Accelerated Implant Stability After LED Photobiomodulation

Accelerated Implant Stability After LED Photobiomodulation

Apr 27, 2023


Previous studies have demonstrated more rapid dental implant integration as a result of the biostimulatory effect of laser and light emitting diode (LED) photobiomodulation in both in vitro and in vivo models. It was the purpose of this clinical trial to examine the effect of the extra-oral application of LED treatment on implant stability, as assessed by resonance frequency analysis (RFA).


28 patients had 45 dental implants placed in either the maxilla or mandible. 19 patients had an OsseoPulse LED device (Biolux Research Ltd, Canada) positioned over the surgical site by the patient and utilized on a daily basis of 20 mW/cm2 for 20 min at a wavelength of 618 nm for 21 days. All implants were were tested for primary stability with an Osstell Mentor RFA device (Osstell AB, Sweden) at the time of implant placement, and at 14, 30, 60 and 90 days.


Patients treated with the LED device demonstrated significantly (p<0.05) improved dental implant stability at day 14, day 30 and day 60. No significant differences were seen at the time of implant placement or at day 90.


The results have demonstrated that the LED photobiomodulation accelerated implant stability as compared to the untreated dental implants in this investigation. These results may suggest that LED photobiomodulation may allow for more rapid integration of dental implants.
