All-titanium metal-cut porcelain is a restorative technique that combines a pure titanium metal base with porcelain material. It is widely used in the field of dental restoration. Its advantages are mainly reflected in the following aspects:

1. Excellent Biocompatibility

- Pure titanium is a biocompatible material with minimal irritation to human tissue, and it does not cause allergic reactions or rejection.
- Suitable for patients with metal sensitivities, especially those allergic to nickel-chromium alloys.

2. Lightweight and Comfortable

- Pure titanium has a low density (approximately 4.5 g/cm³), making it lighter than other metals (such as cobalt-chromium alloys). Restorations made from it are comfortable to wear, reducing the burden on the patient's mouth.

3. High Strength and Durability

- Pure titanium has high mechanical strength and can withstand significant biting forces, making it suitable for long-term restorations.
- It has excellent corrosion resistance and oxidation resistance and is not easily eroded by acids and alkalis in the oral environment, resulting in a long service life.

4. High Precision

- All-titanium metal cutting uses CAD/CAM digital processing technology to achieve high-precision restoration fabrication. The marginal fit is excellent, reducing gaps between the restoration and natural teeth, lowering the risk of secondary caries and gingival inflammation.

5. Good Aesthetics

- When combined with porcelain, the pure titanium base can mimic the color and luster of natural teeth, achieving excellent aesthetic results.
- The porcelain layer can be customized in color to meet the patient's aesthetic needs.

6. No Interference with Imaging Examinations

- Pure titanium is radiolucent to X-rays and does not affect imaging examinations such as CT and MRI, facilitating subsequent oral examinations and treatment for the patient.

7. Wide Range of Applications

- All-titanium metal-cut porcelain can be used to fabricate various restorations such as single crowns, bridges, and superstructure for implants, suitable for both anterior and posterior teeth restoration.

8. Environmental Protection

- Pure titanium is a recyclable material, environmentally friendly, and aligns with the sustainable development concept of modern medicine.

Summary

All-titanium metal-cut porcelain combines the excellent properties of pure titanium with the aesthetic effects of porcelain. It offers advantages such as good biocompatibility, high strength, high precision, and strong aesthetics. It is an ideal dental restoration technique, especially suitable for patients sensitive to metals or those seeking high-quality restorations.
