Abstract: Methods and systems are described to digitally model the 4-dimensional dynamics of jaw and tooth motion using time-based 3-dimensional data. Complete upper and lower digital models are registered to time-based 3-dimensional intra-oral data to produce a true 4-dimensional model. Diagnostic and clinical applications include balancing the occlusion and characterizing the geometry of the temporomandibular joint. The 4-dimensional model is readily combined with conventional imaging methods such as CT to create a more complete virtual patient model.

Abstract: A digitally-based method is described for the design and production of customized removable dental appliances. The plastic component of custom appliances is designed using software, and milled directly over a plaster model of the dentition. A patient's upper, lower, and bite-registered arches are digitized, registered to a bite or centric occlusion position, and articulated in software using either an average geometry or the geometry of a specific articulator. Appliance design is performed by defining the desired plastic surfaces and margins as dictated by the relative movement and positions of the arches as functionally required for a specific appliance. Standard CAM software is used to read the design file and command a multiaxis machine center to mill the plastic while directly on a plaster model.
