Is Low-level laser therapy and gaseous ozone application effective on osseointegration of immediately loaded implants?

Purpose: The purpose of this study was to investigate the effects of biostimulation lasers and ozone therapy on osseointegration of immediately loaded implants.

Materials and Methods: A total number of 100 implants (DTI Implant Systems) were applied to 25 patients evenly. Temporary crowns were applied to each patient on the same session as the surgery. Implants were divided into four treatment groups (Group 1: low-level laser therapy (LLLT) group, Group 2: ozone therapy group, Group 3: different protocol of ozone therapy group, and Group 4: control group) each with 25 implants. The irradiations were performed with a gallium-aluminum-arsenide diode low-level laser (Laser BTL-4000) to Group 1. Ozone therapy was performed using an ozone generator (OzoneDTA) with an intraoral probe to Group 2 and Group 3.

Results: In this study, the overall implant survival rate was 92% after a 6-month observation period. The implant stability quotient values were found significantly higher in Group 1 (LLLT group) and Group 3 (different protocol of ozone therapy group) than the other groups (P < 0.05). There was no significant difference in Group 2 (ozone therapy group) and the control group (P > 0.05).

Conclusions: Our results suggest that both LLLT and ozone therapy with prolonged application time are promising methods to enhance bone healing around immediately loaded implants and increase implant stability; however, there is a need for more studies on this subject for these methods to become routine applications.
