The document discusses the history of dental implants in the United States from 1891 to present day. It covers early implant designs like the Greenfield implant from 1909, the first two-stage threaded root form implant from 1938, and the introduction of new metals like titanium after WWII that improved biocompatibility. It also discusses the evolution of subperiosteal implants from the 1960s-1970s and the introduction of the "O" ring attachment system in 1973. More recent implant designs discussed include blade implants from the late 1960s-1970s and the ISI immediate load implant system introduced in 2002.

5. The Greenfield Implant was used and further developed from 1909 until the late 30s and early 40s. First constructed of platinum and later Vitalium ( chrome cobalt) by work carried on by Moses and Alvin Strock. Note: Greenfield later opened up the apex and with a trephine bur created a bone pedestal onto which the implant was tapped creating and immediate load root form implant.

67. The introduction of the 2 stage osseous integrated implant changed Implant Dentistry until the reintroduction of the immediate load, one stage implant. “ How do you restore a bolt?” The lab became biomedical engineers. Cost of implants gadgets, and special lab fees have made it almost impossible to Treat with the current standard of care for a missing tooth! Different platforms Direct or Indirect ? Cone beam X-ray Mini Implants What next?
