To reinforce temporary restorations, begin
by preparing the teeth and making an impression
of the preparations. Pour the impression
with one-third die stone and two-thirds mounting
stone, so it sets quickly. Then ensure that
the matrix fits the model. The fibre can now
be placed across the preparations on the model
and tacked into place with flowable composite.
Once the fibre is positioned, try the matrix back
on to verify clearance between the fibre and
the matrix. If the clearance is acceptable, remove
the matrix and reinforce the fibre by adding
more flowable composite across its length.
Finally, lubricate all areas of the model with petroleum
jelly or ** foil substitute **, keeping all lubricant
off the fibre. Then, load the matrix with the
desired temporary material and seat it over the
preparations and the fibre. After curing, it can
be trimmed and seated in the patient’s mouth
(Figures 17-21).
