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
