  • Patent number: 11058521
    Abstract: 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 maturation—BMP 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.

  • Patent number: 10813729
    Abstract: A method of manufacturing a permanent prosthesis for attachment to a dental implant installed in a mouth of a patient includes scanning a patient specific temporary prosthesis (PSTP) to obtain scan data. The PSTP is attached to the dental implant in the mouth of the patient. Gingival tissue surrounding the PSTP is permitted to heal in the mouth of the patient. In response to aesthetics of the healed gingival tissue surrounding the PSTP in the mouth of the patient not being acceptable, the PSTP is physically modified by (i) removing material from the PSTP, (ii) adding material to the PSTP, or (iii) both. The modified PSTP is scanned and a permanent prosthesis is fabricated as a replica of the modified PSTP using scan data generated from the scan of the modified PSTP.
