Objectives: To measure dental implant stability by two noninvasive methods which are vibration characteristics of the periodontium Periotest (R) 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 (R). 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). Conclusions: Although Periotest (R) values appear to be more susceptible to clinical conditions, both measuring techniques are applicable in the assessment of implant stability.
