Abstract
In an aligning method by grouped data according to the present disclosure, while initial grouped data is generated and a process of generating and aligning three-dimensional image data is performed, if a state in which pieces of three-dimensional volume data are not connected to each other continues for a predetermined time or longer, new grouped data is generated, so that at least one discontinuous grouped data may be generated. If three-dimensional volume data stored in new grouped data and three-dimensional volume data of previously generated grouped data are identified to have overlapping parts therebetween, an additional alignment step is performed to connect the overlapping parts to each other. As a result, a data gap is supplemented, and a patient's entire oral model data can be easily obtained.
