摘　　要：目的评估应用短种植体联冠修复下颌后牙牙列缺损的短期临床疗效。方法选择2008年1月至2013年1月在中国医科大学附属口腔医院种植中心植入2枚种植体并用联冠修复下颌后牙牙列缺损的患者65例,共植入130枚种植体。其中,31例患者植入62枚短种植体(长度≤8.5 mm)作为短种植体组,34例患者植入68枚标准种植体(长度≥11.5 mm)作为对照组。记录并统计分析病例在手术当天及复诊时的相关临床资料,包括种植体累积成功率、生物机械并发症、边缘骨吸收、临床冠根比等。结果两组各有2枚种植体失败;两组种植体累积成功率、并发症及边缘骨吸收比较差异无统计学意义(P>0.05);短种植体组临床冠根比显著大于对照组(P<0.01)。结论在严格控制适应证的情况下,对于骨量不足的患者应用短种植体修复下颌后牙牙列缺损能够取得理想的临床效果,同时可以降低手术风险,并减轻患者经济负担。Objective To evaluate the short-term clinical effect of splinted short implants in the partly edentulous man- dible of posterior regions. Methods Totally 65 patients （ 130 implants）who received short implants or standard implants to restore dentition defect in mandible of posterior regions during the period between January 2008 and January 2013 at the Implant Center of Hospital of Stomatology, China Medical University were selected, including 31 patients with 62 short implants （length ~〈 8.5 ram）as the short implant group and 34 patients with 68 standard implants （length ~〉 11.5 ram）as control group. Relevant clinical data was recorded and analyzed, such as cumulative success rate, biomechanica] complications, marginal bone loss and Crown/Implant ratio. Results Two implants failed in both short implant group and control group. No significant differences in cumulative success rate, biomechanical complications and marginal bone loss were found between the two groups （P 〉 0.05）. The clinical Crown/Implant ratio in short implant group was signifi- cantly greater than that of the control group（P 〈 0.01 ）. Conclusion In the case of strict control of indications, the appli- cation of short implants to restore edentulous mandible of posterior regions for those who had bone defect can achieve more satisfactory clinical results, and additionally reduce the operation risk and the economic burden of patients.
