生骨片对后牙区种植体骨结合的影响

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（P>0.05）;术后4、8周所测得的ISQ值优于对照组,差异有统计学意义（P<0.05）。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（P<0.05）。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。

Effect of osseointegration in the posterior area by Shenggu pills

Objective This study aimed to investigate the osseointegration condition by measuring the implant stability quotient (ISQ) to study the effect of osseointegration in the posterior area by Shenggu pills.Methods A total of 101 DENTIUM implants were placed in 48 patients. Fifty implants placed in 24 patients were addressed as usual, whereas 51 implants placed in 24 patients were treated with Shenggu pills. ISQ was tested on the day of surgery and consecutively at 4, 8, and 12 weeks. All data were analyzed.Results The efficacy of the treatment group was no much better than that of control group on the day of surgery and consecutively at 12 weeks with no significant difference (P>0.05). The efficacy of the treatment group was significantly better than that of the control group at 4 and 8 weeks (P<0.05). The implants placed in the mandible were significantly better than those placed in the maxilla (P<0.05).Conclusion Early intake of Shenggu pills could accelerate the implant bone union, improve the implants' ISQ, and ensure the success rate of the operation.
