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.

Sizes & diameters
Crown Down drills come in eight diameters from Ø 2.75 mm to Ø 6.0 mm, each identified by a drill number. The table maps every drill to its diameter, its role in the 2-drill osteotomy, and the implant diameters it typically prepares. Exact drill pairing per implant is defined on the system-specific drilling charts.
| Drill | Diameter | Osteotomy role | Typical implant Ø |
|---|---|---|---|
| #20 | Ø 2.75 mm | Trabecular / pilot | 3.0–3.3 mm |
| #30 | Ø 3.0 mm | Trabecular | 3.3–3.5 mm |
| #35 | Ø 3.5 mm | Cortical or trabecular | 3.5–4.0 mm |
| #40 | Ø 4.0 mm | Cortical or trabecular | 4.0–4.3 mm |
| #45 | Ø 4.5 mm | Cortical or trabecular | 4.3–4.8 mm |
| #50 | Ø 5.0 mm | Cortical or trabecular | 4.8–5.0 mm |
| #55 | Ø 5.5 mm | Cortical | 5.0–5.5 mm |
| #60 | Ø 6.0 mm | Cortical | 5.5–6.0 mm |
Typical implant-diameter ranges are a general guide. For how the two drills work together, see the 2-drill protocol and the cortical drill reference.

Shop drills
Most practices switch over to the complete 8-drill tungsten carbide kit. Individual drills are available for the rare case of a lost or misplaced drill, not for routine replacement.
Complete kit
8 solid tungsten carbide drills (Ø 2.75 to 6.0 mm), 2 reusable depth stoppers, universal sizing chart, and autoclave tray. Available in 15 mm and 20 mm working lengths.
Individual drills
Every diameter (#20 through #60) available individually in 15 mm and 20 mm lengths. Intended for replacing a misplaced drill or adding a specific diameter — not for routine replacement, because the drills don’t wear out.
Drill material
The dental implant drill material determines how much heat is generated, how quickly the cutting edge degrades, and how many procedures you can perform before replacement.
Stainless steel
The vast majority of dental implant drills are surgical stainless steel. Inexpensive to machine, familiar to every clinician, but with fundamental material limits.
Solid tungsten carbide
Tungsten carbide is one of the hardest materials used in surgical applications; the VP10X grade used in Crown Down drills is approximately 8× harder than stainless steel. Its thermal conductivity is 6× higher.
For the full side-by-side breakdown, see carbide vs. stainless steel implant drills.
A dental implant drill is a surgical instrument used to prepare an osteotomy in alveolar bone so a dental implant fixture can be placed.
Every implant placement begins and ends with the dental implant drill. Drill quality directly determines how cleanly the osteotomy is cut, how much heat is generated against bone, and how predictable primary stability will be at the moment of placement.
The single biggest variable in clinical performance is the drill material. Stainless steel dulls quickly and traps heat in bone. Solid tungsten carbide stays sharp through unlimited clinical use and pulls heat away from the osteotomy. Every claim on this page rests on that one material distinction.
The deeper technical treatment of that argument, with 13 peer-reviewed citations and in-vitro dental-stone imagery of steel-drill edge collapse, is on the Wear-Proof Implant Drills clinical analysis, which also explains why the Crown Down drilling sequence is required to make solid tungsten carbide safe in clinical use.

Drill anatomy
Every implant drill, regardless of brand or material, shares the same functional anatomy. Each feature has a direct effect on cutting efficiency, heat generation, and how cleanly the osteotomy wall is prepared.
Cutting edge
The sharpened tip geometry that actually shears bone. Its angle and sharpness determine whether bone is cut cleanly or burnished and torn. This is the first feature to degrade as a steel drill dulls, and the reason edge-holding hardness matters most.
Flutes
The helical grooves running up the drill body. They channel bone chips up and out of the osteotomy so debris doesn’t pack against the cutting edge and generate friction heat. Flute geometry also lets a large-diameter drill collect autogenous bone chips for grafting.
Depth markings
Laser-etched or grooved reference lines that let the clinician read working depth directly against the crestal bone during drilling, typically at 6, 8, 10, 12, 13, and 16 mm.
Shank
The upper end that seats into the surgical handpiece or contra-angle via a standard latch-type connection — the same interface Nobel, Straumann, and other brand- specific drills already use.
Depth stopper
A collar that locks onto the drill shank to mechanically cap the drilling depth. Crown Down’s coded 3D stoppers register against a surgical guide sleeve for guided cases in 8, 10, and 12 mm working depths.
Body & diameter
The overall drill diameter defines how wide the osteotomy is cut. Implant drills are sold in a graded set of diameters so the site can be widened to match the exact fixture being placed - detailed in the size chart below.
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.

Drill anatomy
A standard drilling kit contains four functional drill types. Manufacturers may name them differently, but the role of each is consistent across systems. For a deeper reference on every drill category plus sizes, RPM, and drilling sequences, see the complete implant drill guide.
1. Pilot drill
The narrowest drill in the kit (typically 2.0 to 2.2 mm). Marks the entry point and establishes initial trajectory and depth through the cortical plate.
2. Twist drills
Sequential drills of increasing diameter that progressively widen the osteotomy. Conventional steel protocols use 3 to 6 twist drills per site.
3. Final shaping drill
Matches the implant’s exact taper and apical geometry. Determines the final dimensions of the osteotomy and prepares it for the implant fixture.
4. Depth-control drill
Used with a depth stopper or 3D-printed surgical guide to lock in the apical limit of the osteotomy, especially for guided implant surgery.
The Crown Down system consolidates these four roles into a 2-drill protocol using solid tungsten carbide. One drill, the cortical drill, performs the crestal pass; a second prepares the trabecular bone undersized for intentional osseocompression. The same two drills ship on Crown Down’s surgical implant kit for freehand and mixed workflows, or on the guided implant drill kit with coded 3D depth stoppers for template-based cases. For the full transactional breakdown, see the implant drill kit page.
Crown Down is built for dentists who want a smarter way to prepare implant osteotomies, not a slightly-different version of the same drill kit.

The 2-drill tungsten carbide protocol is backed by internal material testing, thermal measurement, and ongoing clinical use across implant systems.
1,000 osteotomy cycles each in bovine rib, pig rib, and bovine tibia at 22°C. No visible wear damage observed across all three internal tests.
Independent studies on implant drill material, heat, and repeated-use degradation: Koo 2015, Mendes 2014, Harris & Kohles 2001, Yalcin 2025.
Documented 5-year follow-up of a Neodent GM implant placed with the Crown Down protocol in a complex medically-compromised patient.
Disclosure: Internal testing was performed on benchtop bone substrates under controlled drilling conditions and is intended for comparative reference. Clinical outcomes depend on operator technique, drilling parameters, and case-specific anatomy. Clinicians should follow their training and clinical judgment when selecting drilling protocols.

“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.”

Buying checklist
Four criteria separate a drill kit that earns its place in your practice from one that becomes a recurring replacement line item.
Durability
The drill should maintain its cutting edge over hundreds or thousands of procedures, not degrade after 20.
Heat management
The drill should conduct heat away from the cutting edge efficiently, so bone temperature is not driven by the drill material itself.
Workflow efficiency
Fewer drills per site means faster procedures, less instrument management, and more patients per day.
Compatibility
Your drills should work with any implant system, not lock you into a single brand’s ecosystem.
