The Answers:
Why should I use an articulator?
The articulator provides the dental technician and dentist
a means of communication, analysis, and pre-insertion inspection
of cases for proper fit and function.
Even without patient references, a calibrated articulator will enhance
efficiency and precision when cases move between multiple stations.
However, whenever patient-specific information is provided by the
dentist, it increases the likelihood that the corresponding restoration
will better match the patient. An adjustable, precision articulator
provides the technician with a method of using, interpreting, and
adjusting for the patient specific information provided by the dentist
in a way that maximizes his or her own skills.

Q: Why should I choose the Artex® System?
The Artex System offers many unique benefits that provide production
efficiency and increase control of quality and costs.
In the dental office, the Artex® facebow requires only one
person to lock in the registration with a “flick of the wrist”,
which is then frozen in plaster atop a table that is sent to the
lab for maxillary cast mounting. It’s an easy, efficient,
and secure documentation / transfer system.
Artex articulators are easily and economically calibrated to each
other, providing cast transfer between multiple stations or between
the lab and the dental office with occlusal deviations of less than
10 microns (Hatzi, Millstein, Maya: J Prosthet Dent 2001; 85:236-45).
Magnetic cast retention simplifies the task of moving from one case
to another -- and that translates into time saved.
From average-value to fully-adjustable models, Artex articulators
streamline production and build quality into the process. The Artex
system has a 30 year track record of success in Germany and thousands
of satisfied users in North America.

Q:Which Artex articulator model is best
for me?
To choose a model that best suits you and your dentist clients,
define the needs that you must meet with the articulator. For example,
do your dentists regularly provide lateral and protrusive checkbites,
or patient Bennett Angle and condylar inclination references on
the prescription? If so, then your equipment must be capable of
adjusting the corresponding settings. If not, then perhaps an "average-value"
instrument is called for. Also, for many labs, a designated mounting-unit
makes sense due to the messy plaster work associated with mounting
many casts.
Your Jensen representative can help you to identify other factors
that should narrow down the choice of models to one that makes sense
for your business.

Q: What kind of adjustment settings can
be made on Artex articulators?
The adjustment settings vary by model. The system includes
models with pre-set or adjustable condylar inclination, adjustable
Bennett angles, immediate sideshift (I.S.S.) settings, protrusion
and retrusion indicators for use when incorporating freedom of movement
in all directions for night-guards, for example, and vertical adjustment
capability.

Q: What is the difference in
construction between a non-arcon articulator and an arcon articulator?
In a non-arcon articulator, unlike human anatomy, the components
representing condylar housings are found in the lower member of
the articulator, and the spheres representing condyles are attached
to either end of an axle that is part of the upper member. The upper
arm of a non-arcon articulator can be fully opened without disconnecting
from the lower arm, as with the Artex CN, CT, NK, TK, or TR models.
In an arcon articulator, the condylar housings are part of the
upper member and the condyles are located on either side of the
lower member. This configuration looks more like human anatomy,
and is sometimes preferred when using the instrument to describe
and explain treatment to patients. The upper member of an arcon-type
articulator can disconnect from the lower member when fully opened,
unless the unit employs a centric lock, as does the CP, CR, AP,
or AR arcon models from Jensen. All of the Artex non-arcon and arcon
articulators are adaptable to the Splitex® calibration system,
and models are interchangeable with each.

Q: Is it easier to set Bennett
Angle and condylar inclination adjustments in an arcon or non-arcon
articulator?
It's easier in an arcon, because the condyles and condylar housings
are visible and their movements are easily followed when making
adjustments.

Q: Is it necessary for my
dentist to own a facebow before I can begin using an articulator?
In the ideal situation, your dentist clients will provide you with
as many patient-specific parameters as possible so each restoration
is as customized as it can be. For example, occlusal relationships
can be created and tested in a more lifelike situation when opposing-models
are mounted in an articulator with the patient's maxillary registration
as a guideline. However, if your dentists are not yet providing
facebow registrations, you needn't wait to begin enjoying some benefits
of precision articulators. For example, variables caused by moving
cases from one bench station to the next are reduced, even when
cases are simply mounted in average value, when cases are transferred
between articulators that are calibrated to each other.

Q: Why does the CN
or NK offer an adjustable Bennett Angle, rather than being non-adjustable?
a) Because every person has a Bennett Angle, and it's better to
include it in the restoration than not include it, even if you're
only using an average value.
b) Also, because it's more economical from a production standpoint
for the bases of all the non-arcon articulators to be the same,
and the savings can be passed along. This base also allows you to
use spacers.

Q: What does immediate
sideshift (I.S.S.) provide when incorporated into the restoration?
More freedom of lateral movement in centric.
Back to top
Q: Why doesn't everyone just use a ‘semi-adjustable’
like a CT or CP?
In some cases, additional patient information such as immediate
side-shift (I.S.S.) or retrusive movement from check-bites is provided
by the dentist, and the Artex CR, for example, provides a means
of incorporating those adjustments.

Q: What are the inclinations available for the
incisal tables?
The Artex Carbon series offers a flat, 0° table, and an inclined
table (protrusion 0 - 40°, laterotrusion 0 - 70° (right/left).
The classic Artex system offers a flat table, or 10° and 20°
inserts. There is also a custom individual incisal guidance set
available for you to purchase.
Back to top
Q: When do you need to make an individual incisal
table?
When you want to mimic the patient's incisal guidance and canine
guidance.
Back to top
Q Is this the only way to make an individual table?
No. You can also produce an individual table with self-curing or
light-cured resin by moving the incisal guidance pin around in the
resin, based on where the models guide you. The models should be
mounted with a facebow registration for accuracy.
Back to top
Q Does it make sense for the doctor to make a
check-bite without a facebow registration?
No, because without the correct registration of the patient hinge-axis,
it doesn't provide the correct position for the models.
