Heraeus’ Pala Laboratory Products Division Launches Two Fracture-Resistant Acrylics

SOUTH BEND, Ind., Dec. 5, 2011 /PRNewswire/ — Heraeus Kulzer, LLC, the
worldwide leader in dental esthetics, announced today that it has added the
high-impact heat-curing Paladon ultra and cold-curing PalaXpress ultra
fracture-resistant acrylics to its Pala line of denture-related products. The
Pala division of Heraeus, which is the inventor of dental acrylics, is
continuing to push the boundaries of prosthetic innovation with these two new
products delivering superior breakage resistance and impact strength.

Denture stability begins with the denture base, particularly for demanding
indications such as implant restorations with their increased masticatory
forces. With Paladon ultra and PalaXpress ultra, technicians can easily and
safely produce esthetically exceptional implant overdentures, combined
restorations, and full or partial dentures.

Paladon ultra: The superior heat-curing acrylic for the highest requirements

Paladon ultra allows implant overdentures and fixed removable dentures to be
manufactured as simply and easily as partial or full dentures. Paladon ultra
exceeds the required standard values for fracture resistance, flexural strength
and modulus of elasticity. This helps to increase the denture’s longevity and
will ensure laboratory, dentist and patient satisfaction. Paladon ultra, which
is certified biocompatible for user and patient (ISO 10993), also exhibits high
color stability. It will be available in shades pink, light pink, dark pink,
light reddish pink, shade 200, pink veined, R50 veined and pink live.

PalaXpress ultra: The universally applicable cold-curing denture acrylic

Cold-curing acrylic PalaXpress ultra offers dental technicians a new class of
denture acrylics that is up to 50 percent more fracture-resistant than other
cold-curing acrylics. Heraeus has created a unique formula that delivers
exceptionally easy and reliable processing along with excellent esthetic
results.

The secret to PalaXpress ultra’s high fracture resistance is a special material
with a unique composition. These additives are highly soluble and form an even
and strong bond with the other components of the powder-liquid system during
polymerization. They stop microfissures, thereby preventing the formation of
fracture points. Heraeus is the first manufacturer to integrate this technology
in cold-curing acrylics.

Dentures made of PalaXpress ultra are extremely durable. The acrylic meets or
exceeds the strict requirements of ISO 20795-1:2008 for fracture resistance,
flexural strength and modulus of elasticity. The result is a highly durable,
stable and yet flexible polymerized material that enhances longevity, minimizes
complementary repairs, and increases laboratory, dentist and patient
satisfaction.

PalaXpress ultra makes the production of high-quality dentures even easier and
more reliable. The powder-liquid system can be processed in the same way as any
other cold-curing acrylic. The fracture resistance and elasticity of PalaXpress
ultra reduce the risk of fracturing during trimming and polishing and provide
additional safety for tricky processes like deflasking. Its special formula
allows powder and liquid to blend perfectly, which gives the dental technician
not only fracture resistance but highly esthetic results with a very even
surface structure. Dental technicians and patients will also appreciate the
standard-compliant color stability of PalaXpress ultra.

As a universal acrylic, PalaXpress ultra can be used for a wide range of
indications and all established methods of fabrication. As a component of the
Pala system, this cold-curing acrylic can be used with Heraeus’ familiar Pala
equipment. For example, PalaXpress ultra is suitable for the casting technique
as well as for the injection method with Palajet. This flexible and versatile
material is also suitable for more than just the standard requirements of
dentures. PalaXpress ultra makes fabrication of implant-overdenture prostheses,
two-part dentures, and cast model-based partial or full dentures or full
dentures both convenient and reliable. The dental technician can even make
constructions with a particularly large number of subcomponents in an easy and
reliable way.

Pala: Fusing art and science to create the world of esthetic dentures.

Heraeus’ Pala Laboratory Products Division has been setting the standard for
prosthetic excellence for over 75 years. With its Mondial® and Mondial® I
denture teeth, Palajet® and Palamat® denture equipment, and acrylics like
Paladon ultra and PalaXpress ultra, Pala enables dental laboratories and
practices to create perfectly matched prosthetic products capable of truly
transforming lives.
