  • Patent number: 9010334
    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.

  • Patent number: 8622738
    Abstract: An orthodontic brace system includes brackets having a diamond-shaped tie-wing configuration that defines two parallel, horizontal slots, each of which is adapted to receive an archwire. Each slot is angled with respect to the base of the bracket to produce a specific, maximum torque value, and generally, the maximum torque value of the gingival slot is less than the maximum torque value of the incisal slot. The brackets provide multiple force vectors in different directions simultaneously, which decreases the amount of time required for a patient to wear braces, reduces the number of costly and time consuming visits to an orthodontist, and reduces time and effort required of an orthodontist for installation and adjustment of the braces on a per visit basis. A self-ligating bracket with a sliding door is disclosed in another embodiment.

  • Patent number: 8485816
    Abstract: An orthodontic bracket is disclosed having three archwire retention channels in the mesial-distal directions, a central channel and two side channels. The two side channels each include a pair of spaced apart inverted archwire retaining regions having a recess that opens generally towards the bracket base. Each such recess is for grasping or holding an archwire therein. Each of the side channels has an archwire retaining ridge extending gingivally-occlusally along the adjacent side of the bracket base between the two retaining regions of the channel. For each channel, its retaining ridge exerts a force on a portion of an archwire facing away from the archwire portion residing in the recesses of the retaining regions of the channel. The force on the archwire is directed toward the interiors of the recesses of the retaining regions for assisting in seating the archwire in the recesses.

  • Patent number: 8464709
    Abstract: The cheek pocket 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, adjustable loops to enable user adjustment of its whole 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.
