摘要： 目的：探讨利用锥形束CT(cone beam computer tomography,CBCT)评估上颌后份缺牙区牙槽骨的骨量情况,评价其指导上颌窦提升术的临床效果。方法：对28例计划行上颌后牙区种植患者拍摄CBCT,根据分析结果,上颌窦底骨高度5~10 mm、适合行经牙槽嵴顶上颌窦提升术患者19例,上颌窦底骨高度<5 mm、适合行经侧壁开窗上颌窦提升术患者7例,治疗结束后评估其临床效果。结果：CBCT检测上颌后牙区牙槽骨骨量不足者26例,l例上颌窦黏液囊肿,2例上颌窦分隔。19例完成经牙槽嵴顶上颌窦提升术,7例完成经侧壁开窗上颌窦提升术,并全部完成修复,成功率为1 00%。结论：CBCT在上颌后牙区颌骨骨量判断及上颌窦底提升术中具有重要指导作用。

Abstract: PURPOSE: To investigate the value of using con-beam computer tomography (CBCT) to evaluate bone volume in the edentulous area of posterior maxilla, and guide sinus floor elevation. METHODS: Twenty eight patients who planed to receive dental implant in the posterior maxilla underwent CBCT scan. After analysis of residual bone height, 19 patients with 5-10 mm bone height below the sinus floor underwent transcrestal sinus floor elevation, while 7 patients with less than 5 mm bone height below the sinus floor underwent lateral window sinus floor elevation. The treatment outcomes were assessed postoperatively. RESULTS: CBCT detected bone deficiency in the posterior maxillary alveolar bone in 26 patients, mucus cyst of maxillary sinus in 1 patient and sinus septa in 2 patients. Nineteen patients underwent transcrestal sinus floor elevation, and 7 patients underwent lateral window sinus floor elevation. All patients completed final dental restorations, and the restorations achieved satisfactory function and esthetic. CONCLUSIONS: CBCT imaging plays an important role in determining bone quality in posterior maxilla and guiding sinus floor elevation.
