Abstract:
With the wide application of digital technology in the field of stomatology, the acquisition of three-dimensional tooth and dentition information through three-dimensional (3D) image data and optical scan data has become an indispensable process in clinical diagnosis and analysis. Cone-beam CT images and optical scanning images have their own characteristics in terms of data acquisition range and the accuracy of data. Single data source is not accurate enough or complete in the delivery of tooth and dental information. At present, two data sources are used to construct a 3D crown root model with high-precision crown and complete root information to meet the requirement of clinical orthodontic functional setup and implant surgical guide design. The integration of tooth crown and root is one of the focused topics of clinical research. This review will summarize the research progress of 3D crown root model construction method, introduce the application of various algorithms, and analyze the characteristics of these approaches, in order to provide reference for clinical application and scientific research.
