Abstract

In the last decades, the dental implants treatment has become an efficient method of treatment for patients, to replace missed teeth. Subsequently, with advancing of the implant therapy, the number of complications that arise over time is on the increase at clinics. Biofilm development around the implants is thought to be the most important responsible to late failure implants. Since that bacterial colonization of the surfaces starts after their exposure to the oral environment, abutment has a pertinent clinical interest due to its supra and subgingival localization and intimate contact of these substrates with the peri-implantar tissue. While traditional studies concentrate in methods to change dental implants surfaces to improve the osseointegration process, we are proposing to develop a new coating to titanium abutments, focusing in inhibiting the bacteria growth to prevent the peri implantitis disease. To this end, our purpose is to modify the physiochemical properties of titanium materials with different types of coating, and evaluate its effect on the development of a cultivable polymicrobial community representative of the oral cavity in combination with a bacterial growth medium (SHI-FSMS) containing saliva and blood components, as model system for bacterial attachment and biofilm formation.
