Low-friction glide
Coefficient of friction approximately 0.1 — about a quarter of standard surgical stainless steel. The osteotome glides into cortical and dense bone instead of fighting against it.

DLC-Coated Osteotomes · five inserts for crestal preparation and osseodensification
Five DLC-coated osteotomes — Black Ruby 1 through 5 — engineered for low-friction crestal preparation and osseodensification with the Magnetic Mallet. The diamond-like carbon coating reduces the coefficient of friction so the osteotome glides into dense bone (D2/D3) instead of fighting against it, while the magnetodynamic impulse delivers controlled force without manual mallet strikes.

Black Ruby
in motion
A short introduction to Black Ruby — the DLC-coated osteotomes and the magnetodynamic principle behind low-friction osseodensification.
01 The clinical problem
Rotary drills
remove the bone we want to preserve
Conventional implant site preparation uses rotary cutting drills that remove bone — including the crestal cortex that contributes to primary stability. In soft maxillary bone (D3–D4), narrow alveolar ridges, and post-extraction sockets, drilling can compromise the bone available for osseointegration and the alveolar architecture surrounding the implant.
Heat is generated, irrigation is required, the surgical field becomes wet, and bone shavings are simultaneously removed and lost. Osseodensification — an established approach that compacts bone instead of cutting it — depends on a smooth, progressive advance of an osteotome that is calibrated, low-friction, and operator-independent.
02 The Black Ruby approach
DLC coating + magnetodynamic impulse
compact bone instead of cutting it
Black Ruby osteotomes are coated with diamond-like carbon (DLC) — an industrial-grade hard coating with a coefficient of friction approximately a quarter of standard surgical stainless steel. The osteotome glides into cortical and dense bone instead of fighting against it. Heat generation drops, tactile feedback becomes predictable, and the bone gets compacted in a controlled progressive way.
Combined with the Magnetic Mallet, force is delivered by the device in a 50-microsecond impulse — no manual mallet strikes, no operator fatigue, no variable pressure. Five osteotomes (BR1 through BR5) cover the standard rotary bur-free implant site preparation sequence, from initial pilot to final preparation, with the same low-friction glide at every step.
02 Six benefits
Six benefits
of DLC-coated osteotomes
Five Black Ruby osteotomes. One controlled magnetodynamic impulse. Friction reduced by design — so bone gets compacted, not removed.
True osseodensification
Bone is compacted, not cut. The crestal cortex is preserved and the peri-implant bone density typically increases — ready for immediate or staged implant placement.
No manual mallet strikes
The Magnetic Mallet delivers a 50-microsecond magnetodynamic impulse — calibrated, constant, operator-independent. No fatigue, no variable pressure, no auditory shock for the patient.
Reduced heat at the osteotomy
Lower friction means lower heat at the bone-instrument interface. Reduced risk of thermal stress in long crestal preparations and dense D2/D3 bone.
Five sizes, one workflow
Black Ruby 1 to 5 cover the standard osseodensification sequence — from initial pilot to final preparation — with the same DLC-coated surface at every step.
Pairs with Kit Elevate
Black Ruby integrates with the Kit Elevate workflow for crestal sinus floor elevation: progressive bone densification followed by atraumatic membrane lift in a single magnetodynamic protocol.

03 The Surgical Kit · Five osteotomes
Five osteotomes
one progressive sequence
From initial pilot to final preparation — five DLC-coated osteotomes that share the same low-friction surface and the same magnetodynamic impulse delivery. Available in Straight (anterior) and Curved (posterior) versions.
Black Ruby 1
Sets the osteotomy axis with a controlled magnetodynamic impulse — the foundation for the rest of the sequence.
Black Ruby 2
Continues the preparation with the next step in the standard osseodensification protocol — gradual enlargement and densification.
Black Ruby 3
Full-length preparation — DLC coating supports a low-friction advancement through dense bone, compacting cortex without removing it.
Black Ruby 4
Final shape of the crestal portion of the osteotomy for optimal implant emergence profile.
Black Ruby 5
Last osteotome of the sequence when the implant diameter requires an additional preparation step (5 mm+ implants).
Each osteotome is available in Straight (anterior sectors) and Curved (posterior sectors) versions. Laser-etched depth marks at approximately 4.8 mm, 5.2 mm, and 7 mm provide immediate visual reference. Surgical stainless steel with diamond-like carbon (DLC) coating, fully autoclavable. Power levels 1–2 of 4 commonly used; level 3 in selected cases.

Black Ruby + Kit Elevate
one crestal protocol
Black Ruby and Kit Elevate are designed to work together as a two-step crestal sinus lift workflow — progressive bone densification followed by atraumatic Schneiderian membrane elevation. Same Magnetic Mallet handpiece, same magnetodynamic impulse, same low-friction principle from start to finish.
STEP 01
Black Ruby
Densify the bone
Five DLC-coated osteotomes (BR1 → BR5) progressively densify the crestal bone toward the sinus floor. The DLC coating glides through dense D2/D3 bone, the magnetodynamic impulse delivers controlled force, and the peri-implant bone density typically increases.
STEP 02
Kit Elevate
Lift the membrane
Five concave-tipped osteotomes with millimeter-level stops from 1 to 13 mm gently elevate the Schneiderian membrane through hydraulic pressure. No rotary burs, no irrigation in the sinus, no manual mallet strikes.

07 Frequently asked questions
Common questions
about Black Ruby
What is Black Ruby and what is it used for?
Black Ruby is a kit of five DLC-coated osteotomes designed for the OSSEOTOUCH Magnetic Mallet. It performs low-friction crestal preparation, osseodensification, rotary bur-free implant site preparation, immediate post-extraction implants, moderate crestal sinus lift (3–6 mm), and split crest expansion of narrow ridges.
What is DLC coating and why does it matter?
DLC stands for diamond-like carbon — an industrial-grade hard coating with a coefficient of friction of approximately 0.1, about a quarter of standard surgical stainless steel. The osteotome glides into cortical and dense bone instead of fighting against it, generating less heat and delivering more predictable tactile feedback to the surgeon.
How does Black Ruby compare to traditional Summers osteotomes?
Summers osteotomes rely on the surgeon striking a manual mallet to advance the instrument — variable force, fatigue-sensitive, auditorily disturbing. Black Ruby works with the Magnetic Mallet impulse: calibrated, constant, operator-independent. The DLC coating reduces friction by approximately 75% compared with uncoated steel.
How does Black Ruby compare to rotary osseodensification burs?
Rotary osseodensification burs perform bone densification through rotary motion at high speed, requiring constant irrigation. Black Ruby achieves bone densification through a percussive magnetodynamic impulse — no rotation, no irrigation during densification, no rotary handpiece noise. Both share the principle of compacting bone rather than removing it.
What is osseodensification and why is it important?
Osseodensification is a bone preparation technique that compacts bone around the osteotomy site instead of removing it. The crestal cortex is preserved, peri-implant bone density typically increases, and primary implant stability improves. Particularly valuable in soft maxillary bone (D3-D4) and narrow ridges where conventional drilling can compromise primary stability.
Can Black Ruby be used for crestal sinus lift?
Yes. A moderate crestal sinus lift (3–6 mm) is one of the standard Black Ruby protocols. The osteotome creates a greenstick fracture of the sinus floor and the Schneiderian membrane tents over the prepared site. Often possible without biomaterial, using autologous condensed bone and the blood clot. For larger lifts, pair with Kit Elevate.
At what power level should Black Ruby be used?
Power levels 1–2 of 4 are used in approximately 90% of Black Ruby procedures. Higher levels are reserved for particularly dense bone (D1-D2 cortex) or final coronal refinement. The 50-microsecond impulse is below the threshold typically perceived as vibration.
What is the FDA regulatory status of the Magnetic Mallet system?
The OSSEOTOUCH Magnetic Mallet is listed under FDA product code GEY (Class I surgical instrument motor/accessory, 21 CFR 878.4820), 510(k)-exempt and subject to general controls. Black Ruby osteotomes fit new-generation Magnetic Mallet handpieces and are fully autoclavable.
