Comparative Evaluation of Antagonistic Tooth Wear After Placement of Crowns Made From Three Different Materials Using a Digital Intraoral Scanner: An In Vivo Study.

Researchers compared how much opposing natural molars wore down against crowns made from three different materials over 12 months using digital scanning. PEEK crowns caused the least wear to opposing teeth, followed by zirconia, while DMLS crowns produced the most wear.
