摘要
目的:观察使用骨挤压器经牙槽嵴顶入路提升上颌窦底、同期植入种植体的临床效果。方法:对104例单侧或双侧上颌后牙缺失患者,经牙槽嵴顶入路行上颌窦底提升,同期植入种植体,共126颗。全部病例均行X线曲面断层片,其中30例在后期随访中行螺旋CT扫描及三维重建。结果:上颌窦剩余牙槽骨平均高度为9.16mm(5～11mm),用骨挤压器平均提升上颌窦底高度3.95mm(2～6mm),无1例上颌窦黏膜穿孔。随访16～82个月,成功率达100%,所有病例均无上颌窦并发症。CT扫描及三维重建显示,种植体顶端有一层完整骨质覆盖,种植体完全埋入骨质中。结论:应用骨挤压器,经牙槽嵴顶入路行上颌窦提升同期植入种植体,与上颌窦外提升术相比,手术创伤小、操作简便、并发症少,其近、远期效果均满意;螺旋CT扫描及三维重建可作为上颌窦提升种植体植入术后判断手术效果的有效手段。
PURPOSE： To evaluate the clinical results of maxillary sinus floor elevation technique with bone condensers on implantation. METHODS： 104 patients underwent maxillary sinus floor elevation and 126 implants were inserted and restored. Clinical examination and radiographs were conducted. Spiral CT scanning and three-dimensional reconstruction was performed among 30 cases during follow-up. RESULTS： All the patients with 9.16mm （5-11mm） height of residual bone in the posterior maxilla underwent sinus floor elevation with simultaneous implant placement using bone condensers. The elevation height was 2-6mm. The follow-up time was 16-82 months. No sinus complication was observed during the follow-up period. The survival rate was 100%. Spiral CT scanning and three-dimensional reconstruction showed that dental implants were submerged in the alveoli around, their tops were covered with bone. CONCLUSIONS： With bone condensers, maxillary sinus floor elevation with simultaneous placement of implants from the top of alveoli was a predictable and safe technique. There were no implants loose or lost, no clinical complaint of maxillary sinus area, and X- ray examination showed well osseointegration.
