Two implant sites at lower right #45 and #47, prepared live with two tungsten carbide drills. No ascending sequence, no drill swaps between diameters.

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.

What Makes Crown Down Different
Explore Crown Down from the perspective that matters most to your practice.
Practice Economics
Solid tungsten carbide and a lifetime sharpness warranty replace the recurring drill-replacement line item with a one-time kit purchase.
See the 5-year ROILong-Term Cutting Performance
Carbide is ~13x harder than surgical stainless steel and does not dull under normal clinical conditions; the same drill cuts as effectively in year five as it did on day one.

Universal compatibility across all major implant systems - your kit isn't tied to a single implant supplier or their forced accessory cycle.

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 blind spot to worry about.
Solid tungsten carbide
Eight drills, ~13× 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.
7 clinician reviews and counting
“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
“Same torque, different bone, different biology.”
“This is one of the principles behind the Crown-Down technique: by selectively reducing cortical interference, insertion torque may better reflect the true mechanical contribution of the medullary bone while reducing excessive crestal compression. Same torque, different bone, different biology.”

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.
Thermal profile
Solid tungsten carbide’s higher thermal conductivity (around 110 W/m·K vs. steel’s 18 W/m·K) draws heat away from the osteotomy during preparation. Learn about implant drilling heat.
Long-term ownership
Carbide drills maintain cutting performance across repeated cases, so periodic drill replacement isn’t a recurring line item on the practice’s supply budget.
Simpler workflow
The 2-drill protocol handles cortical and trabecular preparation with a single instrument change per site: fewer swaps, cleaner tray flow, faster turnover.

Your 5-year savings
Modeled on the industry midpoint of ~5 drill-passes per implant and a ~25-osteotomy service life for a stainless-steel edge, at $100 per replacement drill.
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 system includes 15 mm and 20 mm surgical kits, individual tungsten carbide drills from Ø 2.75 mm to Ø 6.0 mm, and 3D stoppers for guided preparation.
