18 For the impression taking and bite registra- tion we used the multifunctional cap that is mounted on the implant base precise- ly and which is secured against rotating. During the impression taking, ensure that the retentions on the multifunctional cap are filled with impression material. This en- sures that the multifunctional cap is held securely in the impression material and the implant position can be transferred to the model with a high degree of precision (Fig. 14 and 15) . The bite registration is done in the standard intercuspation position. To do this, another multifunctional cap (each iSy implant in- cludes two multifunctional caps) is short- ened on the basis of the occlusal situa- tion and the bite registration is performed using the Shimstock protocol (Fig. 16 and 17) . Soft tissue conditioning and pros- thetic restoration To condition the soft tissue in accordance with the planned emergence profile, the gingiva former was modified extraorally with composite material and reinserted (Fig. 18 to 22) . The initial slight anemia disappeared after a few minutes and the soft tissue subsequently looked very good. The modified gingiva former is replaced after about two weeks with a long-term temporary restoration (Fig. 23 to 27) . The final restoration of zirconium oxide ce- ramic is then attached (Fig. 28 to 33) . I would like to thank MDT Verena Grumber, Weilheim, for her assistance with the den- tal technician aspects of this case. Fig. 14: The multifunctional cap is mounted on the implant base.
