【摘要】：目的通过共振频率分析仪测量种植体的稳定系数(ISQ),以明确生骨片对后牙区种植体骨结合状况的影响。方法选取48例患者共101颗DENTIUM种植体作为研究对象,其中对照组24例患者(50颗种植体)按种植术后常规处理;余24例患者(51颗种植体)作为处理组,在种植术后常规处理的基础上加服生骨片。于种植术后即刻,术后4、8、12周利用共振频率分析仪测量ISQ值,将2组患者所测得的ISQ值进行比较。结果处理组上、下颌骨种植体于术后即刻、术后12周所测得的ISQ值与对照组相比,差异无统计学意义(P0.05);术后4、8周所测得的ISQ值优于对照组,差异有统计学意义(P0.05)。处理组和对照组下颌骨种植体于术后即刻,术后4、8和12周所测得的ISQ值优于上颌骨种植体,差异均具有统计学意义(P0.05)。结论种植术后早期服用生骨片,有助于加快种植体骨结合,提高术后4、8周种植体的ISQ值,进而降低种植体-骨关键愈合阶段的脱落风险,保证种植术的成功率,提供临床修复的时机。
[Abstract]:Objective to measure the stability coefficient of implants and to determine the effect of bone graft on the bone bonding of implants in posterior dental region by resonance frequency analyzer (RFA). Methods A total of 101 DENTIUM implants were selected from 48 patients. The control group (24 patients with 50 implants) was treated routinely after implantation, and the remaining 24 patients with 51 implants were treated as the treatment group. On the basis of routine treatment after implantation, we took raw bone slice. The ISQ values were measured by resonance frequency analyzer immediately after implantation and at 812 weeks after implantation. The ISQ values of the two groups were compared. Results in the treatment group, the ISQ values of mandibular implants were not significantly different from those of the control group immediately after operation and 12 weeks after operation, but the ISQ values measured at 4 and 8 weeks after operation were better than those in the control group (P 0.05). The ISQ values of mandibular implants in the treatment group and the control group were significantly higher than those in the maxillary implants at 8 and 12 weeks after operation, and the differences were statistically significant (P 0.05). Conclusion early use of bone graft after implantation is helpful to accelerate implant bone union, increase ISQ value of implant at 4 ~ 8 weeks after implantation, reduce the risk of exfoliation in the critical healing stage of implant-bone, and ensure the success rate of implant-bone implantation. Provides the opportunity for clinical repair.
