インプラントを歯科に初めて応用したのは誰
The early part of the 20th century saw a number of implants made of a variety of materials. One of the earliest successful implants was the Greenfield implant system of 1913 (also known as the Greenfield crib or basket). Greenfield's implant, an iridioplatinum implant attached to a gold crown, showed evidence of osseointegration and lasted for a number of years. The first use of titanium as an implantable material was by Bothe, Beaton and Davenport in 1940, who observed how close the bone grew to titanium screws, and the difficulty they had in extracting them. Bothe et al. were the first researchers to describe what would later be called osseointegration (a name that would be marketed later on by Per-Ingvar Brånemark). In 1951, Gottlieb Leventhal implanted titanium rods in rabbits. Leventhal's positive results led him to believe that titanium represented the ideal metal for surgery.
