摘要：
A method or computer program for forming a digital model of a patient's teeth. The method includes the steps of: obtaining a plurality of projection images acquired by scanning a negative impression of the patient's teeth using a computed tomographic imaging apparatus； generating, from the plurality of projection images, an air volume model of the air that surrounds the negative impression； defining a transition surface along edges of the air volume model that touch the negative impression； forming the digital model of the patient's teeth according to the defined transition surface； and displaying, storing, or transmitting at least a portion of the digital model of the teeth.
