摘要： 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, a wobbling technique is used to determine an occlusal position of the lower and upper dental arches.

摘要： An orthodontic appliance (10) such as a bracket has bonding structure (19) that provides a greater bond strength to the tooth in regions beneath an occlusal edge portion (28) of the base (20) in comparison to regions beneath at least one of a mesial edge portion (22) distal edge portion (24) and gingival edge portion (26) of the base. The weaker bond strengths beneath the mesial edge portion (22) the distal edge portion (24) and/or the gingival edge portion (26) facilitate removal of the appliance (10) by the orthodontist when desired. The higher bond strength beneath the occlusal edge portion (28) is sufficient to securely retain the appliance (10) on the tooth and safely resist the forces normally encountered during orthodontic treatment.

摘要： An orthodontic bracket (20) having mesial and distal sections (22, 24) is debonded from a tooth (40) by pivoting the sections toward each other in respective arcs about a central reference axis extending in an occlusal-gingival direction. The mesial and distal sections are discrete and spaced apart from each other, or alternatively integrally joined by a relatively thin web that bends and optionally fractures upon debonding. A metallic archwire slot liner interconnects the mesial and distal sections and enhances sliding mechanics of the bracket. A pliers-like debonding tool includes jaws with stops for limiting the lingual depth of engagement of the jaws with the mesial and distal sides of the bracket, to facilitate pivoting of the mesial and distal sections during debonding.
