prevents fracture failures in dental composites and acrylics. Ribbond
prostheses are strong and maintain their strength with continued
use. They are tough and durable. Ribbond's unique combination of
ultra-high strength fibers, enhanced bondability and patented cross-link
lock-stitch leno weave makes the strength and fracture toughness
of Ribbond reinforced prostheses unsurpassed by other fiber reinforcements.
Ultra-high strength fibers
Ribbond is made from the same ultra-high molecular weight polyethylene
fibers used to make bulletproof vests. These fibers far exceed the
breaking point of fiberglass and are so tough that specially made
scissors are required to cut them. Unlike Kevlar, Ribbond's fibers
absorb less moisture than the dental resins
Patented Leno Weave
The key to Ribbond's success (and what distinguishes Ribbond from
the other fiber reinforcements) is its patented leno weave. Designed
with a lock-stitch feature that effectively transfers forces throughout
the weave without stress transfer back into the resin, Ribbond's
weave also provides excellent manageability characteristics.
virtually no memory, Ribbond adapts to the contours of the teeth
and dental arch. For example; when making a periodontal splint,
Ribbond tucks in interproximally without rebounding. In addition,
unlike loosely braided or bundles of unidirectional fibers, Ribbond
does not spread or fall apart when manipulated.
fiber reinforced resin structures derive their strength primarily
from making laminates, high manageability and lack of memory is
essential for close and accurate layering of the fibers. Inaccurate
fiber placement results in voids or excessive composite on the tensile
side of the fibers that will be prone to fracturing.
Ribbond's Patented Cross-Link Lock-Stitch Leno Weave.
- Adaptable and Manageable
- Does not unravel when cut or manipulated
- Reinforces multi-directionally
- Durable & impact absorbent
- Transfers stresses efficiently throughout the fiber network
Ribbond bonds to any composite system. You choose the composite
Magnified 110,000 time, SEM's demonstrate complete incorporation
of the resin to Ribbond's fibers (note lack of voids). Forces within
the resin are easily transferred to the fibers insuring that the
Ribbond is an integral strength member of the prostheses.
Ribbond's fibers are the standard in biocompatibility. The same
material is also used in the construction of artificial hip and
knee joints. Unlike fiberglass, if at anytime the Ribbond is cut
into with a rotary instrument, the resultant particles and exposed
fibers will not be a biocompatibility risk to the patient.
Ribbond is translucent, practically colorless and disappears within
the composite or acrylic without show-through. Not only does Ribbond
offer excellent esthetics, its translucency also allows the use
of light cured composites.
The unique combination of strength, esthetics and bondability allows
Ribbond to be used for many different applications. Ribbond bonds
to both composite and acrylic giving you a material with multiple
