Immediate dental implant placement in the molar region is critical, because of the high amount of bone loss and the discrepancy between alveolar crest thickness and the implant platform. Laser phototherapy (LPT) improves bone repair. The aim of this study was to evaluate the human alveolar bone repair 40 days after molar extraction in patients submitted to LPT with adjunctive phytotherapeutic agent (PTA).
Twenty patients were selected for this randomized controlled clinical trial; 10 underwent LPT (laser group) with a GaAlAs diode laser (808 nm, 100 mW, 0.04 cm2 , 75 J/cm2 , 30 s per point, 3 J per point, at five points). The LPT + PTA patients (n = 10) were the socket was first irradiated with laser followed by C.Quadrangularis liquid application. Forty days later, the tissue formed inside the sockets was analyzed by micro-computed tomography. Data from the two groups were compared with Student’s t-test.
The relative bone volume was significantly higher in the LPT +PTA group (P < 0.0001). The results suggest that LPT+ PTA is able to accelerate alveolar bone repair after molar extraction, leading to a more homogeneous trabecular configuration represented by thin and close trabeculae.
