. The polycaprolactone polymer has an average molecular weight of from about 35,000 to about 60,000 and a crystalline melting point of from about 120.degree. F. to about 160.degree. F. and which is hard at temperatures of up to about 105.degree. F.
