Patent number: 11931220Abstract: Wax-based compositions for making barrier layers used in oral treatment devices are thermally stable when formed into a flat sheet or three-dimensional article to a temperature of at least 45° C. and are plastically deformable at room temperature (25° C.). The wax-based compositions include a wax fraction homogeneously blended with a polymer fraction. The wax fraction includes at least one wax and the polymer fraction includes at least one polymer selected such that, when the at least one wax and at least one polymer are homogeneously blended together, they yield a wax-based composition having the desired properties of thermal stability and plastic deformability. Barrier layers and oral treatment devices made from such wax-based compositions are dimensionally stable to a temperature of at least 40° C. without external support and can be plastically deformed in a user's mouth to become at least partially customized to the size and shape of user's unique dentition.Type: GrantFiled: April 9, 2020Date of Patent: March 19, 2024Assignee: ULTRADENT PRODUCTS, INC.Inventors: Steven B.

Patent number: 9200709Abstract: A mechanical assembly including a pair of members each having a planar surface and a displacing structure can be designed to engage a compressible seal, and thereby reduce or eliminate shear force exerted on the seal, keeping the seal intact during compression. Each displacing structure can have a displacing surface and a latching surface. A compressible seal can be affixed to one of the planar surfaces. Contact between the displacing surfaces during parallel movement of the planar surfaces relative to each other may create a separation between the planar surfaces greater than the compressible seal height. Positioning of the displacing surfaces past each other during parallel movement of the planar surfaces relative to each other may initiate the compression of the compressible seal between the planar surfaces.Type: GrantFiled: May 31, 2013Date of Patent: December 1, 2015Assignee: International Business Machines CorporationInventors: Jessica R.
