摘要
目的:探讨锥束CT(Cone Beam Computer Tomography,CBCT)评估上颌后牙区牙槽骨高度准确程度,评价其指导闭合式上颌窦内提升术的临床效果。方法:对55例计划行上颌后牙区种植患者拍摄CBCT,根据分析结果将适合行上颌窦内提升术患者纳入研究人群,治疗结束后评估其临床效果。结果:CBCT上颌后牙区牙槽骨骨量不足者检出45例,1例上颌窦根尖囊肿,2例窦底粘膜过度增生,其中4例窦底距离牙槽嵴顶骨高度小于4mm者建议使用上颌窦侧壁开窗上颌窦底提升植骨手术,38例完成闭合式上颌窦内提升并全部完成修复,成功率为100%。结论:CBCT在上颌后牙区颌骨骨量判断及术前指导有着重要作用。
Objective To Explore the accuracy of posterior maxillary bone height by CBCT and assess the clinical results after a modified osteotome technique to lift sinus floor without grafting materials.Methods 55 cases with tooth lost in maxillary posterior were taken CBCT;the objects that would be taken sinus floor elevation using osteotome technique without grafting materials were decided by the analysis of bone height results,then to evaluate the clinical results after the restoration of the tooth.Results 45 cases were detected with a lacking of maxillary posterior alveolar bone height,and 1 case was diagnosed as maxillary radicular cyst,2 cases were found as sinus mucosal hyperplasia,and 4 cases whose sinus alveolar bone height were less than 4mm recommended the using of maxillary sinus wall of windows surgery,38 patients completed the sinus floor elevation using Osteotome Technique and finished the restorations at last.The success rate was 100% within one year.Conclusion CBCT has an important role in determining the quality of the bone in maxillary posterior and in preoperative guidance before the implant operation.
