Efeito da PBMT de comprimento de onda vermelho na osseointegração de implantes em área enxertada.

Abstract

This study evaluated if the red light photobiomodulation (PBMT), influences the osseointegration of implants installed in areas grafted with deproteinized bovine bone (DBB). Thirty-two rats were randomly distributed in 2 groups. The groups were divided according to the irradiation protocol applied: CTR – Implants not submitted to PBMT; RL – Implants treated by red light PBMT. The animals underwent grafting procedures on the tibias and after 60 days the implants were installed. After the implant’s placement, the PBMT was performed through by the application of 4J around the implants in the RL groups. After 15 and 45 days, the animals were euthanized (n= 8). Analyzes of the osseointegration by the bone and implant contact (%BIC) and by the bone between the threads (%BBT) were performed. There was no statistical difference between the RL and CTR groups for both %BIC and %BBT. The RL 45 days group presented higher %BBT when compared to the RL 15 days group. The red light photobiomodulation did not improve the osseointegration of implants installed in the grafted area.
