13 CASE STUDY Fig. 23: In the abutment design program, the anato- mically contoured subgingival areas were checked. Fig. 24: Before uploading the abutment onto Dental Manager, the machinability was checked in the image of the preform. Fig. 25: The DEDICAM titanium abutments supplied were screwed onto the model and the position of the abutment shoulders was checked. We cemented the implant-supported zir- conia crowns and bridges and the IPS e.max ® CAD crowns with dual-cure, semi- permanent Harvard luting cement and the zirconia bridges on natural teeth with glass ionomer luting cement from 3M Espe (Ketac ® Cem). Due to the optimal posi- tioning of the crown-abutment transitions, the cement excesses could be easily and precisely removed. After another check of the occlusion and function, we took im- pressions to prepare an occlusal splint for protection at night. Conclusion In complex clinical situations, preparing a comprehensive treatment concept as well as good and expert technical communica- tion between all parties is essential for a functional and esthetic restoration that is stable over the long term. An immobile, attached and possibly keratinized gingiva around the implant penetration point pro- tects against bone loss and ensures natu- ral red and white esthetics. In the surgical phase, it must be ensured that tension due to cheek ligaments and mobile mucosa in Fig. 29: The basal gingival support for the pontics was anatomically shaped. Pseudopapillae formed between the anterior teeth. Fig. 30: The monolithic occlusal surfaces and palatal parts of the zirconia bridges were individually stained. Fig. 31: The photograph shows the precise transition from the highly polished subgingival parts of the DEDICAM titanium abutments to the zirconia crowns. Fig. 32: The individual subgingival design of the DEDICAM abutments integrates into the contoured soft tissue without exerting any pressure. Fig. 33: The zirconia bridges and full ceramic crowns were cemented. Excess cement was easy to remove because of the optimal positioning of the crown-abutment transitions.
