摘要： 目的 从实验角度观察初期稳定性对HA涂层、软组织水平、根形种植体即刻种植成功率的影响,以期为临床手术中的操作提供理论依据。 方法 将成年杂种犬双侧下颌后牙区种植位点随机分为两组:实验组(植入ISQ值<50)和对照组(植入ISQ值>65),通过测量植入当时及第4、8、12周种植体ISQ值、同期拍摄CT、光学显微镜下计算种植体-骨结合率,观察植入种植体时不同ISQ值对即刻种植成功率的影响。 结果 种植体植入时ISQ值在28~49区间,对应植入力矩值在10~20 N以内,与对照组相比,即刻种植BLB种植体的成功率无统计学差异。植入后3个月,所有种植体均无松动、脱落,CT示种植体周围骨密度无统计学差异,种植体-骨结合率与对照组相比无统计学意义(P>0.05)。 结论 即刻种植BLB植体初期的ISQ值在28~49区间及68~75区间,对应植入力矩值在10~20 N以内及30 N以上,其成功率无统计学差异。

Abstract: Objective To observe the influence of initial stability on HA coating, soft tissue level and root form implant success rate, in order to provide theoretical basis for clinical surgery. Methods The planting sites in adult mongrel dogs bilateral mandibular posterior tooth areas were randomly divided into experimental group(ISQ<50)and control group(ISQ>65). The implant ISQ value at the time of the implanting, week 4, 8 and 12 were measured and recorded. Meanwhile, CT scan was performed on each animal. The rates of implant osseoiniegration under light-microscopy were computed to observe the impact of different values of ISQ on immediate implantation success rates. Results The initial ISQ values of immediate implant BLB explants ranged 28-49, with corresponding implantation torque values of 10-20 N. There was no significant difference in immediate implantation success rate between the two groups. After 3 months, no implants loosed or dropped. CT scan showed no significant difference in bone density around the implant and implant-bone binding rates between the two groups(P>0.05). Conclusion The initial ISQ values of the immediate implant BLB explants range 28-49 or 68-75, with corresponding implantation torque values being 10-20 N or >30 N. There is no significant difference in the success rates.
