The 2-drill osteotomy protocol: one instrument change per site, a simpler tray and less to set up. Built around solid tungsten carbide, for guided and freehand implant surgery. Guaranteed against wear-related loss of cutting performance.

Live Clinical Case
Two implant sites at lower right #45 and #47, prepared live with two tungsten carbide drills. No ascending sequence, no drill swaps between diameters.
Case by Dr. Ernesto Antonio Pichardo Tejada, DDS · 18+ months of daily Crown Down use
Matched-diameter drill clears the dense crestal cortex in seconds.
Trabecular drill completes the site, no ascending sequence.
The hardest bone type most clinicians will ever prepare.
Two adjacent osteotomies prepared with the same 2-drill sequence.
The 2-drill workflow
The 2-drill protocol is built to keep the chair-side workflow simple, from the first cut to the implant.
Cortical first, then trabecular. No long ascending sequence to work through.
A single swap per site means a simpler tray and a more streamlined osteotomy.
Standard latch contra-angle interface. No proprietary driver to buy or learn.
No scheduled replacement count, so no resharpening or reorder cycle. Inspection and reprocessing still apply.

What Makes Crown Down Different
Explore Crown Down from the perspective that matters most to your practice.
Fewer Steps
The 2-drill protocol handles cortical and trabecular preparation with a single instrument change - fewer swaps, a simpler tray, and a more streamlined osteotomy. Less to set up, less to swap, less to track.
See the protocolChair-Side Convenience
Standard latch contra-angle interface with no adapter or proprietary driver, and nothing to resharpen or reorder on a schedule. For guided cases, confirm sleeve, stopper, working length and planned depth first.
Check compatibilityThermal Control
Material, drill condition, speed, pressure and cooling all affect heat. Follow the applicable technique; material properties alone do not establish thermal safety.

Advanced tungsten-carbide instrumentation signals a modern, evidence-based practice, and gives you predictable control every osteotomy.

The Kit
Eight solid tungsten carbide drills. A 2-drill protocol that runs guided or freehand. No replacement cycle to plan around, no drill-life math to reconstruct after the fact.
No replacement cycle
Cutting performance guaranteed for the life of the kit. No drill-wear schedule to track.
Solid tungsten carbide
Eight drills, roughly 8× harder than surgical steel.
Universal compatibility
Fits every major implant system: Nobel Biocare, Straumann, Zimmer Biomet, Neodent, BioHorizons, Dentsply Sirona, MegaGen, Osstem, and more.
15 or 20 mm lengths
Same 2-drill protocol, matched to your osteotomy depth.
Guided or freehand
3D depth stoppers lock into sleeved guides for planned cases. The same 2-drill sequence runs freehand when you don't have a guide. One kit, either workflow.

“Two years in and I haven't replaced a single drill.”
“I switched to Crown Down two years ago and haven't replaced a single drill. My implant site prep is noticeably faster and I have much better tactile feedback through the bone.”
Luxembourg
“My assistants noticed the difference on day one.”
“The 2-drill protocol cut my osteotomy time significantly. My assistants noticed the difference on day one: fewer instruments to manage, faster turnover between patients.”
Israel
“18 months of daily use and the drills still cut like new.”
“I was skeptical at first, but after 18 months of daily use the drills still cut like new. The heat reduction is real, and my patients report less post-op discomfort.”
Dominican Republic
“That line item is simply gone now.”
“What sold me was the economics. I used to budget for replacing dull drills every quarter, and that line item is simply gone now. The carbide holds its edge case after case, and the consistency that gives me during osteotomy prep is worth as much as the savings.”
Montreal, Canada
“My team adapted to the protocol within a week.”
“Going from a full sequential tray down to two drills changed how my surgical days run. There is less to set up, less to track, and my guided cases flow faster without sacrificing accuracy. My team adapted to the protocol within a week.”
Pierrefonds, Canada
“The thermal difference is something I can feel through the handpiece.”
“The thermal difference is something I can feel through the handpiece, and I see it in how cleanly the sites heal. Preserving bone vitality matters to me, and being able to collect autogenous chips on the same pass has made grafting in my practice far more straightforward.”
Dr. Gadi Kalihman
Kiryat Gat, Israel
“Placing implants has become much faster for me.”
“Since I started using the Crown Down kit, placing implants has become much faster for me. Two drills instead of a long sequence means fewer instrument changes, and I move through each osteotomy with less interruption.”

Testing & Research
Three different classes of evidence, kept separate: in-house bench testing of Crown Down drills, independent peer-reviewed research on drill wear and heat, and documented clinical cases.
Bovine rib, pig rib, and bovine tibia at 22°C. No visible wear observed across internal testing.
In-house bench testKoo 2015, Mendes 2014, Harris & Kohles 2001, Yalcin 2025 on drill material, osteotomy heat, and repeated clinical use.
Independent researchOne documented Neodent GM case placed with the Crown Down protocol in a medically-compromised patient. Single-case observation, not systematic cohort follow-up.
Published case historyAnother Approach
You already have a drilling system that works. The question isn’t whether Crown Down replaces it. It’s whether it gives you another useful option worth considering alongside it.

Your 5-year savings
Modeled on the industry midpoint of ~5 drill-passes per implant and a ~20-osteotomy service life for a stainless-steel edge, at $80 per replacement drill.
Net over 5 years, counting the $3,495 Crown Down kit and the $1,200 steel kit you’d otherwise buy: $2,705 saved
The Crown Down kit is a one-time $3,495 purchase and is guaranteed against wear-related loss of cutting performance for the life of the kit -- no scheduled replacement drills.

About Crown Down
Crown Down was designed by an implant surgeon to solve his own tray - fewer drills, no saline dependency, and cutting geometry that holds its edge across every osteotomy he places.
Meet the Founder
Founder & CEO · 30+ years, 6+ patents
Dental surgeon and inventor with three decades in implant dentistry. Crown Down is a system he built chair-side to solve a problem he kept running into himself - too many drills per site, too much saline, and steel edges that dulled long before the practice was ready to replace them.

Book a 15-Min CallCrown Down is a dental implant drilling kit made from solid tungsten carbide. It uses a 2-drill osteotomy protocol to prepare implant sites for guided and freehand surgery, replacing the long progressive drill sequences of conventional steel kits. The Crown Down lineup includes 15 mm and 20 mm surgical kits and individual tungsten carbide drills from Ø 2.75 mm to Ø 6.0 mm. Coded 3D depth stoppers for guided preparation (8, 10, and 12 mm) are available separately as a guided-surgery accessory.
