摘要/Abstract

摘要： 目的: 研究拟种植区冠根向的皮质骨和松质骨厚度比率(cortico-cancellous thickness ratio, CCTR), 评估其与植体稳定性的相关性。方法: 纳入符合标准的57例患者(65个缺牙位),种植术前将患者CT图像导入动态导航软件, 设计完成后测量并计算CCTR, 术后即刻及修复前记录种植体稳定性系数(implant stability quotient, ISQ)。Pearson相关系数评估CCTR与ISQ的相关性。结果: CCTR与初期ISQ值和二期ISQ值之间均存在正相关(r=0.708,P<0.01;r=0.568,P<0.01),上下颌后牙区初期ISQ值、二期ISQ值、 CCTR均值有显著性差异(P<0.01)。结论: CCTR可作为测量拟种植区骨质的客观指标之一, 对植体稳定性的评估具有重要意义。

Abstract: Objective: To assess the correlation between preoperative virtual peri-implant cortico-cancellous thickness ratio (CCTR) and implant stability. Methods: Fifty-seven patients who met the criteria were included. CT images of the patients were imported into the dynamic navigation software before the implant surgery, and the CCTR was measured and calculated after the design was completed, and the stability of the implants (ISQ) was recorded immediately after the surgery and before the restoration. Pearson correlation coefficients were used to assess the correlation between CCTR and ISQ. Results: There was a positive correlation between CCTR and both initial ISQ values and phase Ⅱ ISQ values (r=0.708, P<0.01;r=0.568, P<0.01), and there was a significant difference between initial ISQ values, phase Ⅱ ISQ values, and mean CCTR values in the maxillary and mandibular posterior region (P<0.01). Conclusion: CCTR can be used as a new objective index for measuring bone quality in the proposed implant area and is important for the assessment of implant stability.
