To measure dental implant stability by two noninvasive methods which are vibration characteristics of the periodontium Periotest® and resonance frequency analysis Osstell. The objective of this comparative study was to assess the correlation of these 2 techniques in clinic. Materials and Methods: Implant stability of 54 clinically stable unloaded implants in 10 males and females (mean age: 52.05 ± 8.42) was measured in triplicate by Osstell and Periotest. The measurements were taken first in the same day of the surgery and the second was 4 weeks later. Statistical analysis was performed with SPSS 22.0 (P < 0.05). Results: The mean values were 75.90 ± 5.13 ISQ for the resonance frequency analysis and - 4.31 ± 1.43 PTVs for Periotest. There was no significant difference in first and the second measurements accordance with gender. However, a significant difference was shown in ratio of percentage change for both PTV and ISQ values in female patients. There was a positive strong correlation between mean percentage changes of PTV and ISQ values (P = 0.811, P = 0.001). The only significant difference between ISQ values and implant length was observed at 4 weeks (P = 0.037).
Although Periotest values appear to be more susceptible to clinical conditions, both measuring techniques are applicable in the assessment of implant stability.
使用两种非侵入性方法（牙周组织的振动特性 Periotest® 和共振频率分析 Osstell）来测量种植牙的稳定性。本研究的目的是评估这两种技术在临床中的相关性。
对 10 名男性和女性（平均年龄：52.05 ± 8.42）的 54 个临床稳定、未负重种植体进行三次 Osstell 和 Periotest 测量。第一次测量在手术当天进行，第二次测量在 4 周后进行。使用 SPSS 22.0 进行统计分析（P < 0.05）。
共振频率分析的平均数值为 75.90 ± 5.13 ISQ，Periotest 的平均数值为-4.31 ± 1.43 PTVs。性别方面，第一次和第二次测量的平均值没有显著差异。然而，女性患者的 PTV 和 ISQ 值的百分比变化比值存在显著差异。PTV 和 ISQ 值的平均百分比变化之间存在正强相关（P = 0.811，P = 0.001）。仅在第 4 周时观察到 ISQ 值与种植体长度之间存在显著差异（P = 0.037）。
虽然 Periotest 值似乎更容易受到临床条件的影响，但这两种测量技术均可应用于评估种植牙的稳定性。
