1. INTRODUCTION
Edentulous
pa-ents
o.en
experience
problems
with
their
mandibular
complete
dentures.
Lack
of
stability
and
reten-on
of
their
mandibular
denture,
together
with
a
decreased
chewing
ability
are
the
main
complaints
of
these
pa-ents.
A
current
treatment
possibility
is
the
placement
of
2
ERA
mini-‐implants
in
the
mandible
to
support
an
provisional
overdenture
to
avoid
early
loading
of
the
defini-ve
implants.
TECHNICAL
DETAILS
•Type
of
implants:
ERA
implant
3.75
x
11mm
(3)
and
ERA
implants
2.2
x
11
mm
(2)
•Type
of
ERA
abutment:
ERA
Implant
Abutment
only,
0°,2mm
cuff
•Occlusion
design
for
the
complete
denture:
•Lingualized
•Type
of
resin
for
overdenture:
•
Maxilar:
Duratone
•Mandibular:
Duratone
CONCLUSIONS
The
use
of
mini
implants
in
the
interforaminal
region
with
immediate
load
will
preserve
intact
the
defini-ve
implants
in
the
period
of
osseointegra-on.
The
use
of
implants
in
the
mandibule
maintain
the
bone
level,
reducing
or
even
stopping
the
degree
of
alveolar
atrophy.
The
only
disadvantage
of
the
implant-‐supported
prosthesis
is
cost.

CASE
DETAILS
A
48
year
old
female
pa-ent
presents
because
the
severe
resorp-on
of
the
mandibular
residual
ridge,
clasificated
as
a
C-‐w,
according
to
Misch.
The
final
treatment
plan
was
to
place
3
ERA
dental
implants
of
3.75
x
11mm
and
2
ERA
mini-‐implants
of
2.2
x
11mm.
During
the
surgical
phase
the
2
ERA
mini-‐implants
where
immediatly
loaded
to
support
an
overdenture,
while
wai-ng
for
the
three
months
of
osseointegra-on
of
the
3
ERA
implants
of
3.75x11mm.
By
implemen-ng
this
protocol,
an
op-mal
defini-ve
result
could
be
achieved,
together
with
immediate
pa-ent
sa-sfac-on.
However,
coopera-on
among
several
disciplines
and
careful
pa-ent
selec-on
were
required.
A.er
wai-ng
the
three
months
of
osseointegra-on
of
the
3
ERA
implants
3.75x11mm,
the
overdenture
was
retrofiked
to
the
abutments.
INTERDISCIPLINARY
APPROACH
An
interdisciplinary
approach
is
necessary
to
evaluate,
diagnose,
and
resolve
aesthe-c
problems
using
a
combina-on
of
implant,
periodontal,
and
prosthodon-c
treatments.
When
pa-ent
treatment
requires
a
comprehensive
approach,
communica-on
among
the
disciplines
is
cri-cal
in
achieving
improved
aesthe-c
outcomes.
