CEREC ceramic crowns are clinically comparable to lab-fabricated crowns in strength and longevity – they are made from the same class of materials and fabricated to equally precise digital specifications. The key differences are in the patient experience: no temporary crown that can fail between appointments, no second visit, no waiting one to two weeks for a lab to return the work. For patients who need a crown, the CEREC process is simply faster, more convenient, and eliminates the uncertainty of wearing a temporary restoration.
