The present invention enables modification of an intraosseous implant device that is not only biologically non-inert, but can stimulate bone and vascular growth; decrease localized inflammation; and fight local infections. The method of the present invention provides a fiber with any of the following modifications: (1) Nanofiber with PDGF, (2) Nanofiber with PDGF+BMP2, and (3) Nanofiber with BMP2 and Ag. Nanofiber can be modified with other growth factors that have been shown to improve bone growth and maturationBMP and PDGF being the most common. Nanofiber can be applied on the surface of the implant in several ways. First, a spiral micro-notching can be applied on the implant in the same direction as the threads with the nanofibers embedded into the notches. Second, the entire surface of the implant may be coated with a mesh of nanofibers. Third, it can be a combination of both embedding and notching.

The present invention relates to a dental composition comprising a radically polymerizable compound, a redox initiator system comprising one or more clathrate compounds comprising a host molecule and one or more guest molecules, wherein the host molecule is selected from cyclodextrines, crown ethers, cucurbituriles and calixarenes and the one or more guest molecules are reducing agents, and an oxidizing agent. Furthermore, the present invention relates to a use of the redox initiator system in a dental composition.
