Comparative Analysis of MMP-8 and MMP-9 Concentrations in Crevicular and Peri-Implants Sulcular Fluids.

The concentrations of MMP-8 and MMP-9 were measured in the crevicular and the peri-implant sulcular fluids at the different stages of the prosthetic treatment. The concentration MMP-8 and MMP-9 in the peri-implant sulcular fluids were significantly higher (p<0.05) then in the gingival crevicular fluid.
