Voices from practice5 dentists and dental technicians
I can no longer imagine my daily practice without the SILENT XS. When you want to grind an aligner, a denture, or a plaster model right at the treatment chair, you not only end up looking terrible yourself afterwards — the treatment room is also full of dust. With the SILENT XS, it all stays hygienic and clean.
"Anyone who wants to adjust aligners hygienically, cleanly, and without stress, remove pressure points, or correct orthodontic appliances — they need the SILENT XS. Annoying denture dust is a thing of the past."
"In my practice there are always small grinding jobs that don't require a dedicated lab workstation. Lightweight, mobile, ready to use instantly — the battery lasts a long time, and cleaning is straightforward."
"I also work with 3D-printed resins — very fine dust, lots of particles. Easy assembly, easy cleaning, good visibility thanks to the LED. Easy to carry between rooms."
"In many practices, dental technicians often lack a suitable workstation — limited space, no dedicated suction. This is exactly where the SILENT XS is the solution for me: mobile, battery-powered, and instantly ready. Whether on the go in the practice or separating zirconia in the lab — I work cleanly, independently, and with my own setup."
