Category 96 Australasian Dentist Prosthetic procedure After the implant placement, the temporary abutment (Temporary Abutment Crown; Institut Straumann AG) was secured on the implant with 15 Ncm torque. The 3D-printed provisional crown was adjusted to ensure the complete seating over the temporary abutment. Autopolymerizing resin was used to lute the provisional crown to the temporary abutment. The temporary crown was then removed from the implant. It was adjusted and polished in a dental laboratory. Light- polymerizing clear coating was used to protect the provisional crown (Figs. 20-24). After two months of uneventful healing, the patient returned for the final impression with an intraoral scanner (Virtuo Vivo™; Institut Straumann AG). Scanbody (Mono Scanbody; Institut Straumann AG) was secured to the implant with 15 Ncm of torque. The intraoral scans and virtual occlusal record were exported in a polygon file format (PLY) and imported into a CADCAM software program (CARES ® Visual; Institut Straumann AG) in order to design the definitive restoration on a prefabricated abutment (Variobase ® Crown; Institut Straumann AG). The definitive crown was milled with a multi- layered ultra-high translucent zirconia (zerion ® UTML; Institut Straumann AG). Surface characterization and glazing were completed on the definitive zirconia crown. The crown was luted to the prefabricated abutment with a resin luting agent. The patient returned to the clinic for the definitive crown delivery. After the conformation with aesthetic and functional outcomes intraorally, the definitive crown was secured to the implant with 35 Ncm. Teflon and light- polymerizing composite resin were used to seal the screw access (Figs. 25-30). clinical Fig. 25 Occlusal view 2 months after procedure Fig. 27 Final crown – lab aspect – buccal view Fig. 29 Final restoration – Occlusal view Fig. 26 Final crown – lab aspect – occlusal view Fig. 28 Final restoration – Buccal view Fig. 30 Final periapical radiograph Treatment outcomes Overall, the immediate placement and loading approach was utilized for this clinical treatment with the aid of digital data recording, surgical planning, computer-guided surgery, and CADCAM provisional and definitive restorations. The newly designed Straumann ® TLX Implant System with fully tapered Tissue Level implants (TLX) was used to achieve high primary stability and immediate placement procedures. The Roxolid ® implant with the SLActive ® surface provided the clinician with a predictable outcome with reduced healing time and shorter treatment time overall. The patient was satisfied with the immediate treatment approach and the aesthetics and functional outcomes associated with this clinical treatment. u 1800 806 450 www.amalgadent.com.au Gives us 5 BISCO Every Adhesive has 1 good reason SEE BACK COVER ABU Footer #90.indd 1 25-Aug-21 4:43:51 PM
