STAINLESS STEEL CROWNS FOR
PRIMARY MOLARS
Pre-formed or stainless steel crowns were
introduced to pediatric dentistry by Humphrey in
1950. Since then they have become an
invaluable restorative material in the treatment
of badly broken-down primary teeth. They are
durable, inexpensive, and easily and quickly
placed. The crowns are manufactured in
different sizes as a metal shell with some pre-
formed anatomy and are trimmed and contoured
as
necessary
to
fit
individual
teeth.

There are two commonly used types of stainless
steel crowns:
1.
Pre-trimmed crowns. These crowns have
straight, noncontoured sides but are
festooned to follow a line parallel to the
gingival crest. They still require
contouring and some trimming.
2.
Precontoured
crowns
(Ni-Chro
Ion
Crowns and Unitek Stainless Steel
Crown, 3M Co, St. Paul, MN). These
crowns are festooned and are also
precontoured. Some trimming and
contouring may be necessary but usually
are minimal. If trimming of these
crowns
becomes
necessary,
the
preontour is lost and the crown fits more
loosely than before trimming.
INDICATIONS FOR USE OF STAINLESS
STEEL CROWNS
1.
A restoration for a primary or young
permanent tooth with extensive carious
lesions.
2.
A restoration for a hypoplastic primary or
permanent tooth that cannot adequately
restored with silver amalgam or a
composite resin interior restoration
3.
A restoration for a tooth with a hereditary
anomaly,
such
as
dentinogenesis
imperfect or amelogenesis imperfect
4.
A restoration after a pulp therapy in a
primary or permanent tooth
5.
Restorations in disabled persons or others
in whom oral hygiene is extremely poor
and failure of other materials is likely
6.
As an abutment for space maintainers of
prosthetic appliances.

INDICATIONS
1.
Incisors with large interproximal lesions
2.
Incisors that have undergone pulp therapy
3.
Incisors that have been fractured and
have lost and appreciable amount of
tooth structure
4.
Incisors with multiple hypoplastic defects
or developmental disturbances (e.g.,
ectodermal dysplasia)
5.
Discolored incisors that are esthetically
unpeasing
6.
Incisors with small interproximal lesions
that also have large areas of cervical
decalcification
It is a challenging task to repair expensively
destroyed anterior teeth with restorations
that are durable, retentive, and esthetic.
There are several methods of providing full
coronal coverage to primary incisors; acid-
etched resin crowns, stainless steel crowns,
and veneered or open-face stainless steel
crowns.

the acid-etched resin crowns, the stainless steel crowns, and the open-face stainless steel crowns.
The most esthetic, and frequently placed crown,
is the acid-etched resin crown. Open-face
crowns are popular with many operators because
their retetion is superior to resin crowns;
however, esthetic results are compromised.
Plain stainless steel crowns provide a durable
restoration but esthetically unpleasing to most
parents. Stainless steel crowns with resin veneer
prebonded to the facial surface are commercially
available. These crowns provide a one-step
esthetic restoration that, unlike resin or open-
face crowns, can be placed in the presence of
- 195 -
hemorrahage without affecting the final
esthetics.
