What it is

Dental implants need abutments. Orthopedic surgery needs bone screws. Both start as precision rod.

Dental implant titanium abutment orthopedic bone screw is the raw material for both. Same grade. Same tolerances. Same surface finish. Different diameters. Different lengths.

The rod goes into a Swiss lathe. Gets machined into an abutment or a screw. Threads rolled. Head formed. Surface treated.

Two applications, one material

Dental abutment. Goes on top of the implant fixture. Supports the crown. 2.0mm to 5.0mm diameter. Grade 23 ELI or Grade 5. High strength. Small size.

Orthopedic bone screw. Goes into bone. Holds plates. Fixes fractures. 1.5mm to 8.0mm diameter. Grade 23 ELI for load-bearing. Grade 4 CP for non-load-bearing.

Same material family. Same precision requirements. Same biocompatibility needs.

For dental implant titanium abutment orthopedic bone screw, the bar stock is interchangeable. One rod can become either part.

Which grade for which application

Grade	Material	Tensile	Best for
Grade 23 ELI	Ti-6Al-4V	860 MPa	Dental abutments, load-bearing bone screws
Grade 5	Ti-6Al-4V	895 MPa	Commercial grade. Some dental applications
Grade 4 CP	Pure titanium	550 MPa	Non-load-bearing bone screws, cortical screws

Grade 23 ELI is medical grade. ASTM F136. Lower oxygen. Higher toughness. Better fatigue life. Used for both dental abutments and orthopedic screws.

Grade 5 is commercial grade. ASTM B348. Not for implants. Some dental labs use it for non-implant parts. We don't recommend for surgical use.

Grade 4 CP is pure titanium. No aluminum. No vanadium. Used for bone screws in low-stress applications.

For dental implant titanium abutment orthopedic bone screw, Grade 23 ELI is the standard for implantable parts.

Common diameters

Diameter (mm)	Application
1.5 – 2.0	Small bone screw (hand, foot)
2.0 – 2.5	Dental abutment screw
2.5 – 3.0	Dental abutment blank (small)
3.0 – 3.5	Bone screw (wrist, ankle)
3.5 – 4.0	Dental abutment (standard)
4.0 – 5.0	Bone screw (hip, knee)
5.0 – 6.0	Large bone screw (femur)
6.0 – 8.0	Custom abutment, large screw

Dental implant abutment

The abutment connects the implant fixture to the crown. Sits above the gum line. Visible in the patient's mouth.

Precision is critical. The abutment must fit the implant exactly. Internal hex or octagon. Tapered connection.

The rod is machined into the abutment shape. External hex. Screw hole down the middle. Polished surface.

For dental implant titanium abutment orthopedic bone screw, abutments use the same rod as bone screws. Same precision. Same material.

Orthopedic bone screw

The bone screw holds plates to bone. Or fixes fractures directly. Cortical screw. Cancellous screw. Locking screw.

Threads are rolled, not cut. Rolling compresses the metal. Increases fatigue strength. Better than cutting.

Head styles. Hexalobular (Torx). Hex drive. Phillips. Cross. Flat.

For dental implant titanium abutment orthopedic bone screw, bone screws need high strength and good fatigue life. Grade 23 ELI delivers both.

Why same rod works for both

Dental abutments and bone screws have similar requirements:

Small diameter. High precision. Smooth surface. Biocompatible material. No nickel. Good machinability.

A 4.0mm rod can become a dental abutment for a molar. Same 4.0mm rod can become a bone screw for an ankle.

Same material. Same supplier. Same quality system. Easier procurement.

For dental implant titanium abutment orthopedic bone screw, one rod serves two markets.

Surface finish

Both applications need smooth surface. Tissue contact. No irritation.

Polished. Ra ≤ 0.2μm. Standard for both.

Electropolished available. Ra ≤ 0.05μm. For high-end dental abutments.

Machining considerations

Swiss lathe. High speed. Small diameter. Tight tolerances.

For dental implant titanium abutment orthopedic bone screw, the rod needs consistent diameter. ±0.025mm tolerance. No surface defects. No burrs.

We supply rod ready for your Swiss machine.

Thread rolling

Threads are rolled, not cut. Rolling requires consistent rod diameter.

Diameter tolerance	Effect
±0.025mm	Excellent rolling, consistent threads
±0.05mm	Acceptable, occasional adjustment
±0.10mm	Poor rolling, thread variation

We hold ±0.025mm. Thread rolling runs smoothly.
