The Influence of Low-Level Laser on Osseointegration Around Machined and Sandblasted Acid-Etched Implants: A Removal Torque and Histomorphometric Analyses

Abstract

Evaluation of the influence of laser application on osseointegration around implants with different surface characteristics is limited. This study aims to evaluate the influence of low-level lasers on the early stages of osseointegration. Ninety-six external hex implants (3.75 mm × 5.0 mm) were placed in 24 rabbits-one machined and one sandblasted acid-etched per tibia. The rabbits were later divided into the laser group, which received a total dose of 24 J/cm(2) of gallium-aluminum-arsenide laser over 15 days, and a control group. At 16 and 30 days after surgery, removal torque and histomorphometric analyses were performed. No statistical differences in removal torque or histomorphometric analyses were verified between laser and control groups regardless of implant surface (P > .05). Time was the only variable presenting significant differences between measurements (P < .05). Low-level laser had no significant short-term effect on bone-to-implant contact and removal torque values regardless of implant surface characteristics.

Effectiveness of Photobiomodulation With Low-Level Laser Therapy on the Implant Stability Quotient at Different Time Intervals: A Randomized Clinical Trial

“…This study focused on assessing outcomes at specific and clinically relevant intervals, indicating it is important to keep in mind that previous research on photobiomodulation in dental implantology has also yielded promising results; however, those studies either used different surface-treated implant systems or assessed outcomes at different or less relevant intervals [16][17][18]. It is also worth noting that a few studies [13,[19][20][21] have shown conflicting or negative results, indicating that the effectiveness of LLLT may vary based on individual patient factors and other variables. Despite this, this study contributes to the prevailing consensus among the majority of studies, leaning toward LLLT being beneficial in enhancing dental implant stability outcomes.…”
