August 2-8, 201020 Implant Tribune United Kingdom Edition temporary on the implant and a temporary crown for 11 were made using a temporary abut- ment. The temporaries were fit- ted (Fig 13); conditioning of the soft tissue began one week later with application of composite to the cervical region of the implant temporary. After conditioning three times, the desired emer- gence profile was achieved (Figs 14-15). For the final impression, an impression post was custom- ized with composite so that it corresponded to the emergence profile of the temporary (Fig 16). After taking an impression with polyether a model was made that reproduced the gin- gival conditions perfectly. The patient, dental technician and dentist had agreed to carry out all-ceramic reconstruction with the Straumann® CADCAM sys- tem. The “Wax Up Design” func- tion of the CADCAM etkon™ visual software allows wax pat- terns to be scanned and zirco- nium oxide frameworks to be produced that optimally support the veneering porcelain. First, a try-in wax-up was made from resin and tried in the patient; minor esthetic corrections were made. Using a silicon index of the wax-up, the frameworks for crown 11 and the directly screwed implant crown 21 were formed from scannable wax (Fig 17). The modelled frameworks were placed in the 3D scanner and scanned (Fig 18). These data were then sent via the Internet to the milling center. Three days later the frameworks arrived in the laboratory and the accuracy of fit was checked on the model. page 19DTß Fig 5 Fig 6 Fig 7 Fig 8 Fig 13 Fig 9 Fig 14 Fig 15 Fig 16 Fig 10 Fig 13 Fig 12 page 22DTà
