Implant microdesigns and their impact on osseointegration

Researchers are in constant search for the ideal implant surface condition in an attempt to improve osseointegration of the implant and to increase bone-to-implant contact. Although introduction of rough surfaces was able to overcome a lot of limitations that presented with machined surfaces, they are still incapable of ensuring predictable results and guaranteed success. Various techniques in implant surface modifications have been proposed, all aimed at improving bone formation around dental implants. Understanding how surface modification of dental implants can impact osseointegration might help the clinician to maximize the success rate of implants and diminish the complications that can be encountered after their placement. In view of that, this article is aimed at assessing the different surface conditioning techniques available and will present a review of the literature that focuses on the influence of microdesign of dental implants on their osseointegration.
