Abstract:
Methods and apparatus for visualizing and manipulating three-dimensional digital dental models and related methods and apparatus for dental treatments are disclosed. In one aspect, a method for visualizing and manipulating a three-dimensional digital dental model may comprise viewing the three-dimensional digital dental model and using hand gestures to instruct a computer to manipulate one or more teeth in the digital dental model. In other aspects, a dental treatment method may comprise viewing a three-dimensional digital model, using hand gestures, a conventional keyboard, and/or a conventional mouse to instruct a computer to manipulate one or more teeth in the digital model to generate a three-dimensional digital model of a modified arrangement of the subject's teeth, and fabricating one or more dental aligners configured to reposition the subject's teeth into the modified arrangement. Viewing may comprise stereoscopically viewing a digital dental model.
