Four solutions to correct divergent implants

By Zirkonzahn

---

Creating restorations on divergent implants, especially in the case of circular ones, is one of the biggest challenges for a dental team. Listed below are some of the new Zirkonzahn implant components and innovative working techniques which make it possible to produce stable and aesthetic restorations for implants oriented towards the palate or the vestibular area of the teeth, even in cases of total edentulism.

K80 Angled Screw Channel (ASC) Titanium Bases

The new K80 Angled Screw Channel (ASC) titanium bases combine two advantages in one product. On the one hand, they can be individually shortened to fit the patient's teeth; on the other hand, the angled screw channel allows to compensate for non-optimal implant positions, shifting the angulation from 0° to 30°. (fig 1)

Individual Raw-Abutments® in titanium

Raw-Abutments® (fig 2) are high-quality medical titanium blanks designed to produce individual abutments.

The industrially prefabricated implant connection guarantees maximum precision of adaptation, while the possibility of freely modeling the abutment allows to compensate for the divergences of the implants, correcting their orientation.

Double Screw Metal: stable and aesthetic circulars on buccally oriented implants.

The Double Screw Metal technique consists in integrating additional screw channels into the design of the bar: in this way, the titanium bar is screwed directly to the implants and the superstructure is screwed to the bar. With this innovative technique it is possible to avoid unsightly buccal canals and to create restorations on highly stable implants even in particularly complex cases without compromising the final aesthetics.

Bartplatte: circular on implants oriented towards the palate

Starting from the wax-up of the restoration, the bar can be geometrically adapted to the anatomy of the superstructure using the free modeling tools of the Zirkonzahn CAD software. In this way, it is possible to correct the orientation of the implants towards the palate and to create stable and aesthetic circulars even in the case of edentulous arches.
