    摘要: The present invention provides an addition-curable composition containing an inorganic, organic or organometalic compound of palladium in an amount effective to reduce the amount of hydrogen gas evolved in the reaction of the composition. A preferred embodiment is a dental impression material composition comprising: (a) an addition-curable compound; (b) a crosslinker; (c) a platinum-containing catalyst; and (d) a palladium compound. This generally provides a positive gypsum model of, for example, a dental impression that is substantially free of pits.

    摘要: An acid and a water-soluble film former are used as a primer for hard tissue (e.g., dentin). The acid has a pK.sub.a less than or equal to that of phenol and the acid and its calcium salt(s) are soluble in the film former. The primer is free of adhesively detrimental quantities of calcium salts that are not soluble in the film former.

    摘要: A method of dispensing a hardenable dental composition comprising 1) providing a two-part hardenable dental composition, and 2) extruding the composition through a static mixer in fluid communication with a first reservoir containing the first part and a second reservoir containing the second part, wherein a plunger is positioned in each reservoir for simultaneously forcing both parts into the static mixer, extruding the composition through the static mixer, and dispensing the composition, and wherein an extrusion force is applied to the plunger for extruding the composition through the static mixer without the aid of a mechanical advantage provided by an attached or external device. Also disclosed is a method of bonding a prosthetic device to a dental structure using the dispensing method, a device for dispensing the composition using the dispensing method, a kit comprising the device, and the composition used in the dispensing method.
