positions, and teeth filled in this manner are as.
closely knuckled up a day or two after the opera-
tion as any other teeth in the mouth. It is A-ery
nice to be able to separate these teeth so widely
that the whole of the surface of the filling can be
clearly seen during the trimming and polishing.
It is very convenient to be able to build out to
such an extent that free use may be made of
sandpaper and cuttle-fish discs in trimming and
smoothing the filling, and the production of a
perfectly smooth, polished, mirror -like surface,
that will not reveal even a hair-like scratch
under magnifying-glass examination, is the highest
expression of dental art and excellence ; but when
the various difficulties that militate against the
accomplishment of this result are considered, and
the risk of producing either insufficient or plus con-
tour is realised, it becomes a question whether the
filling of bicuspids and molars, without previous
separation, is not, as a general rule, the more
practical and useful method.
