Seating Accuracy of Prefabricated Interim Crowns on Immediate and Delayed Implants: A Laboratory Study

Prefabricated interim I-Imp crowns suffered from more errors that affected the proximal contact quality than D-Imp crowns. The observed deviation of the I-Imp crowns can be attributed to the socket morphology and its relation to the planned implant position. The deviations of the I-Imp crowns are clinically significant and would require clinical adjustments; therefore, caution is advised when using prefabricated interim crowns on I-Imps.
