USER REPORT
A non-smoker and -diabetic 74-year-old
female patient presented with a severe
grade of multiple sclerosis and rheumatoid
arthritis. The patient was cared for in her
wheelchair. Over the last 30 years, she lost a
great part of her lower dentition, except the
third molar. The upper jaw consisted of an
old bridge and a removable overdenture.

The project, taking into account the critical
economic condition of the patient, was to
extract the root 43 and insert four mini
implants in the lower jaw, in accordance with
digital planning based on her cone-beam
computed tomography (CBCT) scan.
CONCLUSION
The Anthogyr Mini Implants System was
optimised for rehabilitating this patient with
disability problems in a simple and effective
way.
It is an affordable, less invasive, user-friendly
solution for all patients who are unable
to receive rehabilitations supported by
conventional implants, for anatomical or
economic reasons, or poor general health
conditions. The main indication is elderly
and special patients who need to anchor
their removable prostheses and have
sufficient residual bone crest to receive a
minimum implant size of 10mm in length and
Ø2.6mm in width.
Anthogyr Mini Implant System offers new
treatment possibilities for edentulous
patients as it is much more solid and reliable
than the old and conventional mini implants
which have been used so far. The Optiloc
retentive connection is also very compact
and performant.
The surgical protocol for these implants is
easy and less invasive: in most patients, the
procedure involves a flapless surgery, with
short surgical times and with no or very
little post-operative discomfort.
With regards to the Optiloc prosthetic
system, it is worth noting that a good
impression was made despite not having
a long follow-up. The Optiloc retentive
attachment performed much better

than conventional ball attachment and it
required a minimum amount of space in the
prosthesis when compared to these systems.
Hence, the Anthogyr Mini Implant System
has been adopted as a key alternative
treatment solution within the treatment
panel for all patients who need to support
a removable denture and who cannot
receive “conventional” implants. Overall, this
system is easy to use, fast, with excellent
retentive connection, and in many cases
also convenient, because it allows the
maintenance of the patient’s prosthesis
with small and easy adaptations. DA

for definitive denture relining and installation,
mounting collars were placed on each Optiloc
connection to protect the implant neck from
any resin or adhesive residue. Matrix housings
including retention inserts were then placed to
exert a slight compression between the mounting
collar and the matrix housing
