| Cut sufficiently large pieces of Perma
Mesh for crown frames. Use at least 2 layers per frame
(Fig 1). Use a plastic bag to wet the fibers.
Apply at least 1 drop/cm2 of light curing resin to the
Mesh (Fig 2). To wet the fibers in 3
minutes, roll a folded plastic bag back and forth between your fingers. You
can also leave the plastic bag for 10 minutes to wet; remember to keep it
protected from light. |

| Place the Perma Mesh
pieces on top of each other and at a 45 degrees angle across each other
(Fig 3). Push the pillar model and the
Mesh pieces against the silicone

Remove the Perma Mesh carefully from the pillar
and cut out the excess fiber material from
marginal areas (Fig 4). |

| Cut suitable length pieces of
Perma Fiber to make the frame of the bridge. Use
at least one layer of fibers for one pontic, two
layers for 2 pontics etc (Fig 5). Note: use at
least two layers of Perma Fiber in molar region.
Use a light curing resin for wetting. Apply at least 1 drop of resin per
1 cm of fibers. Wet the fibers
for at least 2 minutes, until they are translucent. Bend the fibers
hard to improve wetting (Fig 6). |

| Press the wet fibers
against their intended location, using the
silicone forming aid, with a folded plastic bag as
an option (Fig 7).

with composite and light cure. Refine the margins with rubber
(Fig 8). |

Tip! Fill the empty spaces between the fiber
layers with flow composite to give the structure more stiffness and
strength. |
