Caution: Federal law restricts this device to
sale by or on the order of a dentist.
We urge the use of Hygenic
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
1.5 mm of sound tooth structure all around the
circumference of the preparation, apical to the
core, for desired ferrule effect ( ( F F i i g g . . 0 0 1 1 ) ) . *If that
amount of tooth structure is not available, it
should be created by periodontal crown length-
ening and/or orthodontic extrusion.*
2. Use a radiograph to determine the appropriate
diameter and depth of the planned post space
preparation. Keep in mind that sufficient root wall
thickness must be maintained (1 mm minimum)*
to prevent perforation or weakening of root walls,
and at least 4 - 5 mm of gutta percha must be left
intact to protect the apical seal.
3. Remove gutta percha to preplanned depth with
UX ™
® Rubber Dam with
a Gates-Glidden drill, Peeso reamer and/or hot
instrument. Radiographic verification is recom-
mended. If the canal has been obturated with a
silver cone, remove it and reseal (obturate) with
Hygenic gutta percha before preparing the post
space.
4. To begin creating the post space, select the
ParaPost Taper Lux Drill diameter which corre-
sponds to the
used in Step 3. (See "Approximate Diameter
Comparisons" chart, F F i i g g . . A A ). To help maintain
the preplanned depth of the preparation,
ParaPost Taper Lux Drills have been pre-
marked to identify depths of 7, 9 and 11 mm from
the apical end of the drill.
ParaPost Taper Lux Drills can be used either
manually with the Universal Hand Driver or with
a slow-speed contra-angle. When a contra-
angle is used, the drill must be kept in continu-
ous clockwise rotation until it has been com-
pletely removed from the tooth. This will mini-
mize the risk of the drill seizing in the post space.
Remove all weakened or unsupported tooth
structure. Remove any tooth debris from canal
by irrigating post space with water spray.
