| All Porcelain Restorations
In these days of patient awareness and a degree of uncertainty
regarding various metals being placed in the mouth, it is not
surprising that people are concerned with the long term effect
different alloys will produce.
Allergic reactions to base metals, nickel, amalgam etc. are just
a few that are raising question marks and forcing us to consider
suitable alternatives to bonded crowns and bridges.
The following materials are totally metal free, and although
there are certain limitations to each, their strength cannot be
overstated if used and indications are correctly followed.
The
secret behind Procera® AllCeram is its unique combination
of strength and beauty. Over the last few years, new technology
has given dental porcelain better properties. Until now,
however porcelain coated ceramic copings have been neither strong
enough, nor durable enough for widespread use. Procera® AllCeram
is a coping made of extremely dense-sintered aluminium oxide.
The coping is produced in an industrial process known as Procera®,
which ensures optimal fit, high strength, non-porosity and has
the ability to transmit light without being transparent.
Due to the strength of the core material, Procera® AllCeram
can be recommended anywhere in the mouth.
Scanning * Design * Production

The design of Procera® AllCeram coping is developed at the
laboratory using the Procera® Scanner and the data collected
is sent to Sweden for the construction of the Procera® coping.
After completing the machining process, the finished coping is
returned to the laboratory for porcelain veneering of the restoration.
Veneering: Porcelain is built up on the Procera® coping

Cementing: The Procera® manufacturing process yields
a uniform space between crown and tooth. This gives an optimal
fit to the tooths shape and enables the construction to
be properly seated while providing enough space for cement.
The restoration is cemented with the material of your choice.
i.e. zinc phosphate, glass ionomer or a dual cure bond. (avoid
any cements with post set expansion)

Techceram
all-ceramic restorations offer natural looking aesthetics for
the most discerning of patients. The coloured, translucent
base layer provides a natural background allowing the technician
to re-create the depth of colour and translucency present in natural
teeth. Techceram combines FLAME SPRAY TECHNOLOGY with Vita
Alpha porcelain, which can be used either with the traditional
or the new 3D shading system to provide optimal aesthetics. Once
the coping has been fabricated the veneering technique is similar
to that of Procera®.
Likewise the cementation of Techceram is identical to that of
Procera®.
Cerpress SL
Experience the aesthetics of a new generation of pressable ceramics
that can be used for crowns, veneers or inlays. Cerpress
SL is based on two-phase glass ceramic Lucite crystals embedded
in a glass matrix. In addition to the absorption, reflection
and transmission of light, which primarily determine colour and
transparency, light refraction plays a vital role in the perfect
imitation of a tooth. The crystal size and distribution
of Cerpress SL ceramics is very similar to the morphology and
microstructure of natural dentition, thereby closely imitating
the optical effects. Sensation SL low fusing porcelain is
layered on the Cerpress coping due to the high content of Lucite
and small crystal size provides increased strength and superior
light reflection qualities. Fluorescence is a major characteristic
in creating a natural appearance.
Sensation SL has the perfect balance of fluorescent elements,
which enables the restoration to duplicate natural dentition in
all lighting conditions. Sensation SL is wear compatible
with natural dentition, meaning it will not abrade the opposing
teeth, as do most high fusing porcelains. It also offers
excellent chair side polishablity.
Sinfony
Sinfony
offers a concept for easy reproduction of the complete VITA classic
colour system. Using the exactly co-ordinated 16 opaque and dentine
materials allowing brilliant shade reproduction. A good
balance of transparency and opacity ensures exact shade reproduction
even in thin veneers. The enamel and transparent materials
are ideal for customising ceramic like restorations with natural
fluorescence and opalescence, creating a fascinating vitality
and brilliance. Sinfony has high plaque resistance, impressive
physical properties, compressive and flexural strength, and impact
and abrasion resistance and water absorption, properties, which
justify calling SINFONY a new type of composite technology.
Consequently, the range of indications is wide
SINFONY is a material for a large number of indications:
Fixed crowns, telescopical and conical crowns, external attachments,
bridges, adhesive bridges, implant superstructures, veneers, inlays
and onlays, long-term temporary restorations and the customisation
of artificial teeth made of acrylic.
