Instructions For Use - Coltene ParaPost Fiber Instrucciones De Uso

ParaPost®Fiber WHITE
One-Office-Visit Technique
Intended Use: Fiber posts are intended to be cemented into the
root canal of a tooth to stabilize and support a restoration.
Caution: Federal law restricts this device to sale by or on
the order of a dentist.
Note: Posts are single use devices and should never be salvaged
for re-use. Structural integrity of the post could be compromised
including microscopic damage which could lead to post fracture.
For illustrations see page 47
We strongly recommend the use of Hygenic
with this procedure.
1. After endodontic therapy has been completed, prepare the
tooth for restoration as if pulp were intact. The preparation
should include at least 1.5mm of sound tooth structure all
around the circumference of the preparation, apical to the
core, for desired ferrule effect (Fig. 01). *If that amount of
tooth structure is not available, it should be created by peri-
odontal crown lengthening and/or orthodontic extrusion.*
2. Use a radiograph to determine the appropriate diameter and
depth of post space preparation. Keep in mind that sufficient
root wall thickness must be maintained (1mm minimum)* to
prevent perforation or weakening of root walls, and at least
4 - 5mm of gutta percha must be left intact to protect the
apical seal.

3. Remove gutta percha to preplanned depth with a Gates-Glid-
den drill, Peeso reamer and/or hot instrument. Radiographic
verification is recommended. If the canal has been obturated
with a silver cone, remove it and reseal with Hygenic gutta
percha before preparing the post space.
4. To begin paralleling the post space, select the Para-Post
Drill diameter which corresponds to the last Gates-Glidden
drill used in Step 3 (Fig. 01). (See "Approximate Diameter
Comparisons" chart, Fig. A). To help maintain the preplanned
depth of the preparation, ParaPost Drills have been pre-
marked to identify depths of 7, 9 and 11mm from the apical
end of the drill.
ParaPost Drills can be used either manually with the Universal
Rubber Dam
®
Hand Driver or with a slow-speed contra- angle (750 - 1,000
RPM). When a contra-angle is used, the drill must be kept in
continuous clockwise rotation until it has been completely
removed from the tooth. This will minimize the risk of the drill
seizing in the post space. Remove all weakened or unsupport-
ed tooth structure. Remove any tooth debris from canal by
irrigating post space with water spray.
5. Sequentially step up to the next larger ParaPost Drill until the
preplanned diameter and depth are achieved (Fig. 02).
6. Use a cylindrical diamond or carbide bur to prepare an
anti-rotational box (Fig. 03).
