Milled abutment with cervically applied polyceramic material below its height of contour providing for a gingivally aesthetic restoration is being inserted into the prosthesis.
Prosthesis is facilitating the alignment and seating of the milled abutment.
Prosthesis is being tapped to engage the abutment’s locking taper.
Note the polyceramic material bonded to the abutment below its height of contour. When the prosthesis is cemented with a polyceramic cement the interface will seamlessly achieve a gingivally aesthetic restoration.
Abutment is being definitively tapped to insure the engagement of its locking taper.
A second milled abutment is being placed in the prosthesis for its alignment and seating into the well of the implant.
A third milled abutment is being placed in the prosthesis prior to its alignment and seating into the well of its implant.
Milled abutment being definitively seated.
