HISTORY OF DENTAL SUEGERY 385

Dr. Goslee says: '"I have made an effort to present tlie subject matter in a
practical and concise form, and in a systematic and sequential order ; heretofore
there has been a lack of co-ordination of thought, and co-operation of effort
such as would result in a practical classification of requirements, methods and
results, and special care lias been given to the various methods which are rec-
ognized as possessing merit and practicability.
''The practical introdi;ction of artificial substitutes for the natural crowns
of teeth, and the ultimate development of crown and bridge-work, is purely the
product of the last half of the nineteenth century, and must be placed to the
credit of American dentistry."
Dr. Goslee gives tlie technic, with illustrations, of the following crowns:
Brewster, Brown, Buttner, Davis, Fellowship, Foster, Gates, Bonwill, How,
Howland-Perry, Logan, Mack, Owens, Richmond, Sanger, Spaulding, Webb,
Weston, and also his own special porcelain method.
His book also contains the teclmic and illustrations of very many varieties
of fixed and removable bridge-work, with a cliapter of his methods on porce-
lain bridge-work, wliich he considers the ideal type of prosthesis.
In the seventli edition of the \\ ork of Dr. George Evans can be found tlie
teclmic, with illustrations, of other crowns than tliose previously mentioned.
viz. : Baldwin, Bonwill, Chuepin, Evans, Farrar, Fillebrown, HoUingswortb,
Kirk, Leech, Litch, I'arker, Parr, Patrick, Perry, Rynear, Stowell, VanWoert
and White.
In 1873 Dr. J. P>. Beers patented his gold cap-crown, all of metal.
In connection with crowns and bridge-work mention should be made of
removable or replaceable teeth-facings, such as the Roach, Wedgelock,
Dwight, Mason and Steele, which have specially prepared backings which are
soldered into the bridge, and then when it is all finished the facings are ce-
mented in place. Thus all liability of injuring by heat is entirely eliminated.
The Steele is the most popular of any mentioned.
Among the patented, manufactured, and special attachments for remov-
able bridge-work are the Roach, Griswold, Condit, Morgan, Kelly, Bryant and
Fossil me.
'J he Taggart method, recently patented, of casting gold inlays to be used
as attachments for bridge-work, and also for casting bridges and partial
jilates, is desirable in many cases. The technic can be found in the second edi-
tion of Dr. Goslee's work.
Ancient bridge-work was fastened to natural teeth with ligatures, or clasjis
of metal, and was quite crude, hut in its evolution it lias absorbed from every
available source whatever would broaden its science and perfect its art, and the
