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.

Stainless steel crowns (PEDODONTICS)
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
