A BULLETIN DEALING WITH ISSUES FOR DENTAL HEALTH PROFESSIONALS
Dust Alert
in the Dental Lab
D uring the process of grinding and polishing
work, sand blasting investment material and dry trimming plaster, micro
fine dust particles are produced which conventional filter systems allow
to escape back out into the work environment. Every year more and more
materials are introduced to the market. That is why it is imperative to
have a superior dust extraction system which can handle all different dusts
as well as acrylic fumes. The most dangerous types of materials are cobalt,
beryllium, nickel and quartz. These materials are frequently found used
in the daily routine of most dental laboratories. Once the micro fine dust
gets into the lungs, it can have a fatal effect on the human body resulting
in conditions such as asthma, allergies, poisoning or cancer. Medical studies
in Europe confirm health is endangered with individuals who work in poorly
ventilated workplaces. The study " Pneumoconiosis in Dental Technicians"
by Professor of Medicine Konrad Morgenroth from the University of Ruhr
in Bochum and Dr. Hartmat Korenburger from the Johann Wolfgang Goethe University
in Frankfurt Germany is conclusive evidence that a certain measure
of caution should be exercised. Micro dusts are the finest particles that
can be inhaled without restriction. They reach the deep air ways such as
the alveolar region and cause degenerative pathogenic tissue reaction,
in other words the dreaded Pneumoconiosis. That is why it is so important
to have an extraction system with enormous suction power which captures
the fine dust particles and leaves little chance of them escaping into
the workplace. There are guidelines and recommended limits of concentration
in the air of dust particles. Creating awareness in the Dental Community
of the dangers provides the impetus to explore and research for the best
answers. Some values to look for are two stage filter systems offering
a 99.9 % capture rate. Filter materials that meet ZH/1487 and EN-60335-2-69
designations. The units should be tested for dust category l ( health endangering
dust with MAK values > 0.1 mg/m 3). And finally you should also consider
noise levels of these dust extractors when investigating your options.

B redent's new Biotec Organic Wax System for Pressible
Ceramics was introduced in Cologne at the 2001 International Dental Show
in April.. The Bredent Research Development Team have not only created
an organic wax but a whole system for predictable results in pressible
ceramics. There are five types of Biotec Organic Waxes that have good burnout
characteristics and leave no residual ash behind. There is remarkably minimal
shrinkage to ensure the height of accuracy and homogenous castings. Easily
carved, the shavings can be blown off effortlessly. Next, the new Biotec
Metal Ceramic Pontics MKBL-OG have no collars and exhibit the same characteristics
of the modeling wax. To compliment the system, Isobre-Wax Separator is
made from an organic base which provides accurate separation of waxed patterns.
Even in a dry state it leaves an effective micro fine insulated layer that
ensures the safe removal of the waxed restorations. Another component of
the system is Biotec Wax Profile Sprues which are also organic with
high flexibility and excellent burnout characteristics. The sprues exhibit
minimal deformity while remaining completely compatible with Biotec Modeling
Wax, thus ensuring clean sprue channels for the best casting results for
pressible ceramics. The final compliment to this system is Wax-lite an
alcohol free wax wetting agent that exhibits excellent flow behavior, this
allows the investment to reach the finest recesses of the waxed pattern.
Thus smooth homogeneous surfaces and clean occlusal anatomy are achieved.
This system will be available soon so place your orders now to avoid delays.

Attachment Advice
Question: Often times there is not enough space for proper
aesthetics when placing a denture tooth over an attachment housing in a
cast partial. Can you recommend an attachment that is most suitable?
Answer: This is a common problem that most of us hope that we
don't have to address. However there are a few attachments we can rely
on like Bredent's VKS-OC. It's a ball stud type attachment with an
angulated arm that extends down and away from the crown. The miniaturization
of the standard 2.2 mm ball to 1.7 mm gives us the first advantage. The
second one is that the mini is available in a 30 or 60 degree angulation
which allows us to adapt it to different tissue configurations. Its lower
position and angle ensures ample vertical space while the miniature size
creates more buccal, lingual and mesial space. The attachment design should
solve our problem. Source; Peter T. Pontsa, RDT
Trade
News!
Visit us during Dentechnica
in Montréal on October 12th & 13th, 2001 at the Radisson de
Longueuil. We will introduce twenty new products from bredent as well as
present a seminar in French on the bredent attachments.
Dental Fear Alleviated
Acupuncture eases dental fears; people have a million excuses
for not going to the dentist but some actually suffer from an exaggerated
gagging reflex that makes dental treatment miserable. Now dentists in Great
Britain say acupuncture can help. Research published in the British Dental
Journal showed dentists who used acupuncture to stop the gag reflex were
able to perform standard dental treatments, such as filling and extractions,
on patients who other wise would have to be sedated. These patients often
avoided dental visits altogether because of the discomfort and embarrassment
associated with this condition. Estimates suggest that half of all Americans
will never seek dental care for fear of going to the dentist. Experts say
there are number of different reasons people develop fears over going to
the dentist. Source; Infodent #25/2001
Today's Product
Oxide-Stop saves time on soldering, reglazing, rebaking or adding porcelain.
Apply bredent's Oxide Stop onto all polished metal areas and during firing
or soldering. It prevents oxidation and discoloration of the metal. Afterward,
the protective layer is easily removed with hot water or steam, leaving
the metal polished and virtually untouched. The material essentially eliminates
the chance of margin damage from repolishing and is available in three
variations; semi-precious, silver-palladium and non-precious. For
more information call 800-250-5111.
