New technique for production of full-arch prosthetics on divergent anterior implants
The production of full-arch prosthetics on divergent anterior implants is one of the most challenging jobs for a techno-clinical team. However, with the new Double Screw Metal technique and the integration of a primary bar in the final restoration is now possible to strike a balance between function, stability and aesthetics.The design of the titanium bar incorporates an innovative CAD/CAM workflow, in which four additional screws are added to screw the superstructure to the bar.
These screws are generated with the new Double Screw Metal function of the Zirkonzahn.Modellier software (Attachment module), which allows the addition of virtual screws within the bar design. Besides, the 3D rendering provides the optimal position of the screw channel in the primary structure, as well as the ideal fit of the screw head in the superstructure. Thus, the titanium bar is double screwed – both to the implants and to the secondary structure.
The integration of the Double Screw Metal technique not only avoids unaesthetic vestibular channels in the anterior region, but also improves post-operative maintenance and hygiene. With the Double Screw Metal technique it is thus possible to produce highly stable, bar-supported rehabilitations even in complex cases without compromising the full arch aesthetics.
