Comparative analysis of osteointegration in photostimulated dental implants: 650-976 nm diode lasers versus growth factors.

Abstract

This study aimed to assess the effectiveness of photobiomodulation therapy (PBM) and leukocyte plasma-rich fibrin (L-PRF) in enhancing or accelerating osseointegration by promoting dental implant stability. The study included 15 patients lacking posterior mandibular teeth. Each participant received two implants in the mandibular edentulous area at the lower posterior region. The implants on the right side were categorized into three groups: Group A (650 nm laser), Group B (976 nm laser), and Group C with L-PRF (10 implants each). The left side served as the control. L-PRF was applied at the implant base before placement. Laser irradiation was performed on the buccal and lingual sides of the implants. Osseointegration was assessed using the AnyCheck system from Neo-Biotic Company. The Implant Stability Quotient (ISQ), ranging from 0-100, was measured post-operatively and after three months. There was a significant increase in stability after three months, particularly with 650 nm laser photobiomodulation followed by L-PRF application. The differences in ISQ among the three groups were statistically significant. After three months, implant stability was significantly higher both buccally and lingually in Group A, using powers of 75 mW and 100 mW, respectively, compared to the control (P <0.01). These findings indicate that PBM and L-PRF can significantly enhance osseointegration and improve dental implant stability in the posterior mandible. Patients and clinicians should consider the potential benefits of these interventions in implant dentistry, especially in cases involving the posterior mandible, where stability is crucial for successful implant outcomes.
