Evaluation of Implant Wettability With Blood vs Autologous Platelet Liquid

Objectives: The physicochemical characteristics of the titanium surfaces, such as wettability, protein binding, cell adhesion and proliferation are tightly related to the osteointegration process of the dental implant in the host bone. The aim of this investigation was to evaluate the wettability of two titanium surfaces, sandblasted and double acid etched (group S/E) and sandblasted (group S), using blood and Autologous Platelet Liquid.
Methods: The surface ultrastructure and roughness were evaluated by scanning electron microscopy (SEM) and atomic force microscopy (AFM). The wettability was measured by the static contact angle (CA) assessed with the sessile drop technique. The fibrin clot derived by blood vs APL was also evaluated by SEM observation.
Results: The fibrin clot structure that develops from blood and APL, knowing that a greater clot, firmly attached to implant can facilitate cell migration to the implant interface. Both of titanium surfaces showed a hydrophobic characteristic, regardless of the wetting liquid used: S surface showed higher CA values, for both the wetting fluids used. Lower CA values on S/E surface are attributable to the different surface energy, which depends on different surface topography (the S surfaces was rougher) and on chemical composition.
Conclusions: The clot obtained from whole blood differs from APL clot due to different cellular composition and fibrin density. Structural differences was present between blood and APL but it is not possible to attest one’s superiority on another clot because other factors such as stability to contraction, elasticity and resistance to fibrinolysis should be investigated.
