Polyetheretherketone (PEEK) scaffolds are high-performance medical materials widely used in the medical field, especially in oral restoration and orthopedic implantation. Their advantages are mainly reflected in the following aspects:

1. Excellent Biocompatibility

- PEEK material has good biocompatibility, high compatibility with human tissues, and is unlikely to cause allergic reactions or rejection, making it suitable for long-term implantation in the body.
- In oral restoration, PEEK scaffolds do not irritate oral tissues, reducing postoperative inflammation and discomfort.

2. High Strength and Stiffness

- PEEK material has excellent mechanical properties, including high compressive strength, high stiffness, and good wear resistance, capable of withstanding considerable bite force and mechanical loads, suitable for supporting and repairing damaged tissues.
- Its strength is close to that of natural teeth, making it suitable for making denture scaffolds and orthopedic implants.

3. Lightweight Design

- PEEK has a low density (approximately 1.3 g/cm³), lighter than metal materials. Scaffolds made from it are comfortable to wear, reducing the burden on patients, especially suitable for large-area restoration.

4. X-ray Transparency

- PEEK material has high X-ray transparency, allowing doctors to observe the implanted site through imaging examinations after surgery, providing accurate diagnostic information.

5. Corrosion Resistance and Heat Resistance

- PEEK has good chemical corrosion resistance, capable of resisting erosion from acidic and alkaline substances in the oral environment, maintaining long-term stability.
- It has excellent heat resistance and maintains stable performance under high-temperature conditions, suitable for various harsh conditions.

6. Easy Processing and Customization

- PEEK material can be precisely processed using CAD/CAM technology to create scaffolds that closely match the patient's oral morphology, improving fit and comfort.
- Its excellent processing properties support various processes such as injection molding, extrusion, and cutting, meeting individual needs.

7. Aesthetics

- PEEK material has a certain degree of transparency, allowing it to naturally integrate with surrounding tissues, enhancing the aesthetics of the restoration.

8. Antibacterial Properties

- PEEK material has certain antibacterial properties, reducing the growth of oral bacteria and lowering the risk of infection.

Summary

Polyetheretherketone scaffolds, with their excellent biocompatibility, high strength, lightweight design, X-ray transparency, and easy processability, have become an important material in the medical field. Although the cost is relatively high, through reasonable design and application, it can provide patients with high-quality restoration effects and a comfortable experience.
