Do I need to put the equipment to use on a real patient?

No — a phantom acceptance test or staff-training scan that exercises the equipment's revenue function is sufficient under common CPA practice. The strictest reading requires real patient use, but that's rare. Your CPA's interpretation governs.

What if I'm a de-novo and not yet open?

Section 179 requires the equipment to be placed in service in your trade or business. A de-novo without operations doesn't have a trade or business yet. If you can complete a phantom acceptance test before 12/31 and the practice has cleared other operational hurdles (licensure, malpractice in force, signage), some CPAs treat that as sufficient. Get this in writing from your CPA.

Section 179 Dental Equipment Financing

Updated May 31, 2026

Section 179 lets you deduct the full cost of qualifying dental equipment in the year it's placed in service — financed or not. The catch is timing: "placed in service" means installed and capable of generating revenue, not just delivered. For a CBCT that means calibration; for CEREC, the milling chamber operational. Plan back from 12/31 with real install windows.

Structure

How this product is shaped.

Financed equipment qualifies. Section 179 does not require cash purchase. EFA / $1-buyout / capital lease all let the lessee claim the deduction. FMV lease does not (lessor depreciates).
Deduction limit — confirm with CPA. The deduction cap and phase-out threshold are indexed annually. Always confirm current-year figures with a CPA before relying on a projection.
Place in service by 12/31. Operational and revenue-capable, not merely delivered. Build the install timeline into your funding plan.

Install timelines that matter

CBCT: 4–6 weeks from order. Includes room shielding evaluation, install, calibration, and acceptance testing. Add another 1–2 weeks if your state requires shielding plan approval.

CEREC / chairside CAD/CAM: 2–3 weeks. Includes hardware install, software setup, calibration, and your first scan-to-mill restoration.

Intraoral scanner (iTero, Primescan, Medit): 1–2 weeks. Largely plug-and-play but requires staff training to scan eligibility for "placed in service."

Dental chairs: 1–2 weeks. Requires plumbing/electrical, calibration, and a first patient seated.

What disqualifies a Section 179 claim

Equipment ordered before 12/31 but delivered after 12/31 — disqualified for the current year. Equipment delivered before 12/31 but not yet installed/calibrated — disqualified. Equipment installed but where the practice has not yet used it for any revenue-generating procedure (even a phantom acceptance test counts) — gray area; CPAs vary.

Bonus depreciation rules and phase-down schedules are also indexed annually and interact with Section 179. Always confirm with a CPA before relying on any tax projection.
