preparation. Obtain mesial and distal
reduction with a fine tapered diamond
bur with minimal buccal and palatal
reduction that is just sufficient to allow
the operator to place the crown. It is
tempting not to effect any distal
reduction if there is no erupted second
permanent molar but remember it is
important not to change the proportions
of the tooth or create an overhang that
will impede second molar eruption.504H
Fig. 9.44 Stainless-steel crown is tried in
and fit determined. This crown will now
need to be contoured and smoothed
around the margins so that they fit evenly
1 mm below gingival level around the
whole periphery. It is important that the
crown has a good contact point mesially.
Contour the tooth with the correct pliers.505H
Fig. 9.45 Glass ionomer cement is
placed in the crown, and overfilled to
prevent voids forming under the crown.
Excess cement is removed with cotton
wool rolls and hand instruments, and the
interstitial area cleared with dental floss.
