. . A17 Dental Tribune Canada Edition | March 2016 INDUSTRY Elbow your way to better health D entists, hygienists and dental assistants face on a daily basis all of the top conditions needed to develop musculoskeletal disor- ders. Dental work requires precision and control in move- ment — so static positions can result in fatigue in the muscles of the neck, the back and the shoulders. After a few years or even months, the muscle fatigue may cause ailments, pain or even more severe conditions, such as tendinitis, bursitis, neck pain, disk herniation and others. If I work with my arms close to my body, can I avoid muscle tension? Even when your arms seem relaxed along your body, the shoulder and upper back muscles have to be con- tracted to keep the stability required for the precise work of your hands. These muscle contractions can reduce the blood flow up to 90 percent, which causes fatigue to accumulate and weaken your muscles and articulations. Why use mobile elbow supports? The Posiflex mobile elbow support system was de- veloped to diminish the charge to the upper body in order to favor a good bloodstream. A scientific study demonstrated that using the Posiflex system con- tributes to achieving a more secure and comfortable work posture while signifi- cantly reducing muscle contractions in the shoulders, neck and upper body. This unique concept follows body movements. The elbow rests offer an appropriate sup- port of the arms while preserving the freedom of movement. Precision work requires concentration and effort. We forget ourselves when we are concentrated on a task. The elbow sup- ports enable practitioners to keep a good posture as they keep you in line. Do I have to always be on the supports to get the benefit? It is not possible to be on the supports 100 percent of the time. The studies demonstrated that with 50 per- cent of the time on the support, bloodstream is suf- ficient to prevent and diminish tension. After a short learning curve, the majority of users are on the sup- ports 80 to 90 percent of the time. Why invest in a dental stool? Dental professionals can easily spend eight to 12 hours a day on a stool. In fact, it is the piece of equipment you use the most and, generally, it is also the most neglect- ed. You pay attention to your patient comfort, so what about your comfort and that of your employees? The investment is modest and quickly profitable compared to costs created by medical treatments or leave from work. Do you have to plan long proced- ures early in the week because your body can’t do it on Thursdays? How should the patient chair be adjusted to keep the practitioner in good posture? Eyes-to-task distance is the key for good posture. When the patient chair is placed low it forces you to bend your neck, even with loupes, creating tensions. Furthermore, because of lack of leg room, the operator must straddle the chair or, worse, sit on the tip of the seat. This pos- Michelle Fontaine, RDH, demonstrates the ergonomic improve- ment in her work position enabled in part by her use of Posiflex free motion elbow supports. Photos/Posiflex Design Repetition.

Factors contributing to development of musculoskeletal disorders: By VOCO Staff VOCO recently introduced Futurabond M+, a uni- versal single-bottle adhesive. Futurabond M+ versatil- ity enables it to be used in self-, selective- or total-etch mode without any additional primers on virtually all substrates. Futurabond M+ achieves total-etch bond strength levels with all light-, self- and dual-cure resin- based composites, cements and core buildup materials. With a dual-cured activator, Futurabond M+ will self- cure without any light activation, which, according to the company, offers a big advantage for endodontic ap- plications such as post cementation where it avoids the pooling effect, a problem with light-cured adhesives. Futurabond M+ also adheres well to metal, zirconia and ceramic, making extra primers unnecessary. Futurabond M+ needs only one coat and takes 35 seconds from start to finish. Its low film thickness of 9 microns makes bonding margins invisible (no “halo” effect) and prevents pooling problems. It does not need to be refrigerated. Benefits include its indication as a desensitizer for use under amalgam restorations or on hypersensitive tooth necks as a protective varnish for Single-bottle adhesive self- cures with no light activation glass ionomers and an intraoral repair of ceramic res- torations. For more information on Futurabond M+ you can visit the VOCO website at www.voco.com.

Photos/Provided by VOCO VOCO’s Bifix Temp offers 90 seconds of working time and sets in four minutes. VOCO’s Bifix Temp offers high esthetics with a simple ap- plication that provides users with visually pleasing results. The translucent and tooth-like universal shade blends with highly esthetic temporaries, does not shine through and promotes natural ap- pearance of temporary restorations. Thanks to Bifix Temp’s low film thickness, temporaries can be cemented to fit without adjustment. As a composite-based dual-cure material, Bifix Temp offers 90 seconds of working time and sets in four minutes. The light-cure mode offers the user control and easy removal of excess material via a “tack-cure” technique that activates an initial elastic gel phase. Any unwanted residues are easy to locate and remove as Bifix Temp’s universal shade stands out well against the gingiva. Bifix Temp comes in an auto-mix syringe with very short tips, making application precise and economical. To learn more, you can visit www.voco.com. Temporary luting material delivers natural translucent appearance PDC BOOTH No. 1335 ition does not provide lumbar support or a safe position. Many speakers and authors favor a higher position of the patient chair with the patient lying flat. The arms stay close to the body and the forearms are flexed.
