The full Crown Down 2-drill protocol in a 15 mm-length tungsten carbide kit, sized for standard implant osteotomies.
The Crown Down 15 mm implant drilling kit replaces a long steel drill sequence with two solid tungsten carbide drills per implant site. Eight drill diameters from Ø 2.75 mm (#20) to Ø 6.0 mm (#60) cover the full range of standard implant osteotomies for guided and freehand surgery, with universal compatibility across major implant systems.
Day-to-day implant placement where 15 mm of working depth is sufficient for the planned osteotomy.
Direct tactile feedback through bone with two carbide drills per site instead of a long steel sequence.
Pairs with surgical guides and Crown Down 3D stoppers for predictable depth and position control.
Works across major implant systems so you do not need a separate drill kit per implant brand.
Drill length guide
The 15 mm kit is the daily-driver length for general implant placement. For most posterior maxillary and mandibular cases, 15 mm of working depth comfortably covers the implant apex with room to spare on the drill shoulder and the stopper. If your case mix is primarily single and short-span implants, this is the kit that earns its place on the tray.
1. Standard posterior and anterior osteotomies
Implants in the 8 to 12 mm range, placed freehand or with a thin surgical guide, fit comfortably within 15 mm of drill reach. The shoulder rides above the cortical plate and the stopper engages cleanly without forcing the flutes past their cutting depth.
2. Sinus-aware maxillary placements
In posterior maxillary sites near the sinus floor, planned implant lengths are intentionally bounded by the residual ridge height. A 15 mm working length keeps the drill apex within the planned osteotomy envelope and avoids over- reach into anatomy you actively want to preserve.
3. Freehand surgery and thin guides
Without a surgical guide adding 5 to 7 mm above the bone, the full 15 mm working length translates directly to in- bone reach. This is the right kit for clinicians who run a freehand workflow or use thermoplastic positioning guides rather than a full sleeve stack.
If your practice runs deep guided cases or All-on-X rehabilitations regularly, the 20 mm kit covers those scenarios. Otherwise, the 15 mm kit handles the vast majority of routine implant placements with the same 2-drill protocol and the same solid tungsten carbide drills.
Both kits run the same Crown Down 2-drill protocol with the same solid tungsten carbide drills. The only difference is drill working length.

“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

“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 Framovich
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

“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

“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.”
