Abstract: A therapeutic position verifying tool is a semi-custom oral appliance equipped with adjustment assemblies for setting trial occlusion dimensions during a process of fitting a patient for an oral appliance. The oral appliance is fabricated from a polymer such as control-cured PMMA. The adjustment assemblies enable the vertical, anterior-posterior and lateral occlusion dimensions to be set. Occlusion dimensions are measured directly with a pharyngometer or indirectly with a bite registration method. The measurements are transferred to the tool by setting the tool to the measured dimensions using the adjustment assembly. When a target therapeutic position for a patient is found, the patient tests the position during the night with a Polysomnogram (PSG) or Home Sleep Test (HST). The use of the tool in verifying a therapeutic position for an oral appliance eliminates much of the time-consuming process of titrating the appliance to the patient.

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.

Abstract: A dental device has a U-shaped carrier with at least one channel for embracing an arch of teeth. There are recessed insets in the channel. Discrete inserts carrying a beneficial agent can fit into the insets and release the agent gradually. The device may be used in a therapeutic application and as an athletic mouthguard. Temporary blanks may be initially fitted in the insets, while a portion of the mouthguard is softened before an arch of teeth is pressed into the channel to make a custom impression. The inserts possess different physical properties than the carrier and may be positioned and shaped to mechanically buffer teeth of the arch from mechanical shocks as well as release beneficial agents. The inserts may be replaced or refreshed to maintain the beneficial agent. A dental device having a core carrying a beneficial agent inside a liquid-permeable shell functions as an infant's teething device.
