| 目的 探讨锥形束CT(CBCT)应用于临床分析种植体周围骨小梁结构的价值。方法 选择2015年2月至2017年6月,20例缺牙接受种植手术患者,种植手术后即刻与术后6个月分别用CBCT扫描患者颌骨获得影像学图像。两个不同时期共40份CBCT图像通过CTAn 软件分析种植体周围骨小梁结构。结果 术后即刻、术后6个月前后种植体周围骨小梁结构变化差异有统计学意义(P<0.05):术后6个月相对于术后即刻,骨小梁体积百分数(BV/TV)、骨小梁厚度(Tb.Th)、骨小梁数目(Tb.N)数值增加；骨小梁模式因素(Tb.Pf)、结构模型指数(SMI)数值减少。骨小梁间隙(Tb.Sp)术后即刻、术后6个月前后变化差异无统计学意义 (P>0.05)。结论 CBCT可应用于临床分析种植体周围骨小梁结构变化。 |

| Objective To investigate the feasibility of Cone-beam computed Tomography (CBCT) in the clinical assessment of peri-implant trabecular structures.Methods From February 2015 to June 2017,0 patients with teeth lose who received implants were scanned using CBCT to record the radiographic parameters of jaw bone immediately after the surgical procedure,and at the 6th month after operation.During the two periods,forty images were collected,and imported into trabecular bone analysis software CTAn to measure peri-implant trabecular structures.Results There was significant difference in terms of peri-implant trabecular structures between immediate measurement and 6 months post-operation measurement(P<0.05):values of bone volume fraction(BV/TV)、trabecular thi-ckness(Tb.Th)、trabecular number(Tb.N) values were increased and trabecular bone pattern factor(Tb.Pf)、structure model index (SMI) values were decreased after 6 months of operation. There was no significant difference in terms of trabecular separation (Tb.Sp) during the two periods (P>0.05).Conclusion CBCT is reliable to assess peri-implant trabecular structures. |
