Manipulating a digital dentition model to form models of individual dentition components
Granted: August 1, 2002
Application Number:
20020102009
A programmed computer is used to create a digital model of an individual component of a patient's dentition. The computer obtains a 3D digital model of the patient's dentition, identifies points in the dentition model that lie on an inter-proximal margin between adjacent teeth in the patient's dentition, and uses the identified points to create a cutting surface that separates portions of the dentition model representing the adjacent teeth.
Manipulable dental model system for fabrication of a dental appliance
Granted: July 18, 2002
Application Number:
20020094503
The present invention provides a manipulable or reconfigurable dental model system and methods for its use to model a series of tooth configurations corresponding to sequential tooth movements during an orthodontic treatment. When a patient undergoes orthodontic treatment, teeth and bite configurations are realigned in a series of stages. Each stage represents a new pattern or dental configuration that will eventually lead to a proper final positioning of the entire dentition. Progress…
