640 PLANTATION OF TEETH.

plantation of dead teeth -wliieli remained for years.
No one disputes with Dr. Younger of San Francisco the authorship
of the operation of implantation. The date of his first operation was
June 15, 1885, although Bourdet in 1780 was the first to mention the
operation, stating that " irresponsible persons chiim to make a socket,
and ini])lant into it a tooth." An attempt at partial implantation is
recorded in Dental Cosvios, vol. xix. p. 258.
In order that an intelligent conception may be had of the intimate
nature of the biological conditions which surround the teeth after inser-
tion by either of these operations, it is essential to study the general

foreign bodies.
As all of these operations are" performed under the strictest antiseptic
precautions, the consideration of bacterial influence is omitted at this
juncture. As it is impossible to secure specimens which would show
these several parts in their true relations, the illustrations are neces-
sarily diagrammatic and theoretical.
