Orthopedic and dental implantsParts for every
area of the skeleton.

Set screw. Small headless screw with a hex socket, threaded into the internal thread of the tulip. Tightened to torque, it presses the connecting rod against the screw head and locks the angle chosen by the surgeon. Material: Titanium Ti-6Al-4V ELI (3.7165) · ASTM F136 / ISO 5832-3. Typical process: Swiss-type turning, external thread, hex socket. On this model: Ø 9 mm, height 5 mm.

Connecting rod. Cylindrical rod that links the screws of several vertebrae. The surgeon bends it in the operating room to follow the curvature of the spine, then clamps it in each tulip. Material: Titanium Ti-6Al-4V ELI (3.7165) · ASTM F136 / ISO 5832-3 or ISO 5832-9 stainless steel (M30NW) · ASTM F1586. Typical process: Turning, then bending. On this model: Ø 5.5 mm.

Polyaxial head (tulip). U-shaped part that caps the spherical head of the screw. It pivots in every direction before tightening, so the rod can be aligned even when the screws are not parallel. Its internal thread receives the set screw. Material: Titanium Ti-6Al-4V ELI (3.7165) · ASTM F136 / ISO 5832-3. Typical process: Mill-turning: U-slot, internal thread, spherical seat. On this model: Ø 12 mm, 5.7 mm slot.

Pedicle screw. Coarse-thread screw that passes through the pedicle, the bony bridge at the back of the vertebra, into the vertebral body. Its spherical head fits into the tulip. Material: Titanium Ti-6Al-4V ELI (3.7165) · ASTM F136 / ISO 5832-3. Typical process: Swiss-type turning, thread whirling, socket in the head. On this model: Ø 6.5 × 45 mm.

Pedicle screws. Each vertebra receives two screws, one per pedicle. They converge slightly toward the center of the vertebral body, where the bone is strongest. Material: Titanium Ti-6Al-4V ELI (3.7165) · ASTM F136 / ISO 5832-3. Typical process: Swiss-type turning, thread whirling. On this model: Ø 6.5 × 45 mm.

Polyaxial heads. Each tulip swivels on its screw so the rod runs straight from one vertebra to the next, even if the screws are not at the same angle. Material: Titanium Ti-6Al-4V ELI (3.7165) · ASTM F136 / ISO 5832-3. Typical process: Mill-turning, internal thread.

Set screws. Once the rod is in place, a set screw is tightened in each tulip. The construct becomes rigid and holds the two vertebrae still while they fuse. Material: Titanium Ti-6Al-4V ELI (3.7165) · ASTM F136 / ISO 5832-3. Typical process: Swiss-type turning, hex socket.

Connecting rods. Two rods, left and right, link the screws of the two vertebrae. They carry the loads during bone fusion. Material: Titanium Ti-6Al-4V ELI (3.7165) · ASTM F136 / ISO 5832-3 or ISO 5832-9 stainless steel (M30NW) · ASTM F1586. Typical process: Turning, then bending. On this model: Ø 5.5 mm.

Interbody cage. Placed between the two vertebral bodies in place of the disc, it restores the height between the vertebrae. Its windows are packed with bone graft: bone grows through them and fuses the two vertebrae. In the neck, the same part is called a cervical cage. Material: PEEK · ASTM F2026 or Titanium Ti-6Al-4V ELI (3.7165) · ASTM F136 / ISO 5832-3. Typical process: Milling, graft windows, anti-migration teeth. On this model: 11 × 30 mm.

Cervical cage. Small cage inserted through the front of the neck between two vertebrae, in place of the damaged disc that was compressing a nerve or the spinal cord. It restores disc height; its teeth prevent it from backing out, and its central window receives the bone graft. Material: PEEK · ASTM F2026 or Titanium Ti-6Al-4V ELI (3.7165) · ASTM F136 / ISO 5832-3. Typical process: Milling: teeth, graft window, marker holes. On this model: 14 × 12 mm, height 7 mm.

Bone graft. Patient bone or bone substitute packed into the cage window. Within a few months, the two vertebrae fuse through it: this is arthrodesis. Nature: Patient bone or substitute, not a machined part.

Radiopaque markers. PEEK is invisible to X-rays. These small metal pins, press-fitted into the cage, let the surgeon check its position on follow-up X-rays. Material: Tantalum · ASTM F560. Typical process: Precision holes drilled in the cage for press-fitting. On this model: Ø 1 × 3.2 mm, 3 markers.

Headless screw. Cannulated screw with a dual thread: the pitch is longer at the tip than at the back. As it is driven in, it draws the two fragments together and compresses them, with no head protruding from the bone. It is placed over a guide wire that runs through its central canal. Material: Titanium Ti-6Al-4V ELI (3.7165) · ASTM F136 / ISO 5832-3. Color coding: Size-coded color anodizing. On this model: Ø 3.5 / 4 mm, length 21 mm, 1.0 mm pitch at the tip and 0.8 mm at the back, Ø 1.1 mm cannulation.

Fracture line. The scaphoid often breaks in a fall on the hand. Poorly vascularized, it heals slowly: the compression provided by the screw promotes healing.

Mini plate. Plate barely more than one millimeter thick, placed on the back of the bone. It keeps the fragments aligned during healing without interfering with the tendons gliding just above. Material: Titanium Ti-6Al-4V ELI (3.7165) · ASTM F136 / ISO 5832-3. Typical process: High-speed milling, countersunk holes. On this model: 40 × 6 × 1.3 mm, 4 holes.

Ø 2 mm plate screw. Very small-diameter screw whose conical head seats in the plate. One anodizing color per length helps the surgical team pick the right screw. Material: Titanium Ti-6Al-4V ELI (3.7165) · ASTM F136 / ISO 5832-3. Equipment: Chiron FZ 08K S Magnum, 30,000 rpm (±3 µm). On this model: Ø 2 mm, 4 screws.

Fracture line. The fracture line is not a machined part. It shows what the plate and screws hold in place while the bone rebuilds.

Compression screw. Only the tip is threaded: as it is tightened, the head pulls the near fragment against the far fragment and closes the osteotomy line. Two screws keep the fragments from rotating. Material: Titanium Ti-6Al-4V ELI (3.7165) · ASTM F136 / ISO 5832-3. Color coding: Size-coded color anodizing. On this model: Ø 3 mm, partial thread.

Osteotomy. To correct a hallux valgus, the surgeon cuts the metatarsal at an angle and shifts the fragment. The screws hold the new position while the bone heals.

Crown. The visible part of the tooth, custom-made by the dental technician in ceramic or zirconia. It is screwed or cemented onto the abutment. Material: Ceramic or zirconia. Manufacturing: Dental technician, not machined by us.

Abutment. Intermediate part that emerges from the gum and carries the crown. Its hexagonal base fits into the implant so it cannot rotate. Material: Titanium Ti-6Al-4V ELI (3.7165) · ASTM F136 / ISO 5832-3. Typical process: Mill-turning, hexagon, taper of the transmucosal section. On this model: Height 7.6 mm.

Abutment screw. It passes inside the abutment and threads into the bottom of the implant. Tightened to torque, it seats the abutment on the implant with no play. Material: Titanium Ti-6Al-4V ELI (3.7165) · ASTM F136 / ISO 5832-3. Typical process: Mill-turning, M1.6 thread, drive recess. On this model: Overall length 10 mm, M1.6.

Implant. Titanium screw placed in the jawbone. Within a few months, the bone bonds to its surface: this is osseointegration. Its internal thread receives the abutment screw. Material: Titanium grade 4 · ASTM F67 / ISO 5832-2 or Titanium Ti-6Al-4V ELI (3.7165) · ASTM F136 / ISO 5832-3. Typical process: Mill-turning, external thread, internal connection. On this model: Ø 4.1 × 10.6 mm.
