目的：探讨骨挤压器行上颌窦底内提升不植骨同期植入种植体术在口腔种植中的应用及临床效果。方法15例上颌后牙缺失者，种植区剩余牙槽骨高度（residual bone high，RBH）为4～8 mm，用骨挤压器行上颌窦底内提升不植骨同期牙种植术，共植入ITI种植体17颗，术后6个月行种植体上部冠修复。通过两年的临床观察，分析种植体存留率、评价种植体周围软组织健康状况，拍摄X线片评价种植体与周围骨组织结合状况、种植体颈部边缘骨吸收状况和窦底提升后新骨形成状况。结果观察期内17颗种植体存留率为100％，术后6个月X线片检查种植区窦底平均提升高度为3．12 mm（2．03～4．13 mm），种植体骨结合良好，术后每次X线复查种植体颈部周围骨水平吸收＜0．2 mm。结论骨挤压器行上颌窦底提升不植骨同期种植术方法可靠，效果肯定，能有效治疗窦底RBH不足的上颌后牙缺失者。
目的：探討骨擠壓器行上頜竇底內提升不植骨同期植入種植體術在口腔種植中的應用及臨床效果。方法15例上頜後牙缺失者，種植區剩餘牙槽骨高度（residual bone high，RBH）為4～8 mm，用骨擠壓器行上頜竇底內提升不植骨同期牙種植術，共植入ITI種植體17顆，術後6箇月行種植體上部冠脩複。通過兩年的臨床觀察，分析種植體存留率、評價種植體週圍軟組織健康狀況，拍攝X線片評價種植體與週圍骨組織結閤狀況、種植體頸部邊緣骨吸收狀況和竇底提升後新骨形成狀況。結果觀察期內17顆種植體存留率為100％，術後6箇月X線片檢查種植區竇底平均提升高度為3．12 mm（2．03～4．13 mm），種植體骨結閤良好，術後每次X線複查種植體頸部週圍骨水平吸收＜0．2 mm。結論骨擠壓器行上頜竇底提升不植骨同期種植術方法可靠，效果肯定，能有效治療竇底RBH不足的上頜後牙缺失者。

Objective To investigate the effect of osteotome sinus floor elevation with immediate implantation and without bone graft-ing in the implant restoration.Methods 15cases with 4~8mm height of residual bond in the posterior maxilla were placed maxillary sinus lifting techniques and simultaneous implant 17 ITI placements without bone grafting.The implants were restored after six months.All the pa-tients were followed up for 2 years to evaluate the implant survival rate and the peri-dental implant tissue condition.X-ray measurements were performed to evaluate bone remodeling around the implant.Results The cumulated survival rate was 100%.Six months later,it was found that bone height of sinus floor on implants was elevated about 3.12mm,and the alveolar bone was well osteointegrated with the implants.Each X-ray examination of bone around the implant neck level absorption was less than 0.2mm.Conclusion The technique of osteotome sinus floor elevation and immediate dental implantation without bone grafting has satisfactory therapeutic effect.It could be used in the maxillary posterior area implant placement.
