Branemark did not invent dental implants. He pioneered osseointegration , restorative designs of the edentulous patient, and the root-form dental implant.
Dental implants were around in this country far before 1982 when Zarb and Schmitt in Toronto reported similar North American success as found with the Branemark clinic and thus launched the belief that screw-root form dental implants could become widely accepted as alternative to traditional prosthodontics and could be predictably successful on a long-term basis.
Prior to this there were many centers around N America placing subperiosteals (1948), blades (1966), ramus frames (1970), transosteal "mandibular staple", and endodontic endosteal implants (1943) etc.
Perio didn't get involved until later in the game, OSes and Prostho guys were the pioneers. I'd, however, venture to say that the endodontists were doing vitallium endodontic "implants"before periodontists and oral surgeons... i.e. 1943? (Strock AE, Strock MS. Method of reinforcing pulpless anterior teeth. J Oral Implantol. 1987;13(3):527-30. [reprint from 1943]).
Now you could argue that Branemark introduced the root form screw-type dental implant in N America. Now no-one can really argue that he is the pioneer of osseointegration and is the father of implant dentistry as we know it today. Even if I still see subperiosteals, blades, and transosteals around, the Branemark concept is still king 🙂.
Best part of the argument for all you posters that want to flame this post regarding which specialty is best for implants... Branemark is a bioengineering PhD scientist and anatomist who came up with the concept, not a dentist, who wanted to help edentulous "amputees" and cleft patients. A prosthodontic problem with a surgical approach.
