A newly developed dental image instrument “The Novel Application to Digital Dental X-Ray by Intraoral Tomosysthesis System” was launched by Dean Lih-Jyh Fuh of CMU College of Dentistry, and the cross-university research and development team he led. This system not only can fulfill the clinical needs of dentists, but also help domestic manufacturers of medical materials to enhance their competitiveness in the international market. The team’s hard work was highly recognized by the committee and was honored by the National Innovation Award.

 

By using this new system, dentists can obtain three-dimensional images (including patients’ teeth, soft tissues, nerves, and alveolar bone) just by a single limited-angle scan. After reconstructing the images from different angles, the system can provide a volume composed by voxels with anatomical structure data. With a special software, the visualization of different cutting planes can be manipulated and be applied to clinical technologies for dental implant, root canal therapy, and dental reconstruction.

 

At the moment, although there are many manufacturers making X-ray devices in the domestic market, only one device has been certified by the Ministry of Health and Welfare. The crucial reason is that digital X-ray sensors cannot be produced domestically, and the resolution of cone-beam computed tomography is not good enough to meet dentists’ requirement. To solve this problem, the team integrated the techniques of dentistry, image reconstruction, sensing technology, and focused on the development of digital X-ray sensors. In addition to improving the technology of domestic manufacturers, its cost advantage also benefits domestic manufacturers in enhancing international competitiveness.
