Friday afternoon, a patient with a broken temporary restoration is sitting in the chair. The quick adjustment is not a problem - if it weren't for the dust that stubbornly settles on clothing, furnishings and even on the patient. This scenario is common in many dental offices and not only looks unprofessional but also impairs efficiency. However, with the right technology and the right tools, this problem can be solved smartly.

1. Position is key: Mobile suction unit and correct working ergonomics

Let's start with the basics: the working position. When performing little milling chairside choirs, dentists often tend to adopt an ergonomically unfavorable posture. This not only leads to physical strain but also hinders dust collection.

Quick tip:

Adjust your position to ensure that the workpiece is in front of you in a 7 o'clock to 12 o'clock position. Position the SILENT XS mobile suction unit SILENT XS in front of you, at a slight inclination to the workpiece.  In this way, dust is reliably collected without the device impairing your view.

2. Light in the dark: Optimum visibility for dust Collection

Precision work requires excellent visibility. When it comes to extraoral adjustments, the surgical lighting is not always optimally positioned.

Quick tip:

Use a suction unit with integrated LED lighting. SILENT XS features a light source which is directly focused on the working area, minimizing shadows and revealing the finest details. As a result, work quality is significantly improved

3. Battery powered dust collector: Cordless for maximum flexibility

Cables are tripping hazards and reduce freedom of movement - especially in an already cramped treatment environment.

Quick tip:

Rely on battery operation! Renfert's cordless SILENT XS suction unit can be positioned flexibly and easily moved to different treatment rooms. Thanks to a sufficiently long operating time, SILENT XS can be used several times throughout the day. Simply charge the battery* overnight and the device is fully operational the following morning.
* Not included in the scope of delivery. Commercially available NiMH 8 x 1.2V / AA / >1200mAh can be used.

4. Filter power: Dental suction unit and the best technology for clean air

Not all dental suction units are the same. It all depends on the filtration technology.

Quick tip:

Look for H13/HEPA filters with a high separation efficiency. They filter even the finest particles.  Not only does a high-quality filter ensure clean air, but it also ensures a long service life - a filter change every 2-3 weeks is generally sufficient when using SILENT XS on a regular basis.

5. Integrating instead of improvising: High-performance dental suction in the clinical workflow

Even the best suction system is useless if it is not implemented systematically. The key to success lies in seamless integration into the daily clinical routine.

Quick tip:

Define and communicate scenarios for the use of the SILENT XS within the team. A few examples: Fitting temporary restorations, adjusting CAD/CAM restorations or grinding in occlusions.  establish a dedicated place for the charging station, ideally at a central location in the dental office, and check the charge status (charge status indicator) regularly as part of your routine.

Conclusion: Small things make all the difference

Dust-free chairside work is not a luxury, but part of a professional working method. Thanks to the SILENT XS mobile dust extractor and the right steps, a potentially annoying issue becomes a smooth workflow.

The SILENT XS is more than just a technical solution - it is a statement of quality awareness and efficiency in the dental office. True to the motto: Making work easy.
