When the provisionalization period ends, a second digital impression is taken with and without the provisional crown, in order to capture the bite, the intraoral position of the zirconia individual abutment, and the status of the soft tissues. (A) The PMMA crown in position after a period of 2 months. (B) The individual hybrid abutment 2 months after placement. The abutment is carefully cleaned by any residual cement particles, the soft tissues are mature and everything is ready for the intraoral digital impression. (C) The first impression of the master model is captured with the functionalized provisional in position, in order to provide the dental technician information on the anatomy of the provisional and its occlusal limits. (D) after the removal of the provisional, the intraoral digital impression of the master model with the abutment in position is captured
