single-visit bridges provide strength, durability, and
immediate convenience. Ribbond bridges are cost effective
and reliable. Excellent for emergencies, implant
temporization, congenitally missing laterals and patients
who cannot afford conventional lab fabricated bridgework.

If clearance permits, a bridge
can be made without preparation of the abutments. If there
is not adequate space, shallow preparations might be
necessary. The following shows the construction of a
long-term bridge framework. For provisional bridges one
layer of Ribbond can be used.
Prepare teeth for bonding and place a
thin layer of composite on the teeth.
Wet the Ribbond with bonding resin and
place it spanning from one abutment to the other. Place the
Ribbond so that it will be under the incisal edge of the
pontic. Remove excess composite and cure.
Place a thin layer of composite
lingual to the first piece of Ribbond in the pontic
section of the Ribbond framework.
Wet a second piece of Ribbond and
place it against the composite in the pontic section of
the framework. Cure.

The second Ribbond layer
attaches over the first composite layer only to
the proximal lingual angles of the teeth adjacent
to the pontic.

This case shows an elderly woman who lost
a mandibular central incisor due to severe periodontal
mobility. A Ribbond splint was made incorporating a
framework to support a pontic for the edentulous space. The
root of the extracted tooth was cut off and the crown was
bonded to the framework. At last check this case was still
in service after seven years.
