Overview
 |
 |
|
An absolutely tension free fit: This friction fit system offers the dentist and the dental
technician entirely new options for the preparation and
restoration of telescopic and metal-metal situations. The long
service life and the simple, time saving processing render this
friction fit system a comfortable solution for the patient.
These advantages have contributed to more than 25,000 cases
allowing soft integration and removal of the denture. The
principal of the FGP resin is that the metal on metal telescopic
cases will now be replaced by a metal on resin fit. The metal on
resin fit offers the benefit of a considerably more coefficient
of friction than the one of a pure metal fit. Consequently,
increased resistance to wear and an extended service life are
obtained.

| For this comparison between a classical metal
fit and an FGP fit, 21,000 integration and removal processes
were simulated. This corresponds to a wear period of
approximately 20 years. |

A direct solution rather than extended waiting times |
 |
 |
| The FGP system by bredent offers optimum and
individual friction when preparing new conical and
telescopic crowns. |
The simple use during the restoration of the
friction of telescopic work is the solution for the
dentist and the patient. |

|
Why FGP Metal to Resin friction fit
|
 |
 |
| The excellent sliding properties of FGP resin ensure
gentle, implant protection integration and removal of
the supraconstructions. |
Even very small tensions in the low cost and
biocompatible, single piece casting process are
perfectly compensated. |
|
 |
 |
| The high resistance to abrasion and non-tilting
integrating and removing of the supraconstruction
provide the patient with a high comfort of wear and
simple handling of the denture. |
The friction with FGP resin that will remain stable
over many years guarantees the patients’ happiness and
satisfaction. |

INSTRUCTIONS FOR USE
|
|
FGP FRICTION FIT SYSTEM |
| |
| Before using this product, please read and follow these
instructions carefully. |
| |
|
1. Indication Range
|
| The Friction Fit System (FGP) represents a reliable possibility
to achieve permanent friction for newly produced dental appliances
or in case of lost metal fit. The friction acrylic allows uniform
friction which can be individually adjusted depending on the degree
of adhesion. Telescoping and conical crowns, intra- and
extra-coronal attachments but also Ceka anchors can be reactivated
with this system. Additionally, FGP offers the possibility of
producing secondary elements of telescopic and conical as well as
CoCr supply according tot he less expensive single-piece casting
technique. |
| |
|
2. Processing
|
|
2.1 New production of a telescopic or conical supply in the single-piece casting technique.
|
| Produce the primary elements as usual. Produce a coping from
thermo-forming foil or immersion wax with a thickness of at least
0.2 mm. which is used as a spacer for the FGP acrylic. Cut off this
coping approx. 1 mm. above the cervical margin so that the cervical
margin of the secondary element can be finished thinly later on.
Then duplicate the model with the primary elements. The chrome
cobalt structure and the secondary elements are modelled onto the
investment material model. After casting, finish and polish the CoCr
frame. If the secondary elements are to be veneered with
heat-polymerizing resin, this work needs to be carried out prior to
the FGP relining. The FGP acrylic will not resist these
temperatures. Then the actual FGP relining work can be started |
| |
|
2.1.1 Preparation of the object
|
| Blast the surface onto which FGP acrylic has been applied.
Please use blasting nozzles for manual sandblasting. Blast with 50
mµ aluminum oxide at 4-6 bar (units with automatic blasting material
circulation are not suitable due to the contamination of the
blasting material; they contaminate the metal surface so that the
adhesion of the FGP bonding agent and the acrylic is no longer
ensured). Blasting material residues are removed from the blasted
metal surface using oil-free compressed air or a clean, dry brush.
Then the FGP Bonding Agent is thinly applied using a clean brush and
dried for approximately 3 to 5 minutes. The Bonding Agent is
exclusively intended for the special FGP metal fit. |
| |
|
2.1.2 Mixing
|
| Mix the acrylic components A & B in the ratio 1:1 and stir the
acrylic material without the formation of bubbles. The acrylic
components A & B harden 180 seconds after the beginning of the
stirring process. Pour the material into the secondary elements;
pour slightly more material into the occlusal area so that the
acrylic will flow without forming any bubbles. In order to control t
he friction FGP Insulating Agent can be applied onto the primary
element. The more insulating agent is applied, t he lower the
friction will be. The acrylic hardens after approximately 420
seconds. Any insulating residues must be removed from the denture by
holding it under running water for a short time. The insulating
agent is water-soluble. |
| |
|
2.2 Repair of a worn-out metal-to-metal fit
|
First, grind the surface to be relined with an
aluminum-oxide-bound stone or a new diamond so that a space of at
least 0.2 mm. is obtained. Then continue as described under item
2.1.1. Before starting with item 2.1.2., the dentist has to remove
plaque and saliva from the primary elements in the patient's mouth
and apply Vaseline, if required. By applying, Vaseline the layer
thickness can be increased (the thicker the layer, the lower the
friction!). The object which has been filled with acrylic material
is placed onto the primary elements and pressed onto them manually.
The patient should exert slight masticatory pressure for precise
adjustment. Acrylic material that has flown over the cervical margin
must be removed. In case of a low gingiva line, a retraction ring
must be inserted. After approximately 4 minutes the denture should
be removed from the primary elements and placed on aga. The acrylic
material has hardened after 7 minutes; the impression can now be
removed and the margins can be trimmed. The manufacturer recommends
that you prepare a model of the oral situation first and to check
undercuts.
Please note: If undercuts at primary elements - which are covered by
the outer telescope - are not noticed, it is no longer possible to
remove the denture; therefore it is necessary to block out such
spots! In the case of Cover Denture remove the denture acrylic in
the vestibulary area in the area of the secondary elements to be
relined. Only this way is it possible to remove acrylic material
that has flown over in the cervical area. If it is not removed and
it hardens, problems may result when removing the denture. |
| |
|
2.3 Alternatively:
|
| The secondary elements can be relined on an exact model made of
superhard stone, model resin or on milled metal dies. For this
purpose an individual tray must be produced. If the friction that is
obtained in this way is not sufficient, relining must be repeated in
the mouth using a minimum quantity of FGP Acrylic. The components A
& B are processed as described under item 2.1.2. |
| |
|
3. Safety Recommendations and Hazard Warnings

| |
|
5. Sources of error and how to eliminate them
|
Acrylic hardens too quickly: Temperature of the secondary
element is too high during pouring in the acrylic or the acrylic was
too warn. Repeat entire work process.
Bubbles in the acrylic after removal: Simply mix a few drops of
acrylic, pour in and place onto the insulated die. |
