Abstract: Embodiments of the present invention relate to an oral hygiene device for use in cleaning the teeth as well as the interproximal spaces between the teeth, and methods of manufacturing and using same. In accordance with one embodiment of the present invention, an oral hygiene device comprises a substantially rigid member having a dental cleaner on a first end and an interdental cleaner substantially terminating in an apex on a second end, the substantially rigid member being substantially free of filaments and bristles, and a coating material disposed on an outer surface of the dental cleaner, the coating material comprising at least an abradant.

Abstract: An interocclusal appliance includes a maxillary impression preform of a resilient thermoplastic having a low softening temperature, e.g. 36° C., such as an EVA copolymer having approximately thirty percent vinyl acetate. The preform is molded over and unitarily bonded to a base having a planar bottom face contacted by mandibular occlusal surfaces. The base is formed of a thermoplastic having a higher softening temperature, e.g. 70° C., with the bond between the preform and base characterized by high shear strength. The preform includes a bight shaped centric relation positioning channel having a thick footing and draft along lingual, buccal and labial walls. The appliance is fitted by immersion in hot water to soften the preform, seating the maxillary arch within the channel and biting, such that the impression of the maxillary dentition embeds in the softened preform. Upon cooling, the preform is transformed into a reusable resilient encasement for the maxillary dentition.
