Within the direct concept, the distal implants can be deliberately positioned at an angle in order to take full advantage of the local bone in cases of reduced bone availability and to avoid perhaps a complex augmentation. Angulation of the abutments of up to 30° permits to achieve a uniform insertion direction. The impression coping has been designed as a universal abutment and can, for example, be polymerized directly into the existing prosthesis as interim restoration. For extensive restorations, crown bases for casting with precious metal alloys (PA) or non-precious alloys (NPA) are available.
