Abstract: Improved very high viscosity (putty) two component polymerizable polyorganosiloxane composition for use in making dental impressions, having improved tear strength, handling 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. Handling is improved by the addition of a very high viscosity linear vinyl terminated polydimethylsiloxane which reduces tackiness and improves the shelf stability. Wettability is improved by including a surfactant resulting in a surface contact angle with water at three minutes of less than 50.degree.. 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 the impression making process.

Abstract: A method of preparing an impression of dentition in the oral cavity is provided that overcomes a problem of transfer of inhibitors left by latex gloves that interfere with platinum catalyzed hydrosilation reactions. The method involves applying a surfactant, preferably with peroxide, to the area that is to have its impression taken substantially immediately before applying the impression taking material, rinsing the composition from the area and proceeding with the taking of the dental impression. Preferably the decontaminating composition consists essentially of surfactant, especially polyoxyethylene surfactants, hydrogen peroxide and water.

Abstract: A dental impression package pre-loaded with dental impression material adapted for taking accurate impressions of a patient's teeth and/or gums by professional personnel is provided. The impression material used is flowable to a desired degree and has a viscosity of substantially one million centipoises. Packaging a pre-loaded dental impression tray is accomplished by first quickly immersing the loaded tray in a solution of natural latex for a few seconds and then quickly removing the coated product followed by quickly immersing it in a coagulating solution of acetic acid for a few seconds to stabilize the latex coating; withdrawing the stabilized coated product; drying it; and suitably packaging the product for storage and sale. If the impression material is of a light-curable nature, the packaging is of light-opaque nature.

Abstract: 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.
