U.M. FIBER POSTS
U.M. ÆSTHETI-PLUS™
U.M. C-POST™
INSTRUCTIONS FOR USE
|
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 |

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.
|
0 |
(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.
|
| 6.
Post 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.
