The technology and materials available to today's restorative dentists offer
various solutions to many complex problems. Missing tooth structure can be
replaced through the use of adhesives or metal-ceramic crowns, and missing teeth
can be replaced with any of a variety of fixed prostheses supported by teeth or
implants. Porcelain-fused-to-metal substructures continue to be a mainstay of
fixed prosthodontics,and polymethyl methacrylate (PMMA) polymer remains the
material of choice for complete denture bases. But we now also have a new
emerging material that is Fiber Reinforced composites (FRC).
Fiber-reinforced materials have highly favorable mechanical
properties, and their strength-to-weight ratios are superior to those of most
alloys. When compared to metals they offer many other advantages as well,
including non-corrosiveness, translucency good bonding properties, and ease of
repair. They also offer the potential for chair side and laboratory fabrication.
Fiber-reinforced composites have potential for use in many applications in
dentistry and
are expected to gain increasing application and popularity in
dentistry.
Fiber-reinforced materials have wide potential for application in a variety
or clinical situations, but the clinician must understand the basic structure of
these materials and the different types available. Awareness of the advantages
and limitations of each type of
FRC enables
the clinician to select the best
FRC material
for each clinical situation.
For splints, crowns, and fixed prosthesis, the clinician must be able to make
FRC tooth
preparations that allow the dental laboratory to place an adequate volume of
FRC to make a
durable, biocompatible framework and prosthesis. The clinician needs to
understand framework design concepts because there is strong evidence that this
is a crucial factor in the success or failure of a fiber-reinforced prosthesis.
Lastly the clinician must be able to perform techniques for luting an indirect
prosthesis or fabricating a direct prosthesis or appliance.
