Same combined scaler + air polisher, two physical form factors. The PT-E sits on the operatory benchtop. The PT-B installs inside the dental unit cabinet. The decision is about your operatory's life stage — refurb, new build, or as-is.
Choose PT-E if your operatory is already built and you want to add combined scaling + air polishing without disturbing the layout. Plug-and-play.
Choose PT-B if you're doing a new build or full operatory refurb. Cleaner counter, integrated into the dental unit, but the install work is significant.
| Dimension | PT-E | PT-B |
|---|---|---|
| Form factor | Combined tabletop | Built-in (installed in dental unit cabinet) |
| Functions | Ultrasonic scaling + air polishing | Ultrasonic scaling + air polishing |
| Powders | Glycine, sodium bicarbonate | Glycine, sodium bicarbonate |
| Counter footprint | Visible on benchtop | Hidden inside cabinet |
| Mobility | Can move between operatories | Fixed to operatory |
| Installation | Plug and play | Plumbing + electrical + cabinetry integration |
| Time to deploy | Same-day | 1-2 days plus dental unit downtime |
| Best timing | Any time | New build or full refurb |
| Service access | Easy — remove and ship | Requires partial cabinet disassembly |
| Loaner during repair | Easier to arrange | Harder — built-in not interchangeable |
| Aesthetic / patient perception | Visible equipment on counter | Clean operatory, less equipment-heavy feel |
If yes — PT-B becomes a strong candidate because the integration work is happening regardless. If no — retrofitting a PT-B is expensive and disruptive; PT-E is the smarter call.
Multi-chair clinics sometimes share one combined unit across operatories. PT-E supports this; PT-B doesn't. If you'll standardise one device per chair (the more common modern approach), the question is moot.
For premium clinics where operatory cleanliness and visual minimalism are part of the patient experience, the PT-B's clean integration is a real advantage. For most clinics the PT-E's visible footprint is a non-issue — it sits on the hygiene cart with other instruments and equipment.
The device list price is broadly comparable. The total project cost differs:
When the operatory is being built or refurbished anyway, the marginal installation cost for the PT-B over the PT-E is small. When the operatory is finished and you're adding the device later, the gap can be substantial.
Both are serviced by Woodpecker distributors with the same parts catalogue and powder supply. The practical difference at service time:
For practices in regions with slow Woodpecker distributor response times, this matters. Ask specifically about service SLA for built-in versus tabletop units.
If you need erythritol-based subgingival biofilm management for stage III peri-implantitis maintenance — neither PT-E nor PT-B is the answer. You need an EMS Airflow Prophylaxis Master or GBT Machine. See EMS Airflow vs Woodpecker PT-E for the full premium-vs-cost-competitive trade-off.
If you already own an ultrasonic scaler and only need to add air polishing — neither is the right form factor. You want the standalone Woodpecker AP-H or a handpiece-style polisher like NSK Prophy-Mate neo.
