A61L 15/28
US Classification:
604368, 604378, 604369, 604372, 604374
Abstract:
A fluid management cover system of launderable and durable character including at least one fluid transport layer with at least one absorptive reservoir layer disposed in underlying relation to the fluid transport layer. The upper surface of the absorptive reservoir layer is characterized by a greater capillarity than the adjacent surface of the fluid transport layer such that fluid is drawn away from the fluid transport layer and is held within the absorptive reservoir layer. At least one pressure distribution layer incorporating material that at least partially recovers following compression is disposed at a position below the absorptive reservoir layer. An optional skin contacting layer may be disposed above the fluid transport layer and an optional backing layer may be disposed in underlying relation to other layers.

Abstract:
The example systems, methods, and/or computer-readable media described herein help with design of highly accurate models of un-erupted or partially erupted teeth and help fabricate of aligners for un-erupted or partially erupted teeth. Automated agents that use machine learning models to parametrically represent three-dimensional (3d) virtual representations of teeth as 3D descriptors in a 3D descriptor space are provided herein. In some implementations, the automated agents described herein provide instructions to fabricate aligners for at least partially un-erupted teeth using representative 3D descriptor(s) of a tooth type.

A61C 7/08
Abstract:
A series of appliances including a first shell and a second shell can be designed to incrementally implement a treatment plan. The first and second shells can have cavities designed to receive teeth of a jaw. A first number of bite adjustment structures can be formed of a same material as the first shell, extending therefrom and designed to interface with teeth of a second jaw. The first number of bite adjustment structures can have a first shape and location specific to a first stage of the treatment plan. A second number of bite adjustment structures can be formed of a same material as the second shell, extending therefrom and designed to interface with teeth of the second jaw. The second number of bite adjustment structures can have a second shape and location, different than the first shape and location, specific to a second stage of the treatment plan.
