I 15 case report _ digital solutions in implantology I CAD/CAM 3_2014 The dental model was produced by Innovation MediTech after online transfer via Straumann CARES based on the STL files. Then the appropriate repositionable Straumann Regular Neck implant analogue was placed in region 46 (Figs. 9 & 10). In parallel, the planned abutment, customised via Straumann CARES X-Stream, and the correspon- ding zirconium dioxide coping were fabricated andtransferredtothemodelsituation(Figs.11–13). Veneering of the crown cap was performed using a suitable veneering porcelain (Figs. 14–16). For integration purposes, the CARES titanium abutment was screwed firmly into the implant. After try-in and adaptation of the peri-implant gingiva, the crown was definitively cemented using RelyX Unicem (3M ESPE; Figs. 17 & 18). _Conclusion The success of implant treatment does not de- pend on correct implant surgery alone. Prostheses too can contribute to avoiding peri-implantitis and to the long-term success of an implant by creating an optimal emergence profile. In this context, the individual abutment is to be regarded as the basis for successful implant prostheses. The intra-oral scan and consequent dispensing with plaster mod- els ensure that the digital prosthetic workflow is integrated right from the start (Fig. 19). This leads to significant simplification of the fabrication steps, with increased precision, and avoidssourcesoferror.Individualabutmentshapes can thus be designed and fabricated optimally via CAD/CAMtogetherwiththecorrespondingrestora- tion. In addition, this procedure enables reduced changing of screws and manipulation of the im- plant, which can lead to a reduction in peri-implant bone resorption.8, 9 Dental technicians and prosthodontists should be aware of the importance of an emergence profile at the time of temporary and definitive prostheses. It should therefore be the goal of any fixed implant restoration to come as close to these requirements as possible via customised recon- structions. Maintaining gingival dimensions and health is a decisive factor for the long-term success of im- plant reconstructions; after all, a healthy and func- tional peri-implant gingiva forms a barrier against the penetration of micro-organisms and bacteria. This enables long-term preservation of the peri- implant bone (not considering bone resorption induced by malfunction or overloading)._ Editorial note: A complete list of references is available fromthepublisher.
