Preat Perma Fiber is a PMMA impregnated e-glass fiber which is technique sensitive. We now recommend the use of our 2nd Geneartion eFiber material.
Perma Fiber and Mesh can be used on crowns and bridges as well as removable partial dentures and full dentures.

Perma Fiber & Mesh FAQ
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 ceramic.
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.
