Crown Down for Nobel Biocare. The Compatible Implant Drill Kit.
You place NobelActive, NobelParallel Conical Connection, or NobelReplace. Your Nobel drills wear out on the same schedule as every steel kit, and Nobel replacement drills sit at the top of the market on per-drill pricing. Crown Down is a tungsten carbide implant drill kit that maps to Nobel's published osteotomy specifications, uses two drills per site instead of five to six, and doesn't require scheduled replacement.
Which Nobel Biocare lines does the kit cover?
Crown Down publishes a validated drilling chart for the NobelParallel Conical Connection line, and the same universal drill geometry prepares the osteotomy for the other Nobel implant families. For NobelActive and NobelReplace CC, the drilling-chart PDF is issued on demand once we confirm the implant diameters and depths your practice actually places.
NobelParallel Conical Connection
The parallel-walled Nobel line with a conical abutment interface. Drilling chart covers Ø 3.75, Ø 4.3, and Ø 5.0 mm implant diameters at Nobel’s standard lengths.
NobelActive
The tapered, self-tapping Nobel line. Drilling chart maps the 2-drill protocol to Nobel’s specified undersized osteotomy for aggressive-thread engagement. Available on request — book a clinical demo below.
NobelReplace Conical Connection
The tapered Nobel line with the conical connection platform. Drilling chart maps the 2-drill protocol to the diameters Nobel specifies for the tapered osteotomy. Available on request.
The universal handpiece interface and the tungsten carbide drill material don’t change across Nobel lines — only the mapping to each line’s specific osteotomy diameters does. That mapping is a chart, not a hardware change. If your practice places a mix of NobelParallel CC and NobelActive (common), one Crown Down kit covers both.
What actually changes on a Nobel case with Crown Down.
The osteotomy is prepared to the same final diameter and depth Nobel specifies. Primary stability targets stay the same, implant selection stays the same, restorative components stay the same. What changes is the drill sequence itself: one cortical pass with a tungsten carbide drill matched to the implant diameter, then one trabecular pass with the paired second drill. Two drills per site instead of the pilot → intermediate → final sequence in a Nobel surgical cassette.
Nobel steel cassette sequence
- 1. Round bur (crestal marking)
- 2. Pilot drill Ø 2.0 mm
- 3. Twist drill Ø 2.4 / 2.8 mm
- 4. Twist drill Ø 3.2 mm
- 5. Twist drill Ø 3.8 mm (NP 4.3)
- 6. Final drill matched to implant diameter
5 to 6 drills, 800 to 2,000 RPM, continuous saline irrigation. Replaced roughly every 20 to 50 osteotomies as the cutting edge dulls. Wide-platform NobelActive cases add a bone tap step for very dense bone.
Crown Down protocol on the same case
- 1. Cortical drill matched to implant diameter
- 2. Trabecular drill (paired partner)
2 drills, ~250 RPM, no saline dependency. Solid tungsten carbide, engineered for unlimited clinical use. Osteotomy is prepared to the exact final diameter Nobel specifies for the chosen implant, including NobelActive’s undersized preparation.
Surgeons switching a Nobel workflow to Crown Down report that the biggest visible change is the surgical assistant’s tray. A standard Nobel surgical cassette lays out 6 to 10 sequenced drills with color-coded rings, plus a bone tap for dense-bone NobelActive cases. The Crown Down tray shows one cortical drill and one trabecular drill for the diameter being placed, plus one set of coded depth stoppers. Assistants report the setup reads at a glance and the drill-handover count drops noticeably per case.
5-year cost: Nobel Biocare steel kit vs Crown Down.
Nobel Biocare surgical cassettes are well-engineered. They also depreciate on schedule: the stainless steel drills dull under normal clinical drilling loads and the practice reorders replacement drills to keep the tray in cutting condition. Nobel’s per-drill replacement pricing sits at the higher end of the market, which is what turns the sticker price into a substantial operating cost over a 5-year window.
| Cost line | Nobel steel kit | Crown Down |
|---|---|---|
| Initial kit purchase | $2,500 to $4,500 | $3,495 |
| Drill replacement / year | $700 to $2,000 | $0 |
| 5-year total | $6,000 to $14,500 | $3,495 |
Ranges depend on annual case volume and replacement cadence. The dedicated drill cost calculator runs the exact numbers for your case volume and current Nobel Biocare invoice pricing.
The handpiece question
Same handpiece, same tray, same case flow.
Crown Down drills use a Morse taper 1.5° lock with a 4.0 mm well and an 18 mm shank length. This is the same open-standard interface that Nobel Biocare’s freehand surgical drills use (and Straumann, Zimmer Biomet, and every other major implant system). Any standard contra-angle handpiece on your Nobel tray already accepts Crown Down drills without an adapter.
No proprietary driver, no push-button retainer requirement (which some older NobelReplace guided-surgery drills use in specific tray configurations), no reprocessing change. The kit ships, you sterilize it, and it replaces the Nobel drill sequence on the tray you already have.
