COMPLEX CASE: Quadrant replacement with dental implants Fig. 19 Fig. 22 Fig. 23 Fig. 20 Fig. 21 implant-supported fixed dental prosthesis (8/X/6) and two implant-supported crowns (#5 and #4). We also discussed the options for tooth #3, which had supraerupted into the opposing edentulous site. The patient opted to not have anything done and attempt to preserve the existing crown on that tooth. Photographs, intraoral scan and CBCT were taken, allowing for virtual implant treatment planning based on the desired prosthetic outcomes (Figs. 14 and 15). A fully guided 3D-printed surgical stent (Fig. 16) and a milled TempShell were fabricated (Fig. 17). 68 JUNE 2019 // dentaltown.com The bridge and cantilevered pontic were sectioned off and the teeth were extracted atraumatically. Implants were placed using the appropriate guided surgical protocols. Initially, primary stability greater than 35NCm was achieved (Figs. 18-20), which allowed for utilizing the TempShell to fabricate an immediate provisional bridge (Fig. 21). The provisional bridge emergence profiles and pontic sites were modified and contoured to allow for ideal tissue reaction and adaptation. Sixteen weeks later, implant integration was verified and final impressions were taken using an intraoral scanner. The intraoral scanner allowed us to capture the provisionals and the soft-tissue emergence profile once the provisionals were removed (Fig. 22), then to utilize scan bodies to capture the position of the implants (Fig. 23). The scan also captured the occlusal vertical dimension, jaw relationship record, and shade of the provisional bridge and adjacenthttp://www.dentaltown.com
