Key Differences Between PFM And All-Ceramic Dental Crowns

PFM crowns and all-ceramic crowns differ in materials, aesthetics, applicability, and performance. PFM crowns have a metal inner layer and a ceramic outer layer, while all-ceramic crowns are made entirely of ceramic. Over time, PFM crowns may cause gingival staining, while all-ceramic crowns maintain natural aesthetics. PFM crowns are suitable for posterior teeth, while all-ceramic crowns excel in anterior restorations. PFM crowns are harder but brittle, while all-ceramic crowns are tough and preserve more tooth tissue. Both require similar production steps, but all-ceramic crowns have higher technical requirements. When choosing, consider oral condition, needs, and budget. Regular maintenance is crucial for both types.
