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 provided and includes a base component and a catalyst component. Both components are siloxane-based materials.

摘要： The invention provides a heat formable tray having a bite block and a method of forming the tray to a patient and forming a final impression in a single visit to the dental office by the patient. A custom fitting variable dimension bite registration dental impression tray, is provided which includes a bite registration member, and a dental impression tray. The dental impression tray comprises a heat adjustable material having a softening point above 38 °C and below 120 °C. The variable dimension bite registration dental impression tray is used in a method for making an impression of dental tissue, comprising the steps of: a) providing a variable dimension bite registration dental impression tray, b) heating the dental impression tray to softened state, c) adjusting the dimensions of the dental impression tray, d) cooling the heat adjustable material so that it solidifies, and e) enveloping the tissue with the dental impression material, whereby a final dental tissue impression is obtained.

摘要： The invention provides dental composition system having curable liquid which is useful alone as a light curable composition and which is useful by mixing with a powder in preselected proportions to form dual cure compositions. The composition system is useful as bonding agent, cement, liner, base, restorative, pit and fissure sealants, and/or core build-up material, having improved adhesion to dentin. After storing the powder and the liquid in separate containers for at least two weeks and then mixing a portion of the powder and a portion of the liquid to form a mixture, the polymerizable compound polymerizes within 20 minutes of the mixing to form a first polymeric material having a flexural strength of at least 50 MPs, and an expansion in water at 37 °C after 90 days of less than 1 percent by volume.

摘要： An ultrasonic dental tooth treatment system including an ultrasonic dental handpiece, a fluid reservoir housing and a power control housing. The reservoir housing is supported by the control housing. The reservoir housing encloses two containers which are connected to the selector valve. The selector valve is connected to a control housing conduit which is connected to the handpiece. The control housing encloses a power control circuit which is connected to the handpiece. In a preferred embodiment of the invention a fluid dispenser includes at least one readily removable reservoir container supported by a reservoir housing having a pivotable cover and a fluid control valve. The cover is pivotable between an open position and a closed position. The valve is closed by the cover when the cover is in its open position.
