HISTOEY OF DENTAL SURGEKY : 295


published in 1738 in two duodecimo volumes, with forty illustrations. So
far as we laiow it was the first text-book ever written devoted solely to tlie
teeth, their diseases and proper treatment, and so well did it serve its purpose
in that day that it continued to be the authoritative work upon the subject for
nearly a hundred years. In the chapter devoted to "Correction of Irregulari-
ties of the Teeth" he not only mentions the employment by preceding dentists
(and possibly by himself) of some of the simpler methods of moving teeth
finger pressure, thread, silk, little bars or strips of gold or silver, and, occa-
sionally, the forceps—but also describes his own methods which he had devel-
oped.
In his dcFcriptinn of the plan to be followed in certain cases he says
"If the teeth are much out of line and cannot be
corrected by means of threads, it is necessary to use
a band of gold or silver. The band must be neither
too stiff nor too flexible. Two holes are made beside
each other at both e.xtremities. Through these holes
threads are passed by which they are ligated to the
teeth adjoining the one out of line. If the tooth is
inclined outward (labially) the plate is exteriorly ap-
plied," he continues; "if it is bent inward (lingually)
the plate is applied inside of the teeth (arch). By
tlio pressure and support given by the band the in-
clined tooth will be made upright in a short time."
Fig. ( 1 ) ' shows the metal strips before being
placed upon the teeth, while Fig. (3) shows one in
position, designed to move a misplaced lateral incisor
labially into line.
Fig. (3) illustrates his method of applying the
strip to move outward both of the upper laterals.
Fauchard also mentions the use of the file to
remove portions of adjoining teeth which interfered
with tlie movement of the misplaced one into proper
position. This use of the file to provide space seems
to have been a common practice at that period and later.
He seldom re-
sorted to the extraction of teeth for regulating purposes, probablv believing
