目的：评估短种植体在较低牙槽骨高度上颌后牙区使用的临床效果，探讨其使用价值。方法2009—2011年，选取窦底骨高度为3~6 mm患者26例，共植入37枚短种植体，随访25~48个月(平均36个月)，回顾其临床及影像资料，采用Buser和Cochran存留标准评估短种植体存留率。结果37枚短种植体一例修复前失败，成功率97.3%。复查X线片种植体颈部边缘骨吸收均小于1.5 mm。结论对于窦底骨高度严重受限的病例(3 mm≤高度≤6 mm)，短种植体可以取得良好的且与常规长度种植体相同的稳定性。

Objectives To evaluate the clinical efficacy of short implant used in the marginal bone loss posterior regions and to dis-cuss the use value of the short implant. Methods A retrospective study design was adopted. The clinical and radiographic data of 37 short implants in 26 patients (3 mm≤bone height≤6 mm) from 2009 to 2011 were collected after 25 to 48(mean 36) months′follow-up to estimate the clinical result. The survival rate was evaluated according to Buser and Cochran′S survival criteria. Results The over-all cumulative survival rate was found to be 97. 3% and 1 case early failure before restoration in the maxillary molar region was ob-served. The mean loss in margin bone height was less than 1. 5 mm. Conclusions In the case of low alveolar ridge height of maxillary posterior region (3 mm≤H≤6 mm),survival rate of short implants over an average period of 36 months was favorable and comparable with longer implants.
