Efficacy of Photobiomodulation Therapy for Pain Relief and Soft Tissue Wound Healing After Dental Implant Surgery
Share
This double-blind randomized clinical trial investigated whether Photobiomodulation Therapy (PBMT) could reduce pain and improve soft tissue healing after dental implant surgery. The study involved 21 patients with 42 implants, where laser treatment was applied to one side and placebo treatment to the other for comparison.
Key Findings
- PBMT significantly reduced postoperative pain compared with the placebo-treated side.
- It also improved soft tissue wound healing at multiple follow-up periods (3, 7, and 14 days after surgery).
- The laser-treated side showed better healing scores and faster recovery.
- The therapy used 660 nm and 810 nm diode lasers, suggesting PBMT may help support tissue repair and inflammation control after oral surgery.
Clinical Importance
PBMT appears to be a promising non-invasive adjunct treatment after dental implant surgery, helping improve patient comfort and healing outcomes without replacing standard postoperative care.
Limitations
- Small sample size (21 patients)
- Focused only on short-term healing and pain relief
- More large-scale studies are needed to confirm long-term effectiveness.
Conclusion
Photobiomodulation Therapy may help accelerate soft tissue healing and reduce pain after dental implant surgery, making it a useful supportive therapy in dental recovery.
Simple takeaway: PBMT showed promising benefits for faster healing and less pain after dental implant procedures
