Current developments focus on minimally invasive procedures with less post-operative pain for the patient and faster healing time. Piezo technology has been increasingly finding its way into oral and maxillofacial surgery (OMFS) and implantology for more than a decade.

the handpiece and sets the correct power class automatically. This
significantly lowers the risk for the operator of overloading the
instrument tip.
Equipped for any task
W&H offers a selected range of 24 intelligently created working
instrument tips to provide optimum cover for the wide variety of
tasks dealt with by Surgeons. “For example, the bone saws have
a specially developed patented tooth design which enables bone
block harvesting with low bone loss. We also offer a special saw
that boasts extremely high cutting performance. Many of the
surgical instrument tips developed by W&H are an absolute world
first in the global dental sector and are patented to protect W&H’s
unique expertise in this field,” Mr Jobson said.
The instrument tips have another significant advantage in their
efficient cooling concept. The spray exits near the instrument tip’s
work area thus protecting the instrument from thermo mechanical
material stress. The user benefits from even safer processing and
cooling of the operating field.
Piezomed supports the surgeon’s individual way of working
with three different operating modes: “Power”, “Basic” and
“Smooth”. The operating modes store a variety of performance
characteristics. Equipped with a multi-functional foot control, the
surgical device ensures optimum concentration and freedom for
the user’s hands.
First reports from users
“Many of our customers around the world are already making
excellent use of Piezomed in their practices whilst carrying out
clinical work. It is essential for us to obtain feedback on a medical
and professional level to enable us to verify that our development
aims are being implemented consistently,” Mr Jobson said.
Initial reactions from Dr Mario Kirste MSc, a specialist in
implantology and oral surgery from Frankfurt (Germany) and Dr
Ulrich Furst, a dentist specialising in oral surgery from Attnang-
Puchheim (Austria) are testament to the great relevance of
Piezomed in everyday surgery.
The Piezomed has now been launched in Australia and was
first seen by oral surgeons at the Australian and New Zealand
Association of Oral and Maxillofacial Surgeons (ANZOMS)
Conference and also at the AOS 2013 conference and exhibition
hosted by the Australasian Osseointegration Society in Perth in
late 2013.
Dr Mario Kirste said Piezomed heralded the start of a new age
in the use of piezo technology in dental surgery. “The automatic
instrument detection function is a particular advantage of the new
Piezomed. This not only facilitates operation, but also increases
application safety.”
“Incredible – the new Piezomed cuts through bone like butter.
The innovative, very thin special saw with coolant which exits at
the operating point leaves nothing to be desired in terms of cutting
speed, cooling of the saw blade and the hard tissue to be treated,”
Dr. Ulrich Furst added.

Minimally invasive, maximally
effective oral surgery
Current developments focus on minimally invasive procedures
with less post-operative pain for the patient and faster healing
time. Piezo technology has increasingly been finding its way into
oral and maxillofacial surgery (OMFS) and implantology for more
than a decade.
W&H Territory Manager, Chris Jobson, said maximum
surgical precision and gentler treatment for the patient are just
some of the advantages of this leading-edge drive technology.
“Our product development has a clear aim: to consistently
fulfil the many different needs of the patients and also to
satisfy the users’ requirements. The new Piezomed minimises
the invasiveness of surgical treatments. Thanks to automatic
instrument tip detection and unique instrument tip design, the
concept of ‘safe working’ takes on a completely new meaning for
the user.”
A new dimension in bone
surgery
The new surgical instrument
from W&H employs state-
of-the-art ultrasound
technology. High-frequency
micro-vibrations enable
high-precision incisions,
while the so-called
“cavitation effect” helps
to maintain good visibility
in the operative field by
dispersing a coolant fluid
as an aerosol that causes
the blood to essentially
be washed away.
Furthermore the
cavitation effect
will bring about
h a e m o s t a s i s ,
which results in a
bloodless surgery
and an excellent
view of the treatment
area.
In addition, W&H
offers maximum safety
during operation with its
patented automatic instrument
tip detection. Piezomed detects the
instrument tip during insertion into
