CONSTRUCTION AND I'LACING OF PORCELAIN INLAY 311

with light pressure. This will be about the consistency of thin
cream. The cement should be thoroughly and rapidlj^ spatulated
and when the "stick" is felt under the spatula it should be ap-
plied to the cavity and the surface of the inlay which is immediate-
ly placed. Use a non-corrosive spatula, preferably bone or agate.
Apply to the cavity with a flattened orangewood stick. Press in-
lay to position with a stick of orangewood using gentle pressure,
gently tapping the end of stick with the knuckle of the forefinger,
or blows of equally cushioned nature.
In labial and buccal fillings (Class Five) the inlay should re-
ceive gentle pressure for five or ten minutes. In proximal (Classes
Three and Four) the filling should be gentlj^ wedged against the
proximating tooth or tightly ligatured to position and so left for
some hours.
The Finishing should be left till another sitting. If the building
has been well done there will be little to do. All overhanging mar-
gins should be dressed down with fine stones and disks and the
surface polished with small Arkansas stones, using a light hand
and keeping the stones well watered.
