K' volution - Dental Kiefer

DENTAL KIEFER
Since 1984 engaged in innovation, development and tuition of dental
technology.
We offer a cohesive system of precisely adapted components of our highest
quality from the impression tray to the face bow transfer, as well as from 3
different ways for a high precision dental model to the anatomically “bio-precise”
articulation … and much more.
The following information will give you an overview about the diversity of our
products.
The different themes are clearly delineated to facilitate access by clicking on the
desired subject.
For further in-depth studies of the technologies and applications of our products
we organize regularly courses at our fully equipped laboratory in the northern of
the Alsace, France.

Useful tips for the preparation
We had an idea how the dental preparation might be facilitated-but
unfortunately, somebody else has been decidedly faster.
In the interest to spread knowledge we feel, nevertheless, compelled to
acquaint all possible user with this idea.
Thanking the originators „Brasseler-Komet“ for providing this documentation
to us, we append hereunder some explanations about their technology.
The work on the
patient is
encumbered with
many problems. To
warrant the best
results and to
facilitate our work, it
is the more important
to select the most
suitable products.

The polished guiding pin offers a reliable support during the preparation,
cleanses the part below the preparation‘s border to permit a proper
impression taking and, at the same time, permits to dilate the root of the
tooth.
As actually already requested in 1977 by Professor Martingnoni, Rom, Italy.

And that leads us the problem
of the precise impression
which is considerably
facilitated by the use of this
diamond studded guiding pin.
Which, under normal
circumstances, obviates the
need for coagulation
measures.

High quality plastics molding materials:
one of the bases of our inventions!
stable, disinfectable ( up to 80 ° C ) reusable

Twinvacuation
innovative evacuation – and – pression technique
Our tray is hollowed out. 2 holes at the inner
sides ( molar area) are connected with the
green tube.
Under the handle, a conical injection channel
allows to inject the cleaning liquids, correcting
material, a.s.o.
Specially designed for the
most difficult cases:
Its tube is fixed at the
absorber of the dentists unit

TWIN JECTION

Corrective material only
on the prepared stumps
…..
Common mistakes
…. is the reason that the stumps also by using a
precision model will be lower than the remaining
teeth. The result: --► wrong articulation !
Crowns and bridges will be to high in patients
mouth = doctor has to grind !!
Pre-impression taking after the preparation
contributes to compression of the corrective
materials and results in too small stumps.

are reusable and can
be sterilized !

sturdier than most
metal ones.
The height for two

other impression trays
for only one !
“Spee`sche” curve and closing angle were considered. The sturdy bottom
saves material and enhances stability. Different thickness in front and
backside!

Palate impression
The reusable palate bit is
simply to be put on the
tray – it locks on !
Routinely there is no need for
a palate bit
= no risk of gagging
Where it is, however,
indicated – e.g.
Combinations or Totals

All impression trays‘ sizes are
also available in transparent
material
- i.e. ideal to determine the size
according to the patient‘s
physical requirements.

Single phase

Twin Jection
Twin Jection allows using practically
any material and technique
Or corrective impression taking by external dynamic injection
Double mix

Theory
Hydro, single phase, double mix, or corrective impression
Common mistakes at the corrective impression:
2. Pre-impression taking after the preparation
3. Insufficient clearance = putty touches the gum. During the corrective
impression the putty is pushed against the stump.
If around the stump there is no clearance, how can the corrective
material flow and reproduce the exact image of the preparation ?

Twin Jection:
Technique 1
The injection channel lays
above the teeth occlusion
Theory
We recommend pre-impression prior to the preparation –
providing the space for the corrective material and obviate
cutting later on.
Plus, the putty has enough time to harden.

Twin Jection:
Technique 2
Theory
At the corrective impression with Twin Jection the material
flows under pressure from occlusal along the prepared walls
in the direction of sulcus. Impurities, such as blood, saliva and
air bubbles are pushed out through the elastic gum. As the
injection pistol with the corrective material will immediately be
withdrawn after the injection, the produced pressure will fast
dissipate without any deformation or overpressure of the
impression.

Techniques
4. Also the counter part!
1. Putting the space holder
2. Apply some putty
and allow it to
harden
3. Fill the tray until the rim

The counter

The technique
Following the hardening of
the first impression
– the elastic space holder
will be retracted.

The technique
Opening the injection
channel between teeth
center and main channel

The corrective impression
The same to the counter side
At first we fill the main channel
Applying corrective material
onto the impression –
preparation side

The corrective impression
After the prepared impression has been
put into the patient`s mouth
– Attention ! – the mouth should not be
opened unduly to prevent spasm of the
jaw muscles; which, in turn, might
render insertion of the impression tray
more difficult.
Always insert OK (upper) first then the
UK (lower ).Subsequently the patient
should exert his bite without undue
force.
The unique advantage of our technology relying on external pressure
results in a dynamic flow of the corrective material expelling blood, saliva
and air bubbles through the elastic gum.

The result
Equal distribution of the corrective material – to prevent
differing heights of the stumps in the model.
Quite obvious :
The even
distribution of the
corrective material

Iron rules for successful impressions with
„Twin Jection“
• Selection of the optimal impression tray size is mandatory for the corrective
material – channel must be exactly in the middle of the occlusion
• Pre – impression before the preparation
• Pre – impression to start invariably on the preparation`s side observing
strictly proper alignment – then to close counter
• At the pre – impression it is imperative to leave enough putty around the
stump – approx. 3-4 millimeters and that the same thickness is also above
the preparation`s borders adjoining the gum.
• With more putty applied in the pre – impression phase it may provide a layer
around the impression tray`s border – thus enhancing more stability.
• For single crowns just a hole to the main channel is punched with our
special tool – for several crowns or bridges a linear opening suffices.
• Corrective impression always first to be put in upper jaw – even though the
lower has been prepared. The patient will find the right position with the
lower invariably.
• Putty should preferentially have hard shore quality
• Correcting material should have medium viscosity

The result :
An even distribution
of the corrective
material across the
whole impression.
The only way to
avoid differing
heights of stone
model dies.
Single crowns
Pre – impression before
preparation – followed by opening
the channel using the round hole

Bridge impression
Bridge impression :
- Pre – impression before preparation
- Linear cutting to main channel
That way one recognizes the mounting
angle of the root. A prerequisite for is
transfer to the replacement tooth

Inlay impression
Considerably more
economical than
„Kofferdam“ – the rubber
band for sports.
For the pre – impression
we cut a piece of that
rubber foil.
The transparent impression tray will
be marked where the inlay
preparation will be effected

Inlay impression
The rubber piece is located in
the desired area to create the
occlusal space for the
correcting material.
For the corrective impression we remove
the holder. The gap to the remaining teeth
will ensure an adequate thickness of the
corrective material around the area of
preparation.

The result:
An even distribution of the
corrective material assures
a perfect occlusion.

was of the opinion
that a better basis
prosthetics were
unattainable.

Temporaries with „Twin jection“
A pre – impression with putty will be made
prior to the preparation. The special tool
again serves to open the channel
The external dynamic injection technology serves
ideally also for the production of temporaries
Modern self – mixing resins are used – those
do not react with the „Twin jection“ tray
material.

Temporaries with „Twin Jection“
The result
If for instance, a temporary with an
intermediate part should be made, an
artificial tooth takes its place in
patient`s mouth to permit checking of
the occlusion. Subsequently we take a
pre – impression.
The temporary in the impression – to remove
it one may cut the putty.

Silifix „W“
A metal tray at room temperature
reduces silicon to around 18 ° C. But it
had been taken at 36 ° C !!! Therefore
we use „Silifix“ W – wax based – and
heat it to 36 ° C. At this temperature it
becomes soft and , nevertheless, lead
dead. I.e. there is no danger of
deformation for the impression material
or a recoil effect to it.

Pilot pins in the „pilot

Each segment separated by
sawcut is fixed with at least 2
pins. The pins are placed at
random somewhere between the

Again the imression is heated to mouth temperature,
we smoothen the stone surface and reinforce

To avoid gypsum to enter

Preparation of the articulation plate
Several pre – prepared parts are put –
preferentially on „Silifix“ SC – and filled
with „Poly Plus 2000 S“. At the elapse of
approx. one hour the screws will be
loosened, the base plate knocked off
and all be cleaned. That ensures
continuous precision at the articulation.

Should the articulator
imitate „discus

– this is the only way to
imitate anatomical
movements!

Condylus compression test
As soon as the patient exerts
a pressure on that foil – the
„human discus articularis“ is
compressed being pulled by
the muscles. This has an
important influence to the
occlusion and articulation.
For testing the compression of the
human discus articularis we take a
0,15 mm strong foil
