Abstract
An endosseous dental implant for guided regeneration of gingival tissue onto the implant and method of producing the same is prepared by coating a region of the implant with biocompatible, random or aligned microfibers or nanofibers to which gingival epithelial and connective tissue cells may become attached. The fibers may be degradable or nondegradable. The extracellular matrix of new connective tissue forms and connects to the implant surface, guided by the nanofibers or microfibers. The coated implant prevents bacterial biofilm formation, which can cause detrimental resorption of crestal bone and lead to implant failure. The implant surface supports improved tissue bonding and provides a cost-effective approach to coating the dental implant surface with biomimetic fibers to enhance gingival or other tissue regeneration directly onto the implant surface.
