Cumulative costs for the prosthetic reconstructions and maintenance in young adult patients with birth defects affecting the formation of teeth.
[dentinogenesis imperfecta]
To
assess
retrospectively
the
cumulative
costs
for
the
long
-term
oral
rehabilitation
of
patients
with
birth
defects
affecting
the
development
of
teeth
.
Patients
with
birth
defects
who
had
received
fixed
reconstructions
on
teeth
and
/
or
implants
>
or
=
5
years
ago
were
asked
to
participate
in
a
comprehensive
clinical
,
radiographic
and
economic
evaluation
.
From
the
45
patients
included
,
18
were
cases
with
a
cleft
lip
and
palate
,
five
had
amelogenesis
/
dentinogenesis
imperfecta
and
22
were
cases
with
hypodontia
/
oligodontia
.
The
initial
costs
for
the
first
oral
rehabilitation
(
before
the
age
of
20
)
had
been
covered
by
the
Swiss
Insurance
for
Disability
.
The
costs
for
the
initial
rehabilitation
of
the
45
cases
amounted
to
407
,
584
CHF
(
39
%
for
laboratory
fees
)
.
Linear
regression
analyses
for
the
initial
treatment
costs
per
replaced
tooth
revealed
the
formula
731
CHF
+
(
811
CHF
x
units
)
on
teeth
and
3369
CHF
+
(
1183
CHF
x
units
)
for
reconstructions
on
implants
(
P
<
.
001
)
.
Fifty
-
eight
percent
of
the
patients
with
tooth-supported
reconstructions
remained
free
from
failures
/
complications
(
median
observation
15
.
7
years
)
.
Forty
-
seven
percent
of
the
patients
with
implant-supported
reconstructions
remained
free
from
failures
/
complications
(
median
observation
8
years
)
.
The
long
-term
cumulative
treatment
costs
for
implant
cases
,
however
,
were
not
statistically
significantly
different
compared
with
cases
reconstructed
with
tooth-supported
fixed
reconstructions
.
Twenty
-
seven
percent
of
the
initial
treatment
costs
were
needed
to
cover
supportive
periodontal
therapy
as
well
as
the
treatment
of
technical
/
biological
complications
and
failures
.
Insurance
companies
should
accept
to
cover
implant-supported
reconstructions
because
there
is
no
need
to
prepare
healthy
teeth
,
fewer
tooth
units
need
to
be
replaced
and
the
cumulative
long
-term
costs
seem
to
be
similar
compared
with
cases
restored
on
teeth
.
