摘　　要：目的探讨下颌单颗后牙种植即刻修复临床应用的可行性及临床应用的影响因素和注意事项。方法选择31例患者共31颗下颌后牙种植患者,牙拔除后3-6个月,植入XIVE种植体,即刻完成临时固定修复,3-4个月取模制作终修复体,对照组29例患者29颗后牙,行非埋植式种植手术,术后3-4个月取模制作终修复体。随访12-24个月,观察种植体的存留率,种植体周围软硬组织情况,两组患者主观满意度。结果即刻修复组患者牙龈充盈指数及满意度均高于对照组。即刻修复组中,31枚XIVE种植体周围牙龈乳头充盈指数平均得分数值为（2.35±0.70）,而对照组种植体周围牙龈乳头充盈指数平均得分数值为（1.84±0.74）。两组患者主观满意度VAS平均值分别为（91.5±7.5）分、（85.8±8.1）分;两组种植体均获得良好的骨结合,存留率均为100%,种植体无松动,种植体周围未见病理性骨吸收。结论在严格掌握适应证的前提下,应用正确的手术技巧和恰当的调磨咬合,下颌单颗后牙即刻修复可以获得理想的临床效果。Objective To evaluate the clinical effect of immediate implant restoration in lower posterior teeth.Methods 31 XIVE implants were placed in lower posterior teeth of 31 patients. The temporary fixed resin crowns were fabricated immediately and final restorations were finished in 3 - 4 months. The control group used nonsubmerged implants and were restored with final crowns in 3 - 4 months. The tracking survey was taken from 12 to 24 months after final restoration. The patient satisfaction,papilla index score（ PIS） and implant survival rate were evaluated between the two groups. Results PIS of patients with immediate restoration reached（ 2. 35 ± 0. 70） in average compared（ 1. 84 ± 0. 74） in control group. The patient satisfaction reached（ 91. 5 ± 7. 5） with immediate restoration,compared with VAS score in average of（ 85. 8 ± 8. 1） in control group. All implants in both groups achieved osseointegration and received 100% survival rate. Conclusion With proper technique in surgical and restoration procedure,immediate restoration after implant insertion in posterior madible has similar clinical success compared with delayed restoration.
