Crown Down 3D Drill Stoppers

The Crown Down 3D drill stopper attaches securely to the drill shank to help control drill position in all three dimensions during guided implant surgery. It works with the Crown Down 2-drill protocol and standard surgical guides for predictable 3-dimensional control during osteotomy preparation. Each Crown Down kit ships with two stoppers (#1 and #2); additional and replacement stoppers are available individually in 8, 10, and 12 mm.

Clinical Use Cases

• Fully Guided Implant Surgery

  Predictable depth and position control during fully guided osteotomy preparation, paired with surgical guides.

• Mixed Workflows

  Add stoppers to the Crown Down 2-drill kit when a specific case calls for guided control on top of the standard freehand workflow.

Clinical context

Why 3-dimensional drill control matters.

Most implant drill stoppers control one axis: apical depth. They prevent over-drilling past the planned implant length, and that is useful. But an implant osteotomy is not a one-dimensional problem. The drill can still drift in angulation and translate in position, and either error puts the implant where the treatment plan did not.

The Crown Down 3D stopper engages the drill shank above the cutting flutes and registers against the surgical guide on a rigid 4 mm tube. That seats the drill in a known position, constrains it to the planned angulation, and bottoms out at the planned apical depth in a single mechanical reference. The result is depth, angulation, and position locked together as one registration event, which is what 3-dimensional control means in this context.

For freehand workflows the stoppers are optional. For any case running a 3D-printed surgical guide, the stoppers turn the guide from a positional reference into a true mechanical envelope around the osteotomy. They are compatible with thermoplastic, SLA, and SLS surgical guides; the only requirement is a guide sleeve sized to receive the 5.5 mm tube.
