Stainless steel crowns are semi-permanent restorations used for primary and young permanent teeth. They were introduced in 1950 as chrome-steel crowns. The objectives are to provide a biologically compatible and masticatorily functional restoration that maintains the tooth's form, function, and vitality when possible. There are three types - untrimmed, pretrimmed, and precontoured. Placement involves tooth preparation with reduction, selection of appropriately sized crowns, trial fitting, contouring and crimping, and final cementation.

1. Stainless steel crown is a semi permanent restoration used
in primary and young permanent teeth.
It was introduced as chrome-steel crown by ‘Humphrey’ in
1950.
OBJECTIVE
To achieve biologically compatible , competent for
mastication and clinically acceptable restoration.
To maintain the form and function and where possible the
vitality of the tooth should be maintained.

2. DIFFERENT TYPES OF STAINLESS STEEL CROWN
UNTRIMMED : Neither
trimmed nor contoured
PRETRIMMED : Crowns have
straight non-contoured sides.
PRECONTOURED:
Crowns are festooned

3. Steps Of Tooth Preparation In Stainless Steel
Crown
The mesio-distal
width of the tooth
is measured
before tooth
preparation
Step 1 : Rubber dam application
Reduce the
occlusion by about
1.0 to 1.5 mm
uniformly
Use diamond bur to
reduce the proximal
area, ledge formation is
avoided
Step 2 : Occlusal Reduction
Step 3 : Proximal Reduction
Step 4 : Final Preparation

4. Step 5 : Selection of crown for
trial fit
Crown size ranging
from 2-7 are available
and they can be tried
Step 6 : Crown
Placement
Step 7 : Clinical trial placement
Observe for blanching Festooning Trimming
Step 8
Contouring Crimping
Step 9 : Final Trial
Crown Adaptation
and Cementation
Step 9 : Finishing and
Polishing
Cementation
