Title:
IMAGE GUIDED IMPLANTOLOGY METHODS
Document Type and Number:
WIPO Patent Application WO2002096261
Kind Code:
A3
Abstract:
A method for correcting inherent distortions in a CT or MRI imaging process (50), or distortions arising from excessive patient movement during the scan by means of registration device inserted into the mouth (40) of the patient at the time the scan is being performed. The registration device incorporates a set of fiducial markers disposed in a predetermined three-dimensional pattern. The exact positions of the fiducial markers are known with respect to each other, thus providing a three-dimensional references against which the resulting images can be compared (48). Additionally, a method whereby three-dimensional CT or MRI images taken prior to an operation, are accurately registered and integrated with real-time tracking positional data of the patient's body part and instruments operating thereon. Application is described for the drilling of a patient's jaw for the placement of dental implants.
