摘要： Improved two component polymerizable polyorganosiloxane compositions are described, particularly for use in making dental impressions, having improved tear strength and wettability. Improved tear strength results from inclusion of a quadri-functional polysiloxane having a vinyl content of 0.16 to 0.24 m-mole/g. Working time is maintained by including sufficient amounts of a retarder composition that delays onset of the vinyl polymerization. Wettability is improved by including a surfactant resulting in a surface contact angle with water at three minutes of less than 50°. The surfactant chosen has an HLB of 8-11, such that the wetting contact angle is achieved within less than two minutes and remains wetting throughout the working time of the impression taking, substantially improving impression quality. A low viscosity impression material is improved and includes a base component and a catalyst component. Both components are siloxane-based materials.

摘要： The present invention includes a dental restorative material for use in for example, class 1 & 2 posterior cavity restorations. The inventive material includes a modified BisGma resin. The invention also includes a method of restoring a damaged tooth that includes the application of bonding agent, applying energy such as by warming the material so that it can be extruded, and placing the material into the tooth cavity.

摘要： A heat pack (30) is provided which contains the reactants for an exothermic chemical reaction. The heat pack (30) having physical contact with or close physical proximity to a package (10) during the ensuing exothermic reaction causes package (10) and material contained within package (10) to be heated.

摘要： The invention provides a method of forming dental restorations, particularly dental crowns. The method involves applying a flexible cement composition to a prepared tooth surface. The composition is polymerized so that it substantially hardens. A composite crown- forming material is dispensed into a substantially transparent plastic matrix. The matrix is placed in the mouth of the patient so that the composite material is molded over the tooth surface. Then, the material is irradiated with curing light, through the matrix, so that it hardens to form a dental crown. The crown has good mechanical strength and is resistant to fracturing and breaking.
