The angulated abutment

From the moment the prosthetics axis is different from the implant axis, it is necessary to rectify angles. ATOLL system's originality resides in the possibility to rectify angles of 12°, 20°, 30°, 40° and 360° rotation to have the locking hole permanently centered to the cingulate.

We can therefore correct abutments axis in 2 plans of the space according to the chosen prosthetics axis (See picture).


This operation takes place at the prosthetics laboratory on the model.
- For the single tooth: possibility to adapt the implant axis with that of natural teeth (see picture)


- For plural reconstructions: Parallelism of prosthesis insertion axis. (See picture)

Consequently, when implant axis are divergent, the abutments can be mobilized in 2 plans of the space:
- On the vertical plane, angulations are 12°,20°, 30°, 40°
- On the horizontal plane, they can be mobilized on 360°

How to act on the expansion rod owing to a stump/tenon axis modification.
In these cases, expansion rod is no longer straight, it is segmented in 2 plots interact with each other.


Both positions: circular (360°) and angular (12°, 20°, 30°, 40°) enable a wide range of solutions which allow to find a common insertion axis for all the abutments. Then we get a perfect parallelism for a precise placement of the structures.
