Abstract: A method for generating a virtual jaw image includes performing a movement recording method to obtain a movement record which comprises producing at least one position data record over a defined time. A position data record describes a spatial position of a lower jaw to an upper jaw at a specific time. Surface sections of the upper and lower jaw are scanned at the defined time during the movement recording method to obtain a spatial relation of the surface sections during the defined time. Digital upper and lower jaw images are recorded. A position data record of a virtual position of the digital lower jaw image is assigned to the digital upper jaw image. A position data record is selected to obtain a selected position data record. The digital lower and upper jaw images are virtually aligned based on the selected position data record to produce the virtual jaw image.

Abstract: The cheek pouch anchor, formed of a resilient filament, fits within a user's cheek pouch. The anchor dynamically spans a user's inter-occlusal space and lip opening as a user's jaws open and close. The anchor can be formed of inter-connected, conversely-adjustable loops to enable user adjustment of its span. It can stabilize a work piece, such as an airway, in a user's mouth. The cheek path airway fits a path between a user's lips and through the user's cheek pouch and rear-jaw gap, avoiding the user's bite. It provides supplemental air to a user's rear-mouth cavity independently of a user's nasal airways while a user's lips remain closed. It can be used in combination with mandibular jaw-control and tongue-control devices whereby the combination mitigates breathing restrictions in a user's nasal and throat airways. It can be manufactured in-line and folded by a user to fit the user's cheek pathway.
