What is the Woodpecker PT-B?
The Woodpecker PT-B is Woodpecker's built-in counterpart to the PT-E tabletop unit. Same combined functionality — piezoelectric ultrasonic scaling plus chair-side air polishing — but with a different physical form factor. Instead of a tabletop device you place on the cart, the PT-B installs inside the dental unit or operatory cabinet, with handpieces emerging through the standard chair-mounted tubing.
The PT-B is a specification-time decision: you're choosing it when you build a new operatory or refurb an existing one. Retrofitting a PT-B into an operatory that wasn't designed for it is more involved (water, air, electrical integration) and significantly more expensive than buying a tabletop PT-E.
Who typically buys the PT-B?
- Clinics doing a new build who want to integrate combined scaling + polishing from day one.
- Practices doing a full refurb of one or more operatories — the right moment to remove the tabletop unit from the visible footprint.
- Multi-chair clinics standardising the same chair-side workflow across operatories, where the built-in form is preferred for hygiene and ergonomics.
- Buyers who already considered the PT-E and decided the visual footprint and counter-top space are worth optimising.
PT-B vs PT-E — which one fits your operatory?
The two devices share their core engineering: ultrasonic piezo scaling, glycine + sodium bicarbonate air polishing, the same handpiece family. The decision is about where the box lives:
- Choose PT-E if you're equipping an existing operatory without rebuilding it, you want to move the unit between chairs, or you're early-stage in your hygiene workflow rollout and want flexibility.
- Choose PT-B if you're building or refurbing the operatory anyway, hygiene is a steady-state revenue line, and the counter-top space + cable management justify the integration cost.
If you already own the PT-E, switching to the PT-B usually doesn't make sense as a standalone investment — it's a decision to make at the operatory-build moment. See the PT-E overview for the tabletop equivalent.
Powders and consumables
The PT-B runs the same powder family as the PT-E — glycine and sodium bicarbonate on the air polishing module. The Woodpecker-branded "Super Powder" sold in Europe is a glycine formulation, not erythritol. Erythritol is patented by EMS in the EU and not validated on Woodpecker hardware. If your hygiene protocol calls specifically for erythritol, the PT-B is not the right device — look at the EMS Airflow Prophylaxis Master or the newer GBT Machine instead.
Ultrasonic tips for the scaling module follow Woodpecker's piezo tip range. Confirm tip compatibility with your existing protocols before ordering.
What to ask the distributor
- Installation scope — exactly what plumbing, electrical and cabinetry work is included in the quote, and who does it.
- Compatibility with your dental unit brand — not all chairs accept all built-in modules cleanly.
- Loaner during installation / repair — for built-in units the downtime risk is higher than for tabletops.
- Service response time in your region.
- Stock of validated powders locally.
- Warranty length on the unit and on the installation work separately.
- Training on the combined workflow for the hygiene team.
Alternatives to compare
- Woodpecker PT-E — Tabletop version of the same combined system. Same workflow, no installation.
- EMS GBT Machine — Premium cart-style integrated unit; reference equipment in GBT workflows. Different price tier.
- Mectron built-in modules — Established European combined built-in alternative.
- NSK Varios Combi Pro2 — Tabletop combined system in the same category, comparable to PT-E rather than PT-B.
Frequently asked questions
Can I retrofit the PT-B into an existing operatory?
Technically yes, but it's significantly more expensive and disruptive than buying a tabletop PT-E. Most clinics that decide on the PT-B do so at the new-build or full-refurb stage.
Is the PT-B subgingival-capable?
Subgingival capability depends on whether the SKU includes a validated subgingival nozzle and the right powder. Confirm in writing with the distributor before purchase — don't assume it's included.
Can I use erythritol powder in the PT-B?
Not in Europe. EMS holds the European patent on erythritol air polishing powder. Outside Europe, confirm with the local distributor what powders the SKU is validated for.
How long does PT-B installation take?
Depends on whether you're doing a new build (typically same-day, as part of the chair installation) or a retrofit (1–2 days plus reassembly). Ask the distributor for an installation timeline up front and what operatory downtime to plan for.
