Abstract
Objective:To study the three dimensional rebuilding method of fixed bridge based on the digital images by spiral CT. Method:By the PQ6000 spiral CT,successive cross-sectional scanning was made from the inferior edge of the mandibular chin to the bottom of the nasal bone to obtain the two-dimensional digital images. Using the image processing and recognition software,two-dimensional CT image data file was established. Two-dimensional gray image segmentation method was adopted for edge detection. Further,three-dimensional surface reconstruction algorithm was used for the three-dimensional reconstruction of the fixed bridge by intercepted two-dimensional image. Result:Three-dimensional image of fixed bridge,including abutment teeth,periodontal membrane and alveolar bone,was obtained,which was rather vivid in every detail,and could be rotated,dissected,perspected,and intercepted optionally. It made the observation of images from different angles as possible. The reconstruction showed satisfactory replicating effects. Conclusion:Three-dimensional reconstruction of the fixed bridge by digital scanning of spiral CT could provide us a convenient and fast method for finite element model establishment.关键词
