This bone was radiographically similar to that which would surround the blade implant or root form implant of today. Contrary to an earlier-held opinion that these had been inserted after death, Bobbio's x-rays, taken in 1970, showed compact bone formation around two of the implants. He observed that three tooth-shaped pieces of shell had been placed in the sockets of three missing lower incisor teeth. This fragment, now in the Peabody Museum of Archeology and Ethnology at Harvard University, has been studied by Professor Amadeo Bobbio of Sao Paulo, Brazil, a worldacknowledged authority on implants. While excavating at the Playa de 10s Muertas in the Ulloa Valley of Honduras in 193 1, they came upon a mandible fragment of Mayan origin, dating from about 600 AD. The earliest endosseous implant was made of an alloplastic (nonorganic) material and is undoubtedly that which was discovered by the archeological team of Dr. In Europe, Silvestrini, Biavati, Bertolini, Andreasen, Mitchell, Cserepfalvi, Reming, Fong, Nordentram, Hubert, Chercheve and Azoulay contributed to tooth transplants. A tooth bank was developed in 1934 in Hungary by Cserepfalvi, and in Phoenix, Arizona by Pafford in 1953. Chronologically, the most important animal experiments in tooth transplantations had been undertaken by Higgins in dogs (1934), Bodecker and Lefkowitz (1935), Azhausen (1936), Hahn on dogs (1940), Wilfane on rats (1942), Sapiso on cats (1945), Alexander (1945), Maxmen (1945), Aveyzon on salamanders (1950) Fleming in guinea pigs (1952), Lovel and Hopper (1954), Vidain (1954), Sata on rabbits (1955), Agnew on monkeys (1955), Cserepfalvai on dogs (1955), Hammer (1955), Miller (1956), Emmerstein (1956). Numerous transplants and research were completed from 1934 to 1955 and reported upon in literature both in the U.S. In the ensuing years, as information had accumulated about all types of organ transplants interests in transplanting teeth revived. Farrett 1901, Wilkinson 19, Tomkins 1921, Tilley The Great Pioneers 1933. Payne in 1900 used gold and iridium pins, R. Others to mention briefly, all of whom performed successful reimplantations over this general span of time, were Roger of Paris 1844, Vassey 1861, Thompson 1881, Fredel 1887, Curtis 1890, Mendel-Joseph 1890, Fletcher 1891, Zoramenski in 1891 used teeth made of porcelain, Fuller 1899, C. Fauchard and Hunter all believed the main cause of failure was related to the lack of conformity of tooth to socket. The process, of course, awaited the later development of tooth implant materials. At that time, however, nothing was known about immunology, and the failure of transplants was attributed to poor mechanics and techniques. Fauchard reported transplants that lasted a year, and Hunter, of four years. In a like manner a fresh tooth, when transplanted from one socket to another, becomes to all appearances, a part of that body to which it is now attached as much of the one from which it was taken while a tooth which has been extracted from some time so as to lose the whole of its life will never become firm or fixed.” Hunter disagreed with Fauchard over the use of teeth that had been extracted a long time previously. He remarked, “Success of this operation is founded on the desposition of all living substances to unite when brought in contact with one another although they are of different structure and even though the circulation is carried on in one of them. In 1778, he discussed tooth transplantation in his book on teeth. The foremost proponent of tooth transplantation was the Englishman, John Hunter. Other 18th century pioneers included Bourdet, in 1768. 60 YEARS!
