Methods for use in dental articulation

A computer implemented method of creating a dental model for use in dental articulation includes providing a first set of digital data corresponding to an upper arch image of at least a portion of an upper dental arch of a patient, providing a second set of digital data corresponding to a lower arch image of at least a portion of a lower dental arch of the patient, and providing hinge axis data representative of the spatial orientation of at least one of the upper and lower dental arches relative to a condylar axis of the patient. A reference hinge axis is created relative to the upper and lower arch images based on the hinge axis data. Further, the method may include bite alignment data for use in aligning the lower and upper arch images. Yet further, the method may include providing data associated with condyle geometry of the patient, so as to provide limitations on the movement of at least the lower arch image when the arch images are displayed. Further, a wobbling technique may be used to determine an occlusal position of the lower and upper dental arches. Various computer implemented methods of dental articulation are also described. For example, such dental articulation methods may include moving at least one of the upper and lower arch images to simulate relative movement of one of the upper and lower dental arches of the patient, may include displaying another image with the upper and lower dental arches of the dental articulation model, and / or may include playing back recorded motion of a patient's mandible using the dental articulation model.

Anti-obstructive airway dental orthotic

An anti-obstructive airway dental orthotic is described. The orthotic includes a maxillary retainer and a mandibular retainer releasably attaching to a plurality of teeth of a wearer. The retainers are attached by at least one strut, either variable in length or of a plurality of lengths, which exert a forward force on the lower jaw, tending to advance the mandible relative to the maxilla. This advancement of the lower jaw promotes a less obstructed airway in the wearer, while fenestrations in the retainers may allow for greater comfort and tongue movement.
