20090321037 | MOLD ASSEMBLY APPARATUS AND METHOD FOR MOLDING METAL ARTICLES - Apparatus assemblies and methods for melting and injection molding an article from a meltable metal that is sensitive to heating by radio frequency (RF) induction. An exemplary apparatus includes a mold including a cavity having a shape of an article to be molded, a delivery chute including a channel for delivering a solid metal billet from a proximal end of the delivery chute to a distal end which is adjacent to the mold, and an RF induction heating coil that surrounds the cavity of the mold and the distal end of the delivery chute. Advantageously, the portion of the mold defining the cavity and at least the distal end of the delivery chute (i.e., those portions surrounded by the RF coil) are formed of materials that are substantially insensitive to heating by RF induction so that the metal billet is melted and molded at approximately the same time. | 12-31-2009 |
20090325118 | ORTHODONTIC BRACKETS HAVING A BENDABLE OR FLEXIBLE MEMBER FORMED FROM AMORPHOUS METALLIC ALLOYS - Orthodontic brackets having a bracket base including at least one arch wire slot formed therein and a bendable or flexible member (e.g., a film hinge) having a relatively thin cross-sectional thickness to facilitate flexing or bending of the member with little or no permanent deformation, wherein at least the bendable or flexible member comprises an amorphous metallic alloy. | 12-31-2009 |
20100028829 | CHEMICALLY ACTIVATED DENTAL BLEACHING TRAYS - Dental treatment trays and strips used to deliver a dental bleaching composition to a person's teeth are formed from a moisture resistant barrier material and include a bleaching agent destabilizer disposed on an inner treatment surface of the barrier layer that is positioned against the person's teeth during use. The bleaching agent destabilizer may be compounded with the moisture resistant material or otherwise disposed relative to the barrier layer so that at least some destabilizer is positioned on the inner treatment surface of the tray or strip so as to contact the dental bleaching composition during use. | 02-04-2010 |
20110171606 | DENTAL TREATMENT DEVICES - Dental treatment trays or strips include a moisture-resistant barrier layer that is flexible so as to conform to a plurality of differently-sized and shaped dental arches during use. The moisture-resistant barrier layer comprised of wax, paraffin wax and/or polyolefin. The dental treatment device also includes a substantially solid dental treatment composition adapted so as to be initially substantially dry to the touch and so as to become sticky and adhesive to dental tissue when moistened. The substantially solid dental treatment composition includes at least one adhesive agent and at least one active agent, such as a dental bleaching agent. | 07-14-2011 |

20140295377 | DENTAL TREATMENT DEVICES COMPRISING SILICONE-LIKE ELASTOMERIC MATERIAL - Non-customized dental treatment trays used to provide a desired treatment are formed from elastomeric silicone or silicone-like material. They may be molded from a two-part liquid silicone composition or a silicone-like TPE material (e.g., preferably SEBS and/or VERSAflex thermoplastic elastomer). The dental treatment trays possess high adaptability, flexibility, softness, and elastic elongation while also exhibiting resiliency in order to readily conform to the ridges, depressions and contours of a person's teeth during use. The trays possess a greater ability to adhere to a person's teeth compared to non-elastomeric thermoplastic materials. Due to their high adaptability and conformability, the non-customized dental trays behave like a semi-custom dental tray when placed over conformed to a person's teeth, particularly when used in combination with a sticky, viscous treatment composition. | 10-02-2014 |
