Laser Photobiomodulation in Soft Tissue Augmentation: A Clinical Case Report

Aim: To present a clinical case where laser photobiomodulation (PBM) was used as an adjunct to soft tissue augmentation with autologous connective tissue grafts. Case Description: A 42-year-old non-smoking female patient suffering from type II diabetes presented with thin gingival phenotype in the upper anterior region. A subepithelial connective tissue graft (SCTG) was harvested from the palate and placed using a tunneling technique. Adjunctive PBM therapy was applied using a diode laser (λ=635 nm, 100 mW, 4 J/cm²) at multiple time points. Clinical Results: Postoperative healing was uneventful, with reduced discomfort (VAS) reported. At 1, 2-weeks and 3-months follow-up, significant gains in keratinized tissue width and gingival thickness were observed. Conclusion: The postoperative application of PBM represents an innovative and effective approach that supports tissue regeneration and enhances patient well-being. Research findings indicate that this therapy has a positive impact on the body's biological mechanisms, which is particularly important for individuals with impaired healing processes.
