Dental　panoramic　radiography,　which　plays　an　important　part　in　the　diagnosis　of　oral　diseases　especially　the　plastic,　has　been　widely　used　in　hospitals　as　a　branch　of　radiography.　The　dental　panoramic　X-ray　images　show　a　two-dimensional　view　of　whole　teeth　from　left　second　molar　to　right　second　molar　only,　but　they　do　not　contain　the　3D　information　of　patients＇　oral　and　maxillofacial　anatomical　structure.　A　method　was　proposed　in　this　paper　to　bend　the　dental　panoramic　X-ray　images　according　to　the　curve　which　was　fitted　by　the　patient-specific　dental　arch　for　the　3D　visualization　of　dental　panoramic　X-ray　images.　©2009　IEEE.
