full upper and lower rehabilitation with an
improved bite relationship or, at the very least,
bonding composite resin into the severely
worn areas to reinforce the upper and lower
incisal edges. This would protect them
from chipping and prevent further erosion
of the dentin. In either case, a nightguard
was part of the plan.
It was made clear to the patient that
edge reinforcement would address the results
of his bruxism, like the worn and chipped
edges, but not the causes. He was advised
that he could expect the restorations would
need to be resurfaced or replaced from
time to time. The patient opted for edge
reinforcement, and for financial reasons we
had to treat the lower and upper edges at
different times and make his nightguard
after treating both.

The lower edges were treated approximately nine months before the uppers. Fig. 6,
page 31, shows the completed lower edges
when we began the uppers. Conservative
troughs were created in the upper incisal edge
indentations for several reasons. Prepared
enamel would offer better bonding than
unprepared enamel and having a resistance
form for the restorations would provide better
long-term retention. Round end chamfer
diamonds (Komet USA) approximating
the size of each wear area were used to
create preparations (Fig. 7, pg. 31). The
preparations were cleaned with a Microetcher
IIA (Danville Materials) to ensure a clean
surface for bonding (Fig. 8). Fig. 9 shows
the preparations ready to be restored.
K-Etchant Syringe (Kuraray), a 35 percent phosphoric acid etching gel, was applied
to the preparations for 10 seconds and
washed thoroughly. The preparations were
dried, and Clearfi l Universal Bond Quick
(Kuraray) was applied with a 1.5mm fi ne
Microbrush (Microbrush International)
in a rubbing motion. This bonding agent
permeates dentin and enamel in three
seconds because of its new amide monomer.
