    摘要： The present invention relates generally to methods for making dental appliances and prostheses, particularly dentures. A polymerizable dental composition is used in the method. The polymerizable dental composition comprises a polymerizable acrylic compound; a polymerization initiation system, capable of being activated by light or heat, for polymerizing the composition; and a solvent capable of at least partially solubilizing wax material. Preferably, a mixture of heptane and methyl acetate solvents is used. The compositions are able to remove wax residue effectively and improve the bonding strength of a denture baseplate to subsequently applied materials.

    摘要： A dental handpiece includes a body having a first portion and a second portion, the first and second portions disposed at an ergonomic angle to each other. A drive gear extends from the second portion toward the first portion. The drive gear has a first axis of rotation and rotatably drives at least one driven gear having a second axis of rotation. The at least one driven gear is operatively connected to a bur disposed in the first portion to rotatably drive the bur about a third axis of rotation. The drive gear and the at least one driven gear do not include a taper gear or a face gear.

    摘要： A method of applying a dental composition to tooth surfaces is provided. The dental composition, comprising polymerizable resin and fluorescing compound, is applied to a tooth surface and cured so that it hardens. The composition is preferably used as a dental sealant that provides a hard, glossy surface finish over a tooth. Upon irradiating the sealant with ultraviolet light, the sealant exhibits a bright fluorescent glow. The sealant reverts immediately to its natural color when it is no longer exposed to the ultraviolet light.

    摘要： A multi-component, mixing storage and dispensing package (10) has a housing (11), a displaceable cavity block (20) having at least one cavity (21) therein. A vent spike block (40) having at least one spike (42) held in an opposing relation to at least one cavity (21) is provided within the housing (11). When cavity block (21) is caused to move toward the vent spike block (40) spike (42) is caused to enter a cavity (21). A vent (43) is in fluid communication through the spike (42) with a mix channel (51) and a mixing and dispensing tip (50).
