Thank you all for your comments. I inherited this case after a failed PFM restoration from another lab. 6 implant abutments in the front were fixed, and in order to build a monolithic zr bridge, the only option left was to incorporate it with screw channel design as workability was very limited. Prior to final milling of the bridge, the functional and aesthetics analysis was performed with wax try-in, and vertical dimension, overjet, midline and incisal edge position, and smile line etc. were verified and approved by the doctor and the patient. As you may all know, 100 % zirconia restoration would not look as nice as good porcelain work, however, considering this bridge is 100% ZR and no addition of porcelain powder, it turned out very well, IMHO. And this ZR bridge will not chip or break. Thank you again for your comments, and I’ll post an update later.
