Hi-Rem Prosthetic Post
Easy Removal, Translucent and Radiopaque type "S" glass fiber
endodontic post.
They are composed of type "S" high-strength glass fibers in an epoxy
resin matrix. They are preferably inserted after preparation of the
canal with Prosthetic Drills.
If, for any reason, it is necessary to remove a Hi-Rem Prosthetic Post
from the root canal, Hi-Rem Prosthetic Post has a soft, colored
macro-fiber that allows guided and safe post removal through an
internal reaming procedure (See Removal of Hi-Rem Prosthetic Post)
Sizes and color codes
Hi-Rem Prosthetic Posts (19 mm in length) and Prosthetic Drills, are
available in four sizes, with color codes for a corresponding use:

Indications
Hi-Rem Prosthetic Posts, conical-cylindrical shape, have been
designed to suit all clinical cases and in particular teeth that are
extensively destroyed and very stressed. The available sizes allow all
dental typologies to be treated (Tab. II).

Steps for clinical use
1. Remove all the sealing material until the calculated depth using
endodontic drills such as Gates-Glidden® or Largo® at low speed
(1500-2000 RPM). Minimize removal of canal dentin. At least 3 - 4mm
of the apical seal must remain to guarantee endodontic success.
2. For prosthetic restorations: at least 2 mm of dentin must remain
above the foreseen preparation margin to guarantee the "ferule" effect;
3. Select the post to be used based on the type of tooth and the width
of the canal (Tab. II); the post must be the largest still compatible with
the canal diameter; the portion that enters into the canal must be at
least half of the post total length.
4. Once the post has been chosen, prepare the apical portion of the
canal with Prosthetic Drill, refer to table I.
Prosthetic Drill must be sterilized prior to use.
• Shorten the coronal portion of the post, bringing it to the desired
length. Use only diamond rotating instruments of medium or large
granulometry.
Carry out this operation far from the patient, using gloves, a mask, and
protective goggles.
5. Clean the post by immersing it in pure ethyl alcohol or coating it with
32% phosphoric acid gel for 60 seconds; then wash it with plenty of
water for at least 30 seconds and dry it until it became matt white.
6. As Overfibers post surfaces are particularly rough, silanization
treatments are optional.
7. Hi-Rem Posts can be used with auto-polymerizing or dual-curing
adhesive/cement systems. Choose the preferred adhesive/cement
system and carefully follow the manufacturer's recommendations.
8. Reconstruction of the stump: choose the desired reconstructive
system and carefully follow the manufacturer's recommendations.
Place the composite directly on the external part of the post,
Hi-Rem Prosthetic Post
previously treated with the adhesive system. Do not create empty
spaces. CAUTION: temporary cements or disinfectant substances
containing phenols (e.g. eugenol) previously applied to a tooth can
greatly reduce the bond to the dentin and the strength of resin cements
and composites!
9. After tooth preparation, apply the PROVISIONAL RESTORATION,
avoiding cements or disinfectants that contain phenols (e.g. ZOE
cements).
Removal of Hi-Rem Prosthetic Post
1. Expose the post with a diamond bur to the coronal level until the
colored macro-fiber will be clearly identified at the center of the post.
2. Use a new, thin (0.25 - 0.3mm) Ni-Ti rotating file at medium speed
and drill gently into the macro-fiber with up and down movements.
3. Allow the instrument to penetrate for 1.5 - 2mm and retract it after 3
- 4 seconds to allow the removal of the melted shavings. Avoid
excessive friction heat build-up, but do not use cooling spray.
4. Repeat the procedure until the depth established on the radiograph
is reached. Since the macro-fiber is very soft, the instrument is guided
towards the post tip by the harder walls of the post, without ever
deviating from the central axis. During this phase, the operator can
clearly feel that the instrument is conducted through the post by the
macro-fiber, thereby assuring a sense of certainty.
5. After drilling through the macro-fiber, a canalized post is obtained:
grind out the internal walls of the post with new, typical Gates-Glid-
den®, Largo®, or Peeso® reamers, until cement or dentin is reached.
Beware the excessive friction heat!
6. Remove the remaining cement and other debris using proper
ultrasonic tips and make a radiograph control to be sure the old
cement is utterly gone. Now the removal of the post can be said to be
finished: rapidly, safely, without sacrificing healthy dental tissue.
7. Proceed with the conventional endodontic treatment followed by the
proper restorative practices.
