Why do we need titanium plate surface treatment technology?
Although medical titanium plates have excellent biocompatibility, there are still three main problems with untreated surfaces:
1. The surface is too smooth, which is not conducive to the attachment of bone cells
2. It may become a breeding ground for bacteria
3. Long-term use may cause wear
Through professional titanium plate surface treatment technology, it can effectively:
✓ Accelerate bone healing by 30-50%
✓ Significantly reduce the risk of infection
✓ Extend the service life of implants
Comparison of mainstream processing technologies
| Technology name | Processing method | Main advantages | Typical applications |
| Sandblasting acid etching (SLA) | Sandblasting + acid washing | Low cost, promotes bone attachment | Dental implants |
| Anodizing | Electrolytic oxidation | Corrosion-resistant, drug-carrying | Joint prosthesis |
| HA coating | Spraying bone components | Fast bone integration | Patients with osteoporosis |
| Plasma spraying | High-temperature spraying of titanium powder | Porous structure, good stability | Load-bearing parts |
| Antibacterial coating | Adding silver/antibiotics | Good antibacterial effect | Patients at high risk of infection |
Technology Selection Guide
According to different clinical needs, the following are recommended:
- Rapid healing: HA coating + sandblasting, acid etching
- Long-term stability: plasma spraying
- Anti-infection: antibacterial silver ion coating
- Personalized needs: 3D printing + surface treatment
Frequently asked questions
Q: Will the treatment affect the life of the titanium plate?
A: No, it can extend the service life.
Q: Does the 3D-printed titanium plate need to be treated?
A: Yes, usually sandblasting or coating treatment is required.
Q: Which technology works best?
A: There is no best, only the most suitable, and it should be selected according to the specific surgical needs.
Future development trend
Titanium plate surface treatment technology is developing in the direction of intelligence:
Self-healing coating technology
Gene activation coating
Degradable composite coating
Conclusion
Choosing the right titanium plate surface treatment technology is crucial to the success of the operation. It is recommended that patients communicate in detail with the attending physician about the titanium plate processing process before surgery to ensure the best treatment effect.
