Perma Mesh Hoods

in thin areas of acrylic or over attachments to increase strength and reduce acrylic fracture

Because Perma Mesh is translucent and easy to polish, it may be used in any thin areas to increase strength and toughness without sacrificing esthetics.

In cases where there is thin acrylic, especially over attachment cases, Perma Mesh hoods are indicated.

The hoods may be designed in any shape (flat, concave, etc) to best fit each specific prosthesis. In the following instructions, we are fabricating a concave/bell shaped hood.

Seat the attachment female and spacers over the male attachment. Use Perma Block, or other blockout material, to blockout and create a relieve area 0.5 to 1mm above and around the female attachment.



Every piece of Perma Mesh has been impregnated with PMMA via a silane coupler. Unique to Perma Mesh and eFiber is that these materials form a chemical, as well as mechanical bond, with resins. In order to activate the PMMA in Perma Mesh, make a "slurry" mix of self cure acrylic--mostly monomer, but still some polymer. Cut two pieces of Mesh per reinforcement area and pour this slurry mix on the Mesh. This activates the Polymer inside the Mesh. The Polymer (inside the Mesh) is activated and the Mesh is ready to use when the Mesh turns translucent. If you wish to light cure the Mesh, wet the Mesh with Light CureWetting Agent.


Apply the translucent Mesh around the blocked out attachment. The Mesh is very easy to contour and adapt to the appropriate shape. If you choose to solely reinforce the occlusal area of acrylic, blockout and adapt the Mesh to be flat instead of the dome-shape for attachments.


Cure the wet and adapted Perma Mesh hood. Remove the cured Hood and make any necessary adjustments. The cured Mesh is easy to cut and grind. During acrylic processing, tack the mesh hoods to the ridgelap of the denture teeth. Process acrylic in normal fashion.
