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： Orthodontic brackets (10) made of a light-transmissive material such as plastic or ceramic have a removable, water-based colorant (32) to facilitate identification of the bracket (10) and alignment of the bracket (10) on the patient's tooth. The colorant (32) is received in a ligature channel (26, 28) of the bracket (10) and is visible through adjacent tiewings (18, 20, 22, 24) of the bracket (10). The colorant (32) is protected by the overlying tiewings (18, 20, 22, 24) from inadvertent damage or removal as might otherwise occur during initial handling and placement of the bracket (10).
