Radiographic evaluation of interdental bone resorption in immediate implant surgery after LT-IR 660 nanometer low-level laser therapy

Abstract

Introduction: Although the benefits of Low-Level Laser Therapy (LLLT) in soft tissue healing have been demonstrated, the effects of laser on bone have still remained controversial. This study investigated the effect of postoperative 660 nm LLLT on the radiographic interdental bone loss of immediate implants.

Methods of study: 30 patients who were referred to the Department of Oral and Maxillofacial Surgery for tooth extraction and placement of immediate implant, were selected and divided into two groups: laser (intervention) and no-laser groups (control). Immediately after tooth extraction, the implant was inserted into the tooth socket area. 660 nm LLLT was immediately started after surgery and was repeated for three times per week for 2 weeks. Bone quantification at the implant site was assessed using periapical intraoral radiograph and computerized software immediately after the surgery and also by passing 4 months from that.

Results: This study showed a statistically significant difference in mean interdental bone resorption between the mesial and distal sides of the two groups and this was lower in the laser group compared to the no-laser group.

Conclusion: The results of this study suggest LLLT can be effective on reducing the interdental bone resorption in immediate implant placement. This may indicate the positive effect of LLLT on bone resorption reducing.
