case report _ dental implantology I The gingiva adapted well to the contour of the restoration and sufficient occlusion was achieved. The temporary restoration was fixed with light- curing composite and the exact position was reconfirmed (Figs. 61 & 62). As planned, the fol- lowing day, the PMMA restoration was exchanged for the temporary bridge with the metal sub- structure. Function, aesthetics, and adhesive fix- ation were all checked, and the patient and the surgical team were all pleased with the results (Figs. 63–65). _Conclusion The application of computer technology and advanced 3-D imaging in implant dentistry using multiple interactive software applications makes it possible to create advanced designs that are multilayered, simultaneous and precise, enabling true resource optimisation. In the clinical case example, the design and production of a complex treatment plan were carried out using a state-of- the-art digital workflow. The data export proce- dure allowed for simulation of optimal abutment positioning. The CBCT image data was used to positiontheimplantsaccuratelywithinthedesired envelope of the diagnostic wax-up, allowing for the restorative data to be exported for CAD and fabrication of the temporary restoration before the treatment on the patient had even begun. The analogue or manual working steps in the labo- ratory were replaced by the digital workflow as made possible through advanced computer-aided processes. Resource optimisation using digital workflow has great advantages for both patients and dental implant treatment teams. When it is possible to deliver an immediate-load restoration supported by sufficient dental implants, our patients can continue their lives with less psychological bur- den, and implant teams benefit from predictable operating procedures and efficiency. The crafts- manship of a competent dental technical special- ist and the skill of a good dental surgeon when combined with 3-D preoperative planning can reduce operator and patient stress to a minimum, reduce patient morbidity and reduce surgical time, even when the operation must be relati- vely invasive, as represented by the clinical case illustrated._ Fig. 64_The situation before the insertion of the final piece of work six months after surgery.
