摘要:
A method of obtaining and merging volumetric data and surface data of a patient's dentition for use in designing and/or manufacturing a prosthodontic component, such as a drill guide, an implant, or other prosthodontic appliance, for example. A plurality of radio-opaque markers are temporarily secured directly to a patient's dentition. Surface data is then obtained, such as by scanning the patient's dentition with the markers or alternatively, by taking an impression of the patient's dentition with the markers, forming a physical model that includes analogs of the markers, and scanning the physical model. Either before or after the surface data is obtained, an anatomical, volumetric image data set of the patient's dentition is obtained via a volumetric scan of the patient's dentition with the markers appearing in the image data set. The markers appearing in both the volumetric data set and the surface data set are used by suitable computer software to merge the volumetric and surface data sets to form a merged image data set and to generate a combined model of the patient's dentition from which a surgical drill guide or other prosthodontic appliance may be designed and manufactured.
