Application of PEEK in medical device industry

1. Disadvantages of traditional materials

1. Zirconium dioxide (resin) disc: high hardness, easy to wear the original teeth; high density, uncomfortable to wear

2. Resin porcelain disc: poor temperature resistance, low surface hardness, poor wear resistance, weak antibacterial property

2. Characteristics and advantages of PEEK new materials:

Characteristics and advantages of PEEK new materials
Low density	Elastic modulus similar to human bone
High strength-to-weight ratio	Wear resistance
X-ray transparent	Biocompatible and can be used as implant material
Easy to clean	Low hardness, no damage to original teeth
Corrosion resistance	Can avoid patients’ allergic reaction to metal aluminum alloy
