In applications such as cuspid
reconstruction, multidirectional
reinforcement can arrest cracks
and prevent their propagation in
the cervical direction. As shown
in literature, dentin pins increase
shear resistance of extensive
composite restorations.
with enough strength to withstand an occlusal challenge,
especially if the restoration is subjected to the same forces
that initiated the original failure.

Conclusion
As oral health providers, we are always looking for
the best treatment techniques for our patients.38 Carefully
combining pins and high-strength polyethylene fibers with
excellent restorative material can improve the long-term
prognosis of a tooth. The results are a successful aesthetic
integration of the restoration-and easy repair, if necessary.
In selected clinical situations, reparation is an advantageous and practical alternative to a replacement and can
significantly increase the lifetime of these restorations.39
Cuspal coverage with direct posterior composite restorations
may represent a valid alternative to conventional indirect
restorations. The data indicates that composite resin is a
technique-sensitive restorative material that can be used
in large preparations, if proper manipulation and isolation
can be maintained.40 This requires an increased attention
to detail, and the main reason for failure over time would
be secondary caries and fractures. ■
