摘要： A type of dental restoration and a method of preparation of dental restorations is disclosed. The dental restoration is provided with an outer shader layer (23), an intermediate at least substantially uncolored, translucent layer (22), and an opaque substructure. The opaque substructure may be a metal support (17) with a surface opaquing agent (21) in one species. The dental restoration may be prepared by removably mounting intermediate uncolored translucent layer that is a crown on an opaque substructure that is a dental mount. The dental mount being matched to an opaque dental cement that will mount the finished shaded dental crown.

摘要： Disclosed is a new urethane polyacrylate having at least one terminal isocyanato acrylic pendent radical. Preferably the molecular chain within the acrylate caps has been extended with a polyhydroxy compound just before final end capping with isocyanato acrylic. The isocyanato acrylic is preferably isocyanato ethyl methacrylate and the urethane is diisocyanate capped polyether and the polyether radical is oxyalkylene. The method for producing the urethane polyacrylate involves end capping a polyol with diisocyanate yielding a reaction product with two reactive equivalents of isocyanate and then capping less than all of the isocyanate with a hydroxyacrylate, after which the remaining isocyanate is reacted with polyol to provide chain extension. The chain extending polyol is then capped with a isocyanato acrylic. Also disclosed is a new impression material for application to mammalian tissue and curing in contact therewith; the impression material including a free radical polymerizable resin, alkyl benzensulfonyl titanate, polymerization initiator, and filler; and a method of use.

摘要： A porcelain paste composition and a method of building a dental appliance are provided. The paste of the invention comprises a mixture of ceramic powders and a curable adhesive resin. In the method, opaqued metal copings are coated with the paste of the invention to provide a coating thereon, and the coating is then cured. The cured coating is prepared by machining or other methods known in the art to obtain the desired shape of the coating and the coping, and the coating is then fired to fuse the ceramic powders in the coating to produce a porcelain finish on the dental appliance.

摘要： An apparatus for measuring the depth of a periodontal pocket comprises a hand held sheath (12) having biasing means (14) and a probe tip assembly (10) associated therewith. The biasing means contacts and biases the probe tip (16) toward one end of the sheath so that the probe tip extends from the sheath. When a measurement is made, the probe tip (10) is pushed into the sheath (12) and the motion of the probe tip is translated through connecting means (14) to a device for measuring the movement of the probe tip. The measuring device is connected with means for automatically recording the measurements obtained. A method is also provided in which possible sites for measurement are preprogrammed, and interactive means are provided which permit the operator to choose the sites for measurement from among the preprogrammed sites in any order. A printout may be provided which correlates the measurements made with parameters identifying the site chosen for measurement.

摘要： Disclosed is a method for producing an intra-oral dental bandage membrane and/or therapeutic membrane containing therapeutic agent. Actinic light is used to polymerize the membrane composition material to fix the composition in position locked with rigid dental structure such as teeth. The polymerizable substance is manipulated and shaped in a fluid state and then set, as shaped very rapidly in situ. Also disclosed is a new treatment membrane that in a preferred form is a non-symetrical oligomer that is a urethane polyacrylate.
