IVOCLAR VIVADENT AG is recalling 7,445 units of IPS e.max ZirCAD CER/in. Prime zirconium oxide blocks because they may crack during sintering, potentially causing dental restorations to fracture in patients' mouths.
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: Class II medical device recall for a structural defect in a dental component that could cause patient harm if undetected. No illnesses or injuries have been reported. The risk-of-harm nature of the product with no reported injury meets the criterion for High severity.
Plain-English summary
IVOCLAR VIVADENT AG is recalling 7,445 units of IPS e.max ZirCAD CER/in. Prime A1 C17/5 zirconium oxide blocks distributed nationwide. These blocks are used by dental professionals to fabricate fixed, full-contour restorations (such as crowns) for anterior and posterior teeth.
Defective blocks may develop cracks during the sintering process, which is the high-temperature heating used to harden the dental material. If these cracks are not detected before the restoration is placed in a patient's mouth, the restoration may fracture during use, requiring additional dental treatment.
Dental laboratories and dentists using the affected batch numbers (Z067J5, Z067J6, Z06CBD, Z06CBF) should stop using these blocks immediately. Any restorations already fabricated from these blocks should be inspected for visible defects before being delivered to patients.
Patients who have received restorations made from affected blocks should contact their dentist if they experience cracking, fracturing, or other problems with their restorations.
