Recommended
by many well-known lecturers, the Ribbond endodontic post and core
technique minimizes the chance for root fracture and has the following
advantages.
- Compared
to preformed posts, there is no additional tooth removal after
endodontic treatment. This maintains the natural strength of the
tooth.
- Eliminates
the possibility of root perforation.
- Because
it is made when the Ribbond is in a pliable state, it conforms
to the natural contours and undercuts of the canal and provides
additional mechanical retention.
- There
are no stress concentrations at the tooth-post interface.
- The
Ribbond post and core is passive and highly retentive.
Furthermore,
because Ribbond's translucent fibers take on the color characteristics
of the composite it allows for the natural transmission of light
through teeth and crowns. This provides an exceptionally esthetic
result.
Technique
Other
than the normal endodontic treatment, further shaping is not required
to accommodate the size and shape of a preformed post. The following
is a brief description of the procedure. The Ribbond instruction
manual, included with a purchase, clearly describes this technique
in full detail.
Prepare
the canal for normal dentin bonding. Inject a dual cured moderately
filled composite such as a luting composite into the canal. Use
the special Ribbond post and core instrument to carry the wetted
Ribbond through the luting composite in the canal to the apical
end of the canal.
Apply
composite to the protruding Ribbond ends and roughly form them into
the shape of the core and cure. Build up the core with composite,
cure it and shape it
