Cross-arch arrangement in complete denture prosthesis to manage an edentulous patient with oral submucous fibrosis and abnormal jaw relation.
[oral submucous fibrosis]
A
patient
with
oral
submucous
fibrosis
and
resorbed
ridges
poses
a
challenge
for
prosthodontic
rehabilitation
because
of
the
limited
mouth
opening
and
fibrotic
mucosa
.
The
fabrication
of
prosthesis
is
very
difficult
due
to
abnormal
jaw
relations
,
influencing
the
long
-term
prognosis
of
the
patient
.
To
present
a
case
of
oral
submucous
fibrosis
with
severely
resorbed
edentulous
ridges
which
was
successfully
managed
by
adopting
a
modified
technique
in
fabricating
a
complete
denture
prosthesis
.
A
55
-
year
-old
female
patient
with
completely
edentulous
maxillary
and
mandibular
arches
diagnosed
with
oral
submucous
fibrosis
was
rehabilitated
with
complete
dentures
by
recording
neutral
zone
for
resorbed
mandibular
ridge
and
by
arranging
the
posterior
teeth
in
cross
arch
relation
for
compensation
of
the
abnormal
jaw
relations
.
The
cross-arch
arrangement
of
posterior
teeth
provides
a
more
stable
and
retentive
complete
denture
prosthesis
for
patients
with
severely
resorbed
ridges
and
a
wider
mandibular
arch
.
