Abstract: The present invention relates to skin care compositions with improved aesthetic and physical characteristics comprising a lotion, cream or anhydrous base and talc with specific ratios of the non-volatile ingredients to talc.

Abstract: A stain resistant no-mix orthodontic adhesive is disclosed. The adhesive comprises:(a) a first component having a relatively low viscosity and which contains an acrylic or methacrylic diester of ethoxylated bisphenol-A, an acrylic or methacrylic diester of an alkanediol, and benzyl acrylate or methacrylate; and(b) a second component containing a filler and an acrylic or methacrylic diester of ethoxylated bisphenol-A, an acrylic or methacrylic diester of an alkanediol, and benzyl methacrylate or acrylate, said filler being present in an amount within the range of from about 50 to about 80 weight percent of said second component,wherein, one of said first and second components contains a perioxide catalyst and the other of said components contains a tertiary amine activator for said peroxide catalyst.

Abstract: Orthodontic brackets are made from ion exchange strengthened glass. In a preferred embodiment, the glass is a lithium alumino silicate srengthened with sodium ions.

Abstract: A filler for use in dental composites is made by the following process:(a) finely divided silica, such as fumed silica, is coated with a polymerizable monomeric material by (e.g., an acrylic monomer) by mixing the silica with an organic solvent solution of the monomer;(b) the solvent is removed by evaporation by any convenient means;(c) the coated silica particles are individualized, as by screening, to produce a powder of a predetermined particle size (e.g., 90 microns or smaller); and(d) the resin is then polymerized.Some individualization of the product of step (d) may be required. Light screening is usually sufficient.

Abstract: A shield for use with a pair of orthodontic pliers in removing an orthodontic bracket. The shield fits snuggly onto one jaw of the pliers and provides side walls adjacent the plier jaws. The jaws have a recess near their distal end such that the confronting surfaces of the jaw recesses and the confronting surfaces of the side walls provide an enclosure about a bracket while it is being removed so that if it fractures the enclosure will contain any pieces that may break off the bracket.

Abstract: A cruciate ligament prosthesis constructed with two separately tensionable strands. Each strand is composed of a plurality of fine polyolefin filaments, each filament having a diameter of from 25 to 50 microns and the breaking strength of each strand is at least 1000 pounds.
