Prosthetic procedure At the end of the same day, the healing abutment was replaced by the provisional restoration (Figure 2c ). The provisional consisted of a screw-retained, platform switched titanium stock abutment with an acrylic resin crown. The crown was under-contoured to allow the gingiva to regrow for better aesthetics at final crown stage. The temporary crown was torqued to 25Ncm and left to heal for 3 months. It was checked that there was no contact with antagonistic teeth during articulation. A CBCT was made to check the correct implant position ( Figure 4a ). Figure 3. Straumann BLX implant RB.
