Abstract

Purpose
This study aimed to evaluate the stability of two implant groups treated either only with sandblasting and acid etching or photoactivation af ter sandblasting and acid etching, using resonance f requency analysis (RFA).
Materials and Methods
We investigated 50 implants in 25 patients (12 men and 13 women). Twenty-five implants were treated with sandblasting and acid etching, and 25 with photoactivation. We recorded the implant stability quotient (ISQ) value on the day of implant placement and consecutively every 2 weeks f or 16 weeks f or each implant. RFA was used f or the direct measurement of implant stability. We compared mean ISQ values using a repeated-measures analysis of variance test.
Results
The mean ISQ values at surgery and 16 weeks in implants treated only with sandblasting and acid etching were 77.8 ± 6.7 and 83.2 ± 2.5, respectively, while in those treated with f urther photoactivation were 78.9 ± 5.3 and 84.1 ± 3.3, respectively. The photoactivated implants showed higher ISQ values than those without photoactivated surface treatment. However, there were no significant differences between the two implant groups.
Conclusion
Both implant groups showed high implant stability in clinical practice. The photoactivated implant surf ace appears to have higher implant stability than that without photoactivation by increasing the hydrophilic surface.
