Conditions

Badly Decayed Teeth, Teeth Restored With Large Filling Restorations or Endodontically Treated Teeth, Malformed Teeth, Malposed Teeth (Tilted, Over-erupted, Rotated, Etc.) or Spacing Between Posterior Teeth, Single Posterior Crowns

Brief summary

Although the metal-ceramic system is still widely used to fabricate crowns and fixed partial dentures and is considered as the standard treatment in dentistry, aesthetic concerns have stimulated the development of new dental tooth-colored systems as PEEK. BioHPP PEEK is 20% ceramic reinforced, semicrystalline, thermoplastic and radiolucent polymer for extreme durability especially for frameworks for fixed and removable dental prostheses. It has many advantages as low density, light weight, shock absorber, biocompatible and venerable with composite resin. The aim of this study is to evaluate the clinical performance of milled BioHPP PEEK-based single crowns and compare them to metal-based single crowns.
