摘要
Abstract
Objective:Cone-beam computed tomography (CBCT) was used to analyze and assess anatomical varia-tions and morphology features of nasopalatine canal. It provided valuable information for dental implant surgery of anterior maxilla regions,as well as diagnosis of nasopalatine canal cyst. Method:Two hundred and eighty-nine CBCT images were randomly selected from the database of the department of oral radiology,West China Hospital of Stomatology. All the CBCT images were carefully analyzed and classified. Result:The most prevalent type on sagittal images was cylindrical shape (103,35.64%);on axial images,none bony crest was the most prevalent among incisive foramen(154,53.29%) and middle foramen (138,47.75 %);bony crest (160,55.36 %) was the most prevalent in nasopalatine foramina;single canal (204,70.59%) was the most common in coronal images. Conclusion:Nasopalatine canal shows highly anatomical variations. A clearly analysis with CBCT before surgery in anterior maxilla region is helpful in providing necessary information for den-tal implant surgery. It helps doctors avoid damaging nerves and vessels in nasopalatine during the surgery.关键词
