Zirconia Restorations: Key Lab‑Side Tips

Zirconia is widely used for crowns, bridges and full‑arch prostheses due to its high flexural strength and biocompatibility. Dental technicians must strictly follow sintering parameters; improper temperature or holding time will cause cracking, chipping or dimensional deviation. Sufficient occlusal reduction is essential before preparation. Thin‑walled zirconia restorations are prone to fracture under heavy bite force. For anterior cases, layered or stained‑glazed techniques can improve natural esthetics. Regular inspection of milling burs also helps reduce remake rates in daily lab production.
