Custom Screws Dental Implant Abutment Screw Dentallmplant Parts MillingScrew

1. Manufacturing Process

The production of dental implant screws involves a highly controlled and precise workflow to ensure safety, functionality, and biocompatibility:

1. Material Selection & Bar Cutting
   High-grade titanium or zirconia rods are selected and cut into appropriate lengths for machining.

2. CNC Machining
   Advanced CNC lathes are used to produce the core shape, thread, and connection interface of the implant screw with micron-level precision.

3. Thread Rolling / Milling
   Threads are formed using specialized tools to optimize insertion torque and bone contact.

4. Surface Treatment

   • Sandblasting and Acid Etching (SLA): Increases surface roughness to enhance osseointegration.

   • Anodizing (for titanium): Improves corrosion resistance and color coding.

   • Polishing (for abutments or visible parts): Ensures aesthetic and smooth surfaces.

5. Cleaning & Ultrasonic Degreasing
   Multi-stage ultrasonic cleaning in medical-grade solvents removes any residues or contaminants.

6. Quality Inspection

   • Dimensional inspection using optical comparators or CMM.

   • Surface roughness, hardness, and thread integrity testing.

   • Bioburden and endotoxin testing in certified labs.

7. Laser Marking
   We etch product codes and batch information using medical-grade laser systems to ensure full traceability.

8. Sterile Packaging
   We package the final products in ISO Class 5 cleanrooms and sterilize them using gamma or EO methods.

2. Materials

High-purity and biocompatible materials are used to ensure safety and longevity:

• Titanium Grade 4 – Commercially pure, excellent osseointegration, corrosion-resistant.

• Titanium Grade 5 (Ti-6Al-4V ELI) – Stronger alloy with excellent fatigue strength and biocompatibility.

• Zirconia (ZrO₂) – Used in metal-free implants for better aesthetics in the anterior region.

• Medical-Grade Stainless Steel – Occasionally used for temporary components.
