USER REPORT
were verified in the mouth and then the
ceramic crown was sealed outside of the
mouth on the abutment with Fuji plus
cement (Figs. 10-13b). This allowed for
perfect control of excess cement and to
guard against any risk of “cementitis”.
The abutment and crown system was
impacted with the Safe Lock system,
mounted on the chair unit. The Safe
Lock system made it possible to secure
the impaction. The recommended five
impacts were applied and the prosthetic
restorations set permanently (Figs. 10 to
13b). The good aesthetic result is related
to the symmetry of the emergence
profiles; the narrow diameter of the
implant was perfectly adapted to this
clinical situation.

CLINICAL CASE 2: LIMITED
MESIODISTAL SPACE AND CLOSENESS
OF THE APICES OF THE ADJACENT
TEETH
A 20-year-old man presented a unilateral
agenesis at 12. This patient had just
finished his orthodontic treatment.
His brackets had been removed a few
months before. He presented with a
removable partial denture while waiting
for the placement of an implant. The
retroalveolar x-ray exams and CT scan
cross sections showed an extremely small
mesiodistal space, especially at the level
of the apices of the adjacent teeth (Figs.
14–16).
The treatment of this small space required
increased precision during the surgical
phase. The insertion axis was visualised
on the 3D reconstruction of the CT scan
cross sections using Simplant software;
peroperative retroalveolar x-rays were
carried out at each drilling sequence.
The treatment of this very small
mesiodistal space was only made possible
by the use of an implant, 2.8mm in
diameter (Axiom 2.8 by Anthogyr), without
which it would have been necessary to
resume orthodontic treatment in order
to align the apices of the adjacent teeth,
which this young patient did not want
(Figs. 17-18).
