What this means for you

Real risk of harm even if no illness or injury has been reported yet. Stop using the product and follow the agency's guidance.

Our severity reasoning: This is a risk-of-harm product where defective dental blocks may cause fractures in patients' mouths. The FDA Class II classification and lack of any reported illnesses or injuries to date support a High severity rating per the rubric criterion for risk-of-harm products where injury has not yet been reported.

Plain-English summary

IVOCLAR VIVADENT AG is recalling 2,472 units of IPS e.max ZirCAD CER/in. Prime C2 C17/5 zirconium oxide blocks. These dental material blocks are used by dentists and dental laboratories to fabricate fixed dental restorations (crowns and bridges) for both front and back teeth. The product was distributed nationwide in the United States.

Defective blocks may develop cracks during the sintering process, which is the high-temperature firing that hardens the material. If these cracks are not detected before use, the resulting dental restorations may fracture in the patient's mouth, requiring additional restoration work.
