The first evidence of implants dates back to 600 A.D. in the Mayan population. There are reports that the ancient Egyptians attempted intra-osseous implantation of animal teeth or teeth carved from ivory in to the mouth of their court women. The medieval period (1000 to 1799 A.D.) of implant dentistry was primarily concerned with transplantation of teeth. Albucusis, an Arab surgeon fabricated implants made of ox bone, ivory and shells.
