DEVICE AND METHOD FOR REGISTERING 3D MEASUREMENT DATA OF JAW MODELS IN A BASAL SKULL-REFERENCED COORDINATE SYSTEM WITH THE AID OF A COMPUTER-SUPPORTED REGISTRATION SYSTEM

摘要

An apparatus and method for use in the field of orthodontia and dental prosthodontics for registering 3D measurement data of a jaw model having a lower jaw model and an upper jaw model in a cranial-referenced coordinate system. The method and apparatus establish a spatial relationship between a cranium and the measurement data of the jaw models obtained from optical scanners. This is implemented by determining the spatial relationship between a paraocclusal spoon or a bite fork and jaw joints using a computer aided registering system, and by determining the spatial relationship between the paraocclusal spoon or the bite fork and the jaw model which provides locatable structures whose spatial relationship to the paraocclusal spoon or the bite fork is known.
