摘要： An integrally molded brush. A preferred embodiment of the integrally molded brush includes a) a generally planar hub having an outer periphery, where the hub has a thickness of at least 0.05 inches; and b) a plurality of bristles extending from the outer periphery of the hub, where each of the bristles includes a bristle tip opposite the hub, where the bristle tip has a thickness up to 0.03 inches, and where the molded brush comprises a thermoplastic polymeric material. The present invention also provides a method of molding an integrally molded brush. A preferred embodiment of the method includes the steps of: a) heating a thermoplastic polymer to allow the thermoplastic polymer to be injected into a mold; b) injecting the thermoplastic polymer into a mold, wherein the mold includes a hub section and a plurality of bristle sections in fluid communication with the hub section, where the bristle tip section has a thickness up to 0.03 inches; c) injecting the thermoplastic polymer into the hub section of the mold, while maintaining the thermoplastic polymer at a high enough temperature to prevent solidification of the thermoplastic polymer; d) injecting the thermoplastic polymer into the plurality of bristle sections of the mold so as to substantially fill the plurality of bristle sections with the thermoplastic polymer; e) sufficiently cooling the thermoplastic; and f) thereafter removing the integrally molded brush from the mold.

摘要： A dental brush has a plurality of bristles and is adapted to connect to a dental handpiece. As the brush is rotated, outer portions of the bristles shift and present an overall tapered configuration with a narrowed outer tip when the bristles come into contact with dental structure. The tapered configuration is particularly useful for finishing and polishing recesses in the patient's tooth structure such as interproximal areas, grooves located next to cusps of the teeth and recesses that may be present in dental restorations.
