There is nothing quite like the satisfaction of seating a case successfully without the need for time-consuming adjustments. Conversely, it can be very frustrating for the clinician and the patient when things don’t go smoothly. Perhaps a restoration fails to seat correctly or needs such significant adjustments that it must be returned to the lab for refinishing or entirely remaking. Poor impressions and incorrect shades are two of the most common failures resulting in remakes and adjustments, and there are many others.
The introduction of stronger and more durable ceramics over the past few years has greatly increased the clinician’s choice of materials when fabricating an all-ceramic three unit bridge. The latest generation of zirconia is suitable for three unit bridges and can restore teeth anywhere in the mouth, and IPS e.max is suitable for anterior teeth.
