Dental implants surface roughness can influence bacterial site infection? A clinical in vivo prospective clinical study on 109 patients, preliminary results on radiologic evaluation.

Dental implants are intended to provide long-term reliable dental restorations. Limited data exist on the comparison between different implant surfaces. This study aims to investigate if the surface topography and roughness might increase the bacterial adhesion and intensify the possibility of implant failure in patients with and without a previous history of periodontal disease. Surface topography and roughness are some of the aspects that can be easily manipulated by resorting to post-production surface treatments and that play an important role in the determination of cellular response, influencing adhesion, adsorption and differentiation .
