Abstract
The aim of this study was to evaluate the osseointegration of two implant surfaces (laser treated &
sandblasted/acid etched) with implants placed immediately in fresh extraction sockets.
Methodology: Thirty implants were used to treat patients with badly broken teeth indicated for
extraction & immediate implant placement. The patients were divided equally into 2 groups, the first
group received laser surface treated implant & the second group received sandblasted/acid etched
treated implant, implant stability using a Resonance Frequency Analysis device was measured
immediately after implant insertion and at 2,4,6,8,12 weeks interval.
Results: No statistically significant difference was recorded between both laser surface treatment &
sandblasted/acid etched surface treatment implants regarding to the ISQ values at any time interval.
But in comparing the ISQ value of each implant within the same group to evaluate the effect of time
on implant stability, a significant decrease in implant stability from time of implant insertion to the
4th week was observed in SLA group.
Conclusion: Both types of laser surface treatment and sandblasted /acid etching surface treatments
have high rates of osseointegration in immediate implant placement cases with an observed
superiority for the laser surface treatment
