BISCO's
patented U.M. Fiber Posts are constructed from unidirectional,
pre-tensed fibers, bound in an epoxy resin matrix. This
design produces a post with flexural strength exceeding
that of metal posts but with a modulus of elasticity very
close to that of dentin. The low modulus dissipates stress
rather than transferring and concentrating stress, as
with cast or pre-fabricated metal posts. Clinical trials
on Fiber Posts demonstrate a success rate of 99.9% at
3-7 years.1
Available in black or white, BISCO's Fiber Posts are intimately
bonded to the tooth structure and core composite, while
the passive taper respects root morphology and conserves
tooth structure.

CLINICAL PROCEDURE
|
The
tooth has been endodontically treated and filled with
gutta-percha. The remaining tooth structure must be prepared
according to conventional principles.
1. Selection of post size. The posts and drills
are labeled using the ISO number that matches conventional
endodontic files and reamers. Drills are color-coded and
posts are marked with rings for ease of identification
as follows:
ISO 100 |
Drill:
Post:
|
Yellow
2 rings
|
| ISO 120 |
Drill:
Post:
|
Blue
3 rings
|
| ISO 140 |

|
| 2. Canal
Preparation. |
A. General rules
should be followed for length of root canal preparation:
|
- The post length
must equal the length of the clinical crown.
- The post should
be 2/3 to 3/4 the length of the root.
- A minimum of
3-5 mm of gutta-percha should remain at the apex.
- Proper isolation
must be used.
|
B. Remove gutta-percha
with a #1 or #2 Peeso Reamer, #3 Gates Glidden or
a heated endodontic plugger.
C. Select the drill size and post size according to
the ISO number that matches the endodontic files and
reamers previously used.
D. Shaping the canal:
(1)
Using the ISO 70 drill (green) provided, place
a pilot hole to the desired length. Sodium hypochlorite
may be used in the canal as a lubricant, coolant
and cleanser with the drill. This instrument
determines the final depth to which the post
will be placed and serves to guide the final
preparation with the subsequent drills.
(2) A rubber stopper on the shaft of the drill
should be used as a guide for the length of
preparation with radiographic verification.
Assure the drill is always positioned in gutta-percha.

(3) Remove debris
from canal with a water spray, followed by air drying.
|
E. Final canal
preparation:
|
|
|
0 |
|
(2) The final
canal preparation allows sufficient space for the
post and 30 microns around the post for bonding
materials.
|
| 3. Post
Length Adjustment. |
A.
Try-in the post and determine the coronal length
of the post according to the occlusion and final
restoration.
B. Remove the post from the root canal and cut
with a diamond bur or diamond disc.
(WARNING: Never use pliers to cut the post since
the pressure can destroy the structure of the
post.) |

|
| 4. Post
Cementation. |
A. Post Space
Preparation:
|
(1) Apply UNI-ETCH®*
(32% H3PO4) for 15 seconds and rinse with water.
(2) Blot the canal dry with a large paper point,
leaving the dentin visibly moist.
(3) Apply 2 coats of ALL-BOND® 2* Primers
A and B or ONE-STEP®*.
(4) Blot the canal dry with a paper point. Repeat
with a new paper point until the paper point returns
dry from the canal.
This step is important for removal of any pooled
primers so that there is no interference in complete
seating of the post.
(5) Light-Cure ONE-STEP for 10 seconds with
a small light tip. Light access is crucial.
|
NOTE:
The user must use their own discretion as to whether
light will reach into the canal space. Although ONE-STEP
is very light sensitive, Bisco cannot guarantee success
if the appropriate amount of light has not reached the
adhesive.
|
B. Post** Cementation:
|
(1) Coat the
post with ALL-BOND 2 Primers A and B or with
ONE-STEP and lightly air dry. Light cure
for 10 seconds.
(2) Mix equal amounts of POST CEMENT HI-X™*
base and catalyst into a uniform paste (10-15 seconds).
(3) Fill a CENTRIX AccuDose®* NeedleTubes™* syringe
tip with the cement and inject the cement into the
canal. Start at the apical end of the canal and
withdraw the tip towards the pulp chamber. (As an
alternative, a lentulo spiral or paste filler may
be used to carry the cement into the canal.)
(4) Seat the post into the canal gently and maintain
firm pressure (for 5-10 seconds) once the post is
seated.
(5) As soon as the cement has set, proceed with
the core build-up.
|
**U.M.
ÆSTHETI-PLUS™* cementation must be accomplished with Bisco
POST CEMENT HI-X for radiographic identification.
**U.M. C-POST™* cementation may also be accomplished
with any of the following materials:
BIS-CORE™*, CORE-FLO™*, C&B™* CEMENT, according to
manufacturer's instructions.
*UNI-ETCH, ALL-BOND 2 and ONE-STEP are
registered trademarks of Bisco, INC.
*U.M. ÆSTHETI-PLUS, C-POST, POST CEMENT HI-X, BIS-CORE,
CORE-FLO and C&B CEMENT are trademarks of BISCO, INC.
*AccuDose is a registered trademark of CENTRIX, INC.
*Needle Tubes is a trademark of CENTRIX, INC.
ALTERNATIVE TECHNIQUE: To prevent premature set of
the cement when using ALL-BOND 2, follow directions
above except:
Post Space Preparation STEP 4.A.(3): Apply 2 coats of
Primer B only.
Post Cementation STEP 4.B.(1): Coat the post with Primer
B only. Lightly air dry. |
PRECAUTIONS |
POST
CEMENT HI-X left on the mixing pad may appear not
to set. This is due to oxygen inhibition of the polymerization
process. Rest assured the cement will polymerize (set)
in a normal fashion. The user can confirm this by placing
a mylar strip over the excess cement on the pad; the cement
will set within the setting time specified in the Post
Cement Hi-X Directions for Use.
The use of PRE-BOND is not necessary for the cementation
using POST CEMENT HI-X.
|
| 5.
Final Preparation. Conventional principles of tooth
preparation must be followed for optimal results. |
- Preparation for
final restoration must end on sound tooth structure.
- There must be
1.5 mm of sound tooth structure beyond the core material.
- Positive horizontal
and vertical walls should exist.

Removal. A FIBER POST REMOVAL KIT is available
through Bisco. See FIBER POST REMOVAL TECHNIQUE description
and instructions available with the FIBER POST REMOVAL
KIT. |
STORAGE: Store at room temperature (22°C/72°F). See
individual component labels for specific expiration dates.
CAUTION: Unpolymerized resins may cause skin sensitization
in susceptible persons. In case of contact with the skin,
wash thoroughly with soap and water. Phosphoric acid of
Uni-Etch is a severe eye irritant and tissue irritant.
If accidentally instilled into the eye, flush with copious
amounts of water and seek medical attention immediately.
In case of contact with other tissues, rinse immediately
with plenty of water for several minutes. Injury may result
if Uni-Etch is allowed to remain on the skin or mucosa
for extended periods of time.
