From a cost-saving perspective for laboratories, the delivery of all metal frameworks of the NobelProcera system highly polished and readyto-use adds to the true benefits of centralised manufacturing. The five-year warranty on all products cannot be met by conventional fabrication techniques. The warranty ensures that if complications occur during clinical function, a new product can be ordered free of charge. Here, the uniqueness of virtual planning comes into play again, as all data is always available even after years and merely requires the click of a button to reorder. _Benefits of a versatile CAD/CAM system CAD/CAM technology has significantly revolutionised dental laboratory techniques and protocols. Advantages related to material and manufacturing processes will promote the continuous adoption of CAD/CAM systems over conventional casting techniques, as the technology offers several benefits compared to conventional framework fabrication. This development provides true benefits for the dental laboratory, the practitioner and, above all, the patient. From a laboratory perspective, the benefits of the technology and the new NobelProcera system are obvious. Cost-efficient and time-saving workflow with only one CAD/CAM system in the dental laboratory, high-quality products with unrivalled precision and free-virtual design options, and centralised production. The greatest advantage of the NobelProcera system is its clinical versatility. Not only the clinical situation, but also patients’ expectations and means can be met. The base components such as copings, frameworks and bars always guarantee maximum precision, material homogeneity and stability for all patients. This is true whether a low-cost, non-precious alloy substructure is veneered with resin or ceramic material or a high-end all-ceramic solution is requested, whether a conventional denture set-up is retained by an overdenture bar or an implant-retained removable restoration is finished with custom allceramic teeth and individualised gingiva-coloured composite._ Figs. 7a–d_Screw-retained restorations on dental implants (Nobel Active Implant, Nobel Biocare) simplify the clinical protocol by eliminating the need for correct alignment of multiple single abutments, in the case of a cement-retained bridge, allowing for easy removal if required (NobelProcera Implant Bridge Zirconia). The availability of NobelProcera restoration for use with numerous implant systems and platforms increases the laboratory and clinical efficiency of the system. The application of zirconia frameworks allows for easy closure of screw access channels with conventional composite resin. _contact cosmetic dentistry Hans Geiselhöringer Dental Technician Dental X Hans Geiselhöringer GmbH & Co.
