A BULLETIN DEALING WITH ISSUES FOR DENTAL HEALTH PROFESSIONALS
Inside This Issue
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. Source; Peter T. Pontsa RDT.

The Biotec Organic Wax System is comprised of:
Bredent’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.

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.

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.
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
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.
