Why choose the 20 mm Crown Down kit instead of the 15 mm kit?

Both kits use the same 2-drill protocol and the same solid tungsten carbide implant drills. The 20 mm kit is the right choice if you regularly treat longer osteotomies or deeper guided cases that require more than 15 mm of working drill length.

Are the 20 mm drills compatible with surgical guides?

Yes. The 20 mm length is intended for cases where a surgical guide adds height above the osteotomy and a longer drill is required to reach planned depth.

How long do Crown Down tungsten carbide drills last?

Crown Down drills are engineered for long-term clinical use under normal drilling conditions and are guaranteed against wear-related loss of cutting performance. They are designed to resist routine dulling that drives steel drill replacement.

Can I run the same protocol on both the 15 mm and 20 mm kit?

Yes. The Crown Down 2-drill osteotomy protocol is identical between the 15 mm and 20 mm kits. Only the drill working length differs.

What is the price of the 20 mm Crown Down kit?

The 20 mm Crown Down implant drilling kit is $3,495.00 USD. Practice and volume pricing are available on request.

CD-KIT-L020Solid Tungsten CarbideFDA clearedUniversal: works with all major implant systems and platforms

The Crown Down 20 mm implant drilling kit replaces a long steel drill sequence with two solid tungsten carbide drills per implant site, in 20 mm working lengths for longer osteotomies. Eight drill diameters from Ø 2.75 mm (#20) to Ø 6.0 mm (#60) cover deep guided cases and freehand surgery, with universal compatibility across major implant systems.

Clinical Use Cases

Long Implant Osteotomies
Cases that require more than 15 mm of working depth, including longer implants and demanding bone anatomy.
Deep Guided Cases
Fully guided implant placements where the surgical guide adds height above the osteotomy and longer drills are needed to reach planned depth.
Freehand Implant Surgery
Direct tactile feedback through bone with two carbide drills per site instead of a long steel sequence.
Multi-System Practices
Works across major implant systems so you do not need a separate drill kit per implant brand.

Drill length guide

When 20 mm is the right drill length.

The 20 mm kit exists for cases where 15 mm of working depth does not reach the planned apex. There are three clinical scenarios where the extra length matters, and recognizing them before the procedure starts is what makes the kit choice predictable.

1. Fully guided surgery with a sleeve stack

A typical surgical guide adds 5 to 7 mm above the crestal bone once you account for the guide thickness and the drill shoulder. A 15 mm working length minus a 6 mm guide stack leaves only 9 mm of in-bone reach, which is short of most standard implant lengths. The 20 mm kit restores the full in-bone reach for guided cases regardless of guide thickness.

2. Long implants and full-arch reconstructions

Implants 13 mm and longer (common in posterior mandibular sites, All-on-X protocols, and tilted-implant rehabilitation) require enough drill length to safely reach the planned apex with clearance for the shoulder and stopper. The 20 mm kit is the default for any practice that places long implants regularly.

3. Thick keratinized tissue and deep alveolar anatomy

In sites with thick keratinized gingiva or a deep buccal shelf, the soft-tissue offset alone can consume 3 to 4 mm of drill length before the cortical pass even begins. The 20 mm length keeps the cutting flutes engaged through the full osteotomy rather than the shoulder running against the shank.

If your practice is split between standard and long osteotomies, the 20 mm kit covers both. The drill diameters and the 2-drill protocol are identical to the 15 mm kit, so there is no retraining and no procedural change. Only the apical reach differs.

Compare: 20 mm vs 15 mm

Both kits run the same Crown Down 2-drill protocol with the same solid tungsten carbide drills. The only difference is drill working length.

What clinicians say

5.0(7 reviews)

“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.”
Dr. Henri Diederich
Luxembourg
“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.”
Dr. Ophir Fromovich
Israel
“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.”
Dr. Ernesto Antonio Pichardo Tejada
Dominican Republic
“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.”
Dr. Philippe Bertrand
Montreal, Canada
“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.”
Dr. Ramin Mirmooji
Pierrefonds, Canada
“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
“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.”
Dr. Alberto Miselli, DDS
