Safe protection and easy operation
Whether it’s the removal of dental plaque, application of a rubber dam, removal of fillings or the transection of crowns and bridges, each of these treatments requires the aspiration of a multitude of particles from patients’ mouths. High-speed and oscillating instruments must be cooled with water to protect the sensitive pulp-dentin area, thereby releasing aerosols. The mixture of droplets from the cooling water, saliva, blood and microorganisms presents a high risk of infection. Moreover, the highly accelerated air-flow particles can lead to irritation of the oral mucosa. Now, the new prophylaxis cannula from Dürr Dental provides highly effective protection. Its ergonomic design and integrated protective shield are unique. This new product demonstrates its strengths particulalry in air-flow treatments. But its flexibility means that the cannula can be applied to many other situations.
The secret of the new prophylaxis cannula’s success lies in its design. The non-slip surface of the handpiece and the rotating and removable protective shield are instantly noticeable. The shield can be effortlessly adapted to any treatment situation and reduces the risk of irritation of the oral mucosa to a minimum. In comparison to previous cannulae, the opening through the protective shield is significantly larger, and has been demonstrated to aspirate twice as much aerosol. The cannula’s flexibility also allows treatment to be undertaken without assistance,. because the shield precisely channels the intake flow through the cannula. It reliably takes up the aerosol with air-flow powder in both buccal, and palatal, applications. Special bleed-air intakes prevent the reflux of secretions from the suction system. At the same time, large-scale dissemination of microparticles in the treatment room is considerably reduced. Thus the device also significantly contributes to cross-infection control for patient, dentist and staff.
The applications for the new cannula are by no means restricted to prophylaxis. Its versatility also benefits restorative and prosthetic treatments. In rubber dam applications, for example, its easy positioning makes aspiration perceptibly more comfortable. It has been shown, for instance, to aspirate the rinsed etching gel and its aerosol so thoroughly that it makes no contact with the healthy hard tooth tissue. Even when more water is required, such as for tooth reduction, the cooling liquid is optimally suctioned off.
