The Crown Down Drilling Technique

A 2-drill speciality protocol that combines implant site preparation up to 4× faster — with better thermal control, fewer instruments, and predictable primary stability.

What is the Crown Down technique?

The Crown Down technique is a top-down osteotomy protocol that replaces conventional sequential drilling with a 2-drill approach. Instead of using 5–8 drills of increasing diameter (pilot → intermediate → final), the Crown Down method uses one cortical drill and one trabecular drill to prepare the complete implant site.

This is possible because the drills are made from solid tungsten carbide — a material hard enough (~2,600 HV) to cut bone in a single pass at each stage, with thermal conductivity (110 W/m·K) high enough to manage heat without the progressive diameter increases that steel requires.

The 2-drill protocol

Cortical drill

The first drill prepares the cortical bone layer. Tungsten carbide's superior hardness allows efficient cutting through dense cortical bone without the excessive force or heat that steel drills require. Low RPM protocol maintains thermal safety.

Trabecular drill

The second drill shapes the trabecular bone to the final osteotomy dimensions. The crown-down approach — starting from the crestal bone and working apically — preserves bone architecture and provides predictable primary stability.

Why conventional protocols use more drills

Standard implant drilling protocols are designed around the limitations of stainless steel. Because steel dulls quickly and doesn't dissipate heat well, manufacturers compensate by:

Using small incremental diameter increases (0.5mm steps) to reduce force per pass
Requiring copious irrigation to compensate for poor heat dissipation
Mandating frequent drill replacement to maintain acceptable sharpness

The result is a 5–8 drill sequence that works around the material's weaknesses rather than leveraging material strengths. The Crown Down technique starts from a superior material and designs the protocol accordingly.

Clinical advantages

4× Faster site preparation

Two drill changes instead of 4–8. Less instrument management, shorter procedures, more cases per day.

6× Better heat dissipation

Tungsten carbide's 110 W/m·K conductivity actively pulls heat away from bone — far below the 47°C necrosis threshold.

Enhanced Tactile feedback

Clinicians consistently report improved perception of bone density changes during drilling — critical for technique adaptation and primary stability.

Preserved Bone vitality

Lower heat and fewer passes mean less mechanical and thermal trauma to the osteotomy walls — supporting better osseointegration.

A simpler protocol to learn

Most clinicians are comfortable with the Crown Down technique after a single session with the kit. The protocol is simpler than conventional drilling — fewer instruments, fewer steps, and a straightforward cortical → trabecular sequence.

Not just a product — a protocol

The Crown Down technique represents a fundamentally different approach to implant site preparation. It`s not about making a better steel drill — it`s about using a superior material to enable a superior protocol. Fewer drills, less heat, faster procedures, and instruments that never need replacing.

Developed by Dr. Zvi Fudim after decades of clinical practice and materials science research, the Crown Down technique has been used by clinicians internationally with consistent results: cleaner osteotomies, preserved bone vitality, and predictable primary stability.
