checked (Figs. 19 & 20). These magnifying devices, such
as microscopes, allow for a better identification of the areas
to be eliminated, and to distinguish those only to be
polished, as metal abrasions must be eliminated (Fig. 21).
As soon as all these points are correctly managed, the result
will be a good fitting of the superstructure with a smooth

friction, with the location of the attachments perfectly in the
centre of the housings (Fig. 22). Only at this point were the
black lab caps inserted, and the superstructure was inserted
on the bar after being sprayed with marking spray; this
allows you to check how the attachments act during the
insertion (Fig. 23). Once the superstructure was extracted,

excluding the attachments in order
to avoid any interference so that the
correct interface can be searched.

superstructure all the retentive laboratory caps were
placed, the bar and attachments sprayed anew with
the marking spray and the correct sitting is checked.

Figs. 24 & 25: After removing the superstructure, the retentive areas of the attachments
are searched with the microscope; the wrong areas of contact on the attachments
show how they do not work properly. This because there are some points on the
structure that have to be discarded as they will interfere with the bar insertion.
Fig. 26: After correcting of those points that
interfere with the proper function of the
attachments, the superstructure sits correctly
over the bar and this is showed by the
correct contact areas on the attachments.
