基于CBCT的上颌窦外侧壁血管解剖特点及在种植术中的应用分析
Analysis on CBCT in Evaluating the Shape of the Lateral Wall of Maxillary Sinus and Its Clinical Application
摘要
Abstract
Objective Cone-beam computed tomography(CBCT)was used to study the maxillary sinus artery and its related anatomical features at the site of the maxillary first molar.Methods From January 2020 to August 2022,363 patients(including 500 maxillary sinuses,including 181 males and 182 females)with missing maxillary first molar were selected from the image database of Hefei Stomatological Hospital.The diameter of maxillary sinus artery,the thickness of the lateral wall of maxillary sinus corresponding to the artery,the distance L1 from the bottom of maxillary sinus to the top of alveolar ridge,and the diameter of maxillary sinus artery from the lateral wall plane to the bottom of maxillary sinus were measured.Results The average diameter of maxillary sinus artery was(1.14±0.45)mm,and there was no difference between the sexes.The average thickness of lateral wall of maxillary sinus is(1.79±0.45)mm,and the diameter of maxillary sinus artery is related to the thickness of lateral wall of maxillary sinus.The average distance L1 from the base of maxillary sinus to alveolar ridge is(5.30±2.87)mm,and 58.14%of them need maxillary sinus extraction.The average distance L2 from the maxillary sinus artery to the maxillary sinus floor on the lateral wall plane is(8.53±3.08)mm.The lateral wall thickness and L1 of maxillary sinus are different in different sexes.Conclusion CBCT can clearly observe the anatomical characteristics related to implantation,such as the location of maxillary sinus artery,and can directly measure related indexes.Its three-dimensional image can provide preoperative guidance for clinical implantation surgery and evaluate related surgical risks.关键词
