Staub Development

Recently a new technology was introduced to the United States that will
revolutionize the way our industry restores teeth. The Staub™ Cranial
system is a simple but effective way to locate natural tooth position.
Restorations are aligned based on cranial reference points and designed
on the basis of mathematical calculations. This new approach challenges
the use of average values or practitioner judgment and will set new
standards both clinically and in the lab. There are times when restorative
appliances have little if any resemblance to the natural dentition and have
not been manufactured to be patient specific. This is especially true for
denture wearers who commonly have two or three sets; one for looks, one
for eating, etc. Dental technicians seldom see the patient and are left to
manufacture what they believe a restoration should look like. The position,
function, shape, and inclination are left to artistic discretion, not exact
calculation. The premise of Staub is that every person has one and only
one correct occlusal position. The question raised by this premise is: Are
we capable of calculating exact tooth placement?
Master technician* Karl Heinz Staub (Neu- Ulm, Germany) answered this
question when he spent 25 years researching and developing mathematical
theorems that determine the exact position of the natural dentition. During
his research on more than 5500 different models, K.H. Staub was able to
demonstrate constant parameters in both the maxilla and mandible which
had been unknown in dentistry until now. The results of this research led
to the development of the Staub™Cranial System. The article below shows
the results of a study done by Freiburg University in 2003:

The Freiburg University Hospital Study:

Reconstruction of tooth positions using the Staub Cranial System Aim: The
Staub Cranial System, developed by master dental technician Karl-Heinz
Staub (Neu-Ulm, Germany), is based on defined anatomical reference
points which should be present in every jaw model with unalterable
positions. The aim of the study was to check the ability of the Staub
method to reconstruct the former position of lost teeth in an edentulous jaw.
Materials and methods: Two maxillary alginate impressions were taken and
fi lled with hard plaster in each of 20 completely dentulous subjects with no
history of orthodontic treatment. All teeth were erased with a plaster cutter
in one of the two models made for each participant in the study. Master
dental technician Staub, who was unaware of the baseline situation, drew
up a list of tooth positions for each of the 20 edentulous models. The
spaces were subsequently determined between the mesiobuccal cusp tips
of replacement teeth 16 and 26, between the canine tips of replacement
teeth 13 and 23, and between the cutting edge of replacement tooth 11
and the highest point of the gingival margin. Measurements were made
using the principle of stripe projection, a non-contact method of recording
surface contours, and using specially developed software (Topoline;
Institute of Laser Technology in Medicine and Measurement Technology
at Ulm University, Germany). The 20 control models were measured in
the same way. Then the number of reconstructed models was determined
whose distances measured deviated > 5 % from the mean values of the
distances measured for the 20 control models. Number of deviations of
the distances measured. 95% CL = 95% confidence limits. Discussion:
The results indicate that the Staub method is astonishingly capable of
reconstructing the former position of lost teeth.
