| What material can I use for luting a Fiber
& Mesh reinforcement frame to the teeth? |
 |
When using a direct method, the Fibers
are attached with adhesives or flow-composites.
When using a indirect method, the fiber frame is dissolved for five minutes
with a suitable resin. After this, luting is done
with either dual or chemically curing composite cements. Ask for detailed
luting instructions. |
| How many adjacent pontics can you build using
Perma Fiber & Mesh reinforcement material? |
|
Three, according to our experience. Naturally one must also take into
consideration other relevant factors such as the adjustment of occlusion and
the antagonistic material. When the prognosis is good, a fiber bridge for
three pontics will last as well as bridges made of other materials. The
bridge’s lifespan is determined by the durability of the crown material and
of the clinical circumstances. We recommend to use at least one fiber bundle
for one pontic, two fiber bundles for two pontics etc. |
| What is the lifespan of Fiber
bridges? |
|
Based on our clinical studies up to date, we can absolutely promise at
least a four years’ lifespan for correctly made fiber works. Based on
laboratory tests we can expect bridges to last even over ten years. |
| How do Perma Fiber
& Mesh differ from other fiber products? |
|
Perma Fiber & Mesh are
the only fiber products that have been
preimpregnated with PMMA polymer on the market. The advantage of having such
preimpregnation is that the complete wetting of the fibers is easier to
achieve even with high viscosity composite resins and acrylic liquid -
powder systems. Also the bonding between the individual silanized glass
fibers and the resin matrix is proven to be strong and stable. For these
reasons, the fibers work effectively with both
acrylic and composite systems. In addition, having part of the resin matrix
composed of PMMA thermoplastic polymer the fiber frame surface is always
partially redissolvable into the composite cement. This property is unique
to PREAT Perma Fiber & Mesh materials and allows
excellent bonding of even indirect bridges to the composite cement and
teeth. |
| Can fibers be attached to ceramics? |
|
A fiber frame can be attached to ceramics just
the same way as composite. The crucial thing is to choose the right
adhesive, one that is meant to be used especially with ceramics. |
| What advantages do fibers offer to the dental
technicians? |
|
These fibers are stronger than metal inside
the acrylic dentures. They can be used for both reinforcing new dentures as
well as repairing broken ones. They provide an aesthetic and cost effective
method for difficult cases (for instance the ones that tend to break often).
Fiber & Mesh technology is a very fast method to
build up all kind of structures, both acrylic and composite. Using
fibers does not require any big investments. In addition, with fiber
know-how one can improve laboratory’s services to dentists. A premium charge
is recommended for all reinforced work. |
