In some examples, the piezoelectric sensor can be configured to measure movement of the upper jaw during chewing. [0079] In other configurations, a removable oral device comprises a palatal element coupled to a clasping element and an accelerometer. For example, the accelerometer can be within the body of the palatal element. The accelerometer can be used for many different uses, e.g., the accelerometer can be configured to measure impact force.

[0080] In some embodiments, a removable oral device comprises a palatal element coupled to a clasping element and an electrode. For example, the electrode can within the body of the palatal element and may be configured, for example, to measure bioelectrical impedance to determine a body fat percentage of the user.

[0081] In other examples, a removable oral device comprising a palatal element and a clasping element is provided. For example, the clasping element may not include any supporting wires or other structures.

[0082] In other embodiments, a removable oral device comprises a palatal element coupled to a clasping element, where the clasping element comprises a continuous wire structure terminating in the body of the palatal element, and wherein the continuous wire structure has a smaller outer wire diameter at termini of the wire structure within the clasping element than an outer wire diameter within the palatal element is described. If desired, a clasping element can be coupled to each side of the palatal element.

[0083] In some examples, wherein the palatal element comprises a lower thickness at a front section adjacent to inner surfaces of the anterior teeth to reduce lisping compared to a thickness at an apex section of the palatal element.

The removable device 210 can be used with case 260, e.g., one which can store, charge and/or transfer information to and/or from the removable oral device 210. The removable oral device 210 can be used with a body composition monitor 270 to measure weight, body fat composition, etc. Other external devices which can be used with the removable oral devices will be readily selected by the person of ordinary skill in the art, given the benefit of this disclosure.

[0088] In certain configurations, the various external devices typically comprise common components such as a processor, one or more memory units and/or an operating system. The external device typically is separate from the removable oral device, but a processor, memory chip or other device may be integrated into some component of the removable oral device as desired. At least one processor can be electrically coupled to one or more memory units to receive input data and/or store any data. The processor may be, for example an Intel PENTIUM- type processor, Motorola PowerPC, Sun UltraSPARC, Hewlett-Packard PA-RISC processors, or any other type of processor. Various aspects of the systems and external device which include an on-board processor may be implemented as specialized software. A processor can be, if desired, connected to one or more memory devices, such as a disk drive, memory, or other device for storing data. Memory is typically used for storing programs and data during use of the removable oral device. Electrical components of the external device and/or the systems described herein may be coupled by an interconnection device, which may include one or more buses (e.g., between components that are integrated within a same component) and/or a network (e.g., between components that reside on separate discrete components). The interconnection device provides for communications (e.g., signals, data, instructions) to be exchanged between components of the system. The processor and other components are electrically coupled to a power source. In addition, the system or external device may comprise one or more interfaces that connect the processor to a separate device or system such as, for example, a communication network (in addition or as an alternative to the interconnection device). Illustrative interfaces include, but are not limited to, a serial ATA interface, ISA interface, PCI interface or the like or one or more wireless interfaces, e.g., a Bluetooth device, a Wi-Fi device, a Near Field Communication device, a cellular device or other wireless protocols and/or interfaces.

[0089] In certain embodiments, the storage system of the external device or the system typically includes a readable and writeable nonvolatile recording medium in which data can be stored. The medium may, for example, be a solid state memory chip, solid state drive or flash memory. Typically, in operation, the processor causes data to be read from the nonvolatile recording medium into another memory that allows for faster access to the information by the processor than does the medium. This memory is typically a volatile, random access memory such as a dynamic random access memory (DRAM) or static memory (SRAM). It may be located in the storage system or in the memory system. The processor generally manipulates the data within the integrated circuit memory and then copies the data to the medium after processing is completed. A variety of mechanisms are known for managing data movement between the medium and the integrated circuit memory element and the technology is not limited thereto. The technology is also not limited to a particular memory system or storage system. In certain embodiments, the system or external device may also include specially-programmed, special- purpose hardware, for example, an application-specific integrated circuit (ASIC) or a field programmable gate array (FPGA). Aspects of the technology may be implemented in software, hardware or firmware, or any combination thereof. The external device or system may use or include a high-level computer programming language or specially programmed, special purpose hardware.

[0090] In certain examples, the processor and any associated sensors or components of the external device or the system may together define a computer platform for which application programs in high-level programming languages may be written. It should be understood that the technology is not limited to a particular computer system platform, processor, operating system, or network. Also, it should be apparent to those skilled in the art, given the benefit of this disclosure, that the present technology is not limited to a specific programming language or computer system. Further, it should be appreciated that other appropriate programming languages and other appropriate electrical components could also be used. In certain examples, the hardware or software can be configured to implement cognitive architecture, neural networks or other suitable implementations. In some instances, various configurations may be programmed using an object-oriented programming language, such as SmallTalk, Basic, Java, C++, Ada, or C# (C-Sharp). Other obj ect-oriented programming languages may also be used. Alternatively, functional, scripting, and/or logical programming languages may be used. Various configurations may be implemented in a non-programmed environment (e.g., documents created in HTML, XML or other format that, when viewed in a window of a browser program, render aspects of a graphical-user interface (GUI) or perform other functions). Certain configurations may be implemented as programmed or non-programmed elements, or any combination thereof.

[0091] In certain embodiments, the external device may be configured as a mobile device, e.g., a phone or a tablet, that is configured to control use of (or monitor use of) the removable oral device. The mobile device may wirelessly communicate with the removable oral device to send signals and receive signals or data from the removable oral device or can communicate with the removable oral device in a hard-wired manner.

In other configurations, the printed removable oral device comprises a variable hardness across the tongue surface of the body.

[00135] In certain examples, the exact nature and type of three-dimensional printing used to produce the components of the removable oral device may vary. Illustrative three- dimensional printing technologies include, but are not limited to, selective laser sintering (SLS), fused deposition molding (FDM), laminate object manufacturing (LOM), rapid prototyping, and three-dimensional inkjet printing. Three-dimensional printing methods using digital light processing (DLP) or an injection through a series of tiny nozzles or a single nozzle may use photo-curable materials which can be cured by UV/Vis light. These two methods are rapid, low cost, high resolution, and east to use. Three-dimensional articles can be produced using ink-jet printing techniques that can use several different materials, e.g., from different reservoirs or cartridge, to provide a photo-curable liquid compositions which can be cured by exposure to UV/Vis light. The photo-curable "ink" in the ink-jet printing process is provided through one or more nozzles on a support stage with a pattern defined by a computer aided design file or other three-dimensional coordinates. In one exemplary illustration, successive layers of the palatal element can be "built up" by placing individual layers on the printer support and curing, at least to some degree, the printed layer prior to addition of successive layers. Layers can be added in individual areas until a desired final shape is reached. The final three-dimensionally printed removable oral device can then be washed or treated with one or more other materials if desired. In a three-dimensional printing technique using digital light processing, the photo-curable liquid can be placed in a reservoir. Exposure of certain areas to the curing light can provide layers which can be used to build up the removable oral device. Once a layer has been cured by UV/Vis light, a building platform moves in the z-direction depending on the thickness of the layer. This process is repeated until all layers are formed and/or a desired shape is formed. Illustrative three-dimensional printers include, but are not limited to, those commercially available from Objet or Master supplied by Carima and The Form 1 supplied by Formlabs.

[00136] In some examples, the materials used by the three-dimensional printer may be photo-curable, heat curable, UV curable or cured by adding one or more external curing agents to the printed palatal element to harden the materials.

[00137] In certain examples, the clasping element of the removable oral device may also be printed or the palatal element can be printed with the clasping element or elements present on the printer support. For example, a clasping element in the form of a metal wire can be present on the printer stage, and the palatal element can be printed onto the clasping element to provide the removable oral device with an embedded wire as a clasping element.

[00138] In some examples, the printed palatal element can be heat cured by placing it in an oven to harden the body of the palatal element. If desired, heat tape or other materials can be placed at the edges of the palatal element to prevent hardening of these areas to the same degree as an apex portion of the body. In other examples, one or more curing agent can be deposited onto the entire body of the palatal element or just at apex areas to provide softer edges when the palatal element is cured.

[00139] In certain examples, one or more photo-curing agents can be added to the printed palatal element (or clasping element or both) or may be present in the "ink" used to print the palatal element.
