What is it?
|
Perma Fiber and Mesh are revolutionary
E-glass fibers. Each strand of this e-glass is computer impregnated
with a PMMA (porous polymer) and silane coupler that allows dissoloution
bonding to all acrylic and composites (FIG
1). |
| Adequate
adhesion of the fibers to the polymer matrix is the most important factor
for strength. Bonding
requires
proper impregnation of the fibers. With
materials that bond, you have
the ability to cut and polish to a smooth surface,
eliminating tissue irritation.
Grinding and polishing may be either in laboratory or chairside.
Metal wire
& mesh do NOT reinforce polymers.
Polyethylene (even with plasma) does NOT bond. |

Materials that bond result in a
1000% strength increase over non-reinforced materials.
This is due to the elimination of the gap between
reinforcement material and acrylic resin.
Polyethylene fibers, metal, and kevlar
can not properly bond to acrylic resin.
The chart (FIG 2) shows a study by P.K. Vallittu published in the May issue of Journal of
Prosthodontics regarding fatigue resistance.

Fiber and Mesh allows the user to finish, polish, grind, reduce, and adjust
the prosthesis.
This allows for a smooth finish, eliminating a rough surface
(FIG 3-4) that will irritate the
patient. This smooth finish also allows for superior hygiene, as bacteria adheres
poorly to smooth surfaces, such as the finished prosthesis using Preat Perma Fiber and
Mesh. |

| Fiber and mesh are a scientifically
proven solution for composite and acrylic restorations.
Perma Fiber and Mesh have over 10 years of
research and 600 clinical cases in collaboration
with both foreign and domestic universities. Cases
have been published in over 60 different publications. |
When to use Fiber &
Mesh?
- Repair
of Full and Partial Dentures
-
Reinforcement or Strengthening of New Full or Partial Dentures
-
Reinforcement of Temporary or Provisional Bridges
-
"Maryland" Type Bridges
-
"Flippers" or Other Removable Prosthesis
- Intra
Oral Splinting
- Reinforcing
the "female" area of an overdenture attachment
- Thin palate
maxillary dentures
- And many, many
more!
|
Why to use
reinforcement?
- Prevent
Stress Cracks from beginning
- Fracture
is Caused by Flexural Fatigue
- FRC
(Fiber Reinforced Composites) increase fatigue resistance
- Esthetics--the
fibers are transluscent
- Happy
patients!
What are the advantages of Preat Perma Fiber and Mesh?
- Strength
(glass fibers and bonding!)
- Easy to grind and finish...stop
breakage where it starts
- Dissolution bonding
- Works with all monomers
- Two types of materials--mesh and
fiber
- Easy to handle; no special tools
needed--Improved lab
productivity and products
- Great esthetics....materials are
translucent when wetted
- Chairside technique can be
applied to limit the number of patient visits
|
Where to use it?
The three major factors of reinforcement are:
-
Position or Placement
-
Bonding
-
Direction and Bulk
Preat Perma Fiber
provides strength and rigidity, while the mesh provides toughness to acrylic resin.
When space is available, the use of Fiber is recommended. Mesh is to be used in very
thin areas of acrylic resin, or when the direction of forces are unknown.
|
|
Position and Placement
Place
the fiber in the weakest area. On the
tension side during mastication, and on the
exterior of the prosthesis - not buried
(FIG 1-2). For repairs, place
reinforcement 90° to the fracture. The "I
Bar" design is the strongest.
|
|
|
|
| Fiber & Mesh--can incorporate very
close to breaking point due to ability to grind, polish, finish. |
Other reinforcement--must be buried
deep in prosthesis due to inability to grind, polish, and finish. |

Direction and Bulk
Unidirectional are stronger, especially when the
direction of the highest stress is known. |
