The apparatuses can comprise arch-shaped elements with any of several features that allow ease of use, ease of customization to individual users, and implementation of airways desirable for applications such as airway management. ## Claims ### Claim 1 An airway management device, comprising a material compatible with a human mouth shaped to conform to the arch of a user's teeth and to at least one of the user's upper or lower teeth, and having one or more air passages extending from a lingual side of the device when held between the user's teeth to the buccal side. ### Claim 2 (depends on 1) An airway management device as in claim 1, wherein the material comprises silicone. ### Claim 3 (depends on 1) An airway management device as in claim 1, wherein the device has a cross-section that is U-shaped, with at least a portion of the interior of the U-shaped cross-section conforming to at least a portion of the user's upper or lower teeth. ### Claim 4 (depends on 1) An airway management device as in claim 1, wherein the device has a cross-section that is H-shaped, with at least a portion of the interior of an upper portion of the H-shaped cross-section conforming to at least a portion of the user's upper teeth, and at least a portion of the interior of a lower portion of the H-shaped cross-section conforming to at least a portion of the user's lower teeth. ### Claim 5 (depends on 1) An airway management device as in claim 1, wherein an air passage is configured to connect with a CPAP machine. ### Claim 6 (depends on 15) A method of producing an airway management device as in claim 15, comprising: (a) providing a tray configured to match an arch of a user's teeth, where the tray has a lingual face and a buccal face that together define an internal channel shaped to accommodate at least a portion of the user's upper teeth, lower teeth, or both; and wherein the tray defines one or more airway channels extending from the lingual face to the buccal face; (b) applying settable material to the internal channel but not in the one or more airway channels; (c) causing the user to bite on the tray, forcing one or more of the user's teeth into the internal channel and encouraging the settable material to conform to the shape of the one or more of the user's teeth; (d) waiting for the settable material to set. ### Claim 7 (depends on 15) A method of producing an airway management device as in claim 15, comprising: (a) providing a buccal shield configured to match an arch of a user's teeth, and wherein the buccal shield has one or more protrusions extending from the concave side of the shield a first distance; (b) applying an amount of a settable material to the concave side of the shield, surrounding the one or more protrusions, and extending less than the first distance from the concave side of the shield; (c) placing the buccal shield such that the settable material is between the user's teeth, and causing the user to bite on the settable material, forcing one or more of the user's teeth into the settable material and encouraging the settable material to conform to the shape of the one or more of the user's teeth; (d) waiting for the settable material to set; (e) removing the buccal shield and the one or more protrusions from the settable material. ### Claim 8 A dental tray for forming dental appliances, comprising an arch element defining an arch that matches an arch of a user's teeth and having a H-shaped cross-section; wherein the arch element defines one or more air passages extending from the concave side of the arch to the convex side of the arch separated from the internal channels formed by the H-shaped cross-section. ### Claim 9 (depends on 8) A tray as in claim 8, wherein the arch element comprises a flexible element and a bendable element that retains its shape once bent, mounted together such that the flexible element takes a shape defined by the shape to which the bendable element is bent. ### Claim 10 (depends on 9) A tray as in claim 9, wherein the bendable element is mounted in a removeable relationship with the flexible element. ### Claim 11 (depends on 9) A tray as in claim 9, wherein the arch element defines one or more retention channels through the middle bar of the H-shaped cross-section connecting the internal channels formed by the H-shaped cross-section. ### Claim 12 (depends on 9) A tray as in claim 9, wherein the arch element comprises a lingual flange, a buccal flange, and one or more connectors configured to mount with the lingual flange and the buccal flange and constrain the lingual flange and buccal flange to a shape that accommodates at least a portion of a user's upper or lower teeth between the lingual flange and the buccal flange. ### Claim 13 (depends on 13) A tray as in claim 13, wherein the one or more connectors are configured to snap into openings in the lingual flange and in the buccal flange. ### Claim 14 (depends on 9) A tray as in claim 9, further comprising a quantity of settable material suitable for application into the tray and conformance with one or more teeth of a user after setting. ### Claim 15 A method of producing an airway management device, comprising providing a form that assists a settable material in conforming to at least a portion of a user's teeth, wherein the form includes one or more elements that provide airways through the settable material.
