Abstract: 3D digital simulation implantation procedure was used in a patient, who had a severely atrophy maxilla with a retention cyst and a septum in the sinus.  Preoperative CBCT examination was used to show the maxillary sinus cyst and the septum. Operation management included maxillary sinus augmentation via a lateral window approach(SLAW) without enucleating the cyst, and a management of sinus membrane perforation with a resorbable collagen membrane. 1 year later, CBCT data showed ideal bone height and a remaining complete cyst, and then the implantation surgery and fixed prosthesis were performed. 1-year-post-prothesis, CBCT showed stable bone height and implants stability, and good occlusion.

Key words: maxillary sinus augmentation via a lateral window approach(SLAW), surgical complications, cone beam CT(CBCT), 3D reconstruction

摘要： 目的：报道1例严重上颌骨萎缩伴上颌窦囊肿及窦腔间隔的患者诊治经过，总结数字化种植模拟分析经验，以减少并发症，提高此类病例手术成功率。方法：术前锥形束CT检查，三维显示上颌窦囊肿合并窦腔骨性间隔，保留囊肿行上颌窦侧壁开窗提升术，术中剥离底壁后方与窦腔间隔连接处黏膜时发生穿孔，覆盖可吸收胶原膜，植入骨粉。1年后植入种植体并固定修复，修复1年后行锥形束CT检查。结果：上颌窦侧壁开窗提升术后1年，上颌窦提升高度理想，囊肿形态完整。植入种植体并修复1年后，骨量稳定，囊肿形态完整，种植体稳定，咬合关系良好。结论：正确的术前诊断、充分的术前准备以及三维数字化模拟种植，将有助于降低上颌窦侧壁开窗提升术的手术风险，减少并发症，提高手术成功率。
