The stainless-steel crown (SSC) is one of the most important procedures in pediatric restorative dentistry.
Stainless-steel crowns cover and protect the entire tooth and are very durable.
They also are very difficult to dislodge if placed properly, with excellent adaptation to the tooth.
They represent the preferred therapy for primary molar teeth after pulpotomy.
The stainless-steel crown is readily retained (often for the lifespan of the primary molar), because it fits over the contour of the buccal, lingual, mesial and distal surfaces of the tooth.
This "snap-on" feature of stanless-steel crowns. This is obviously distinctly different from the way in which precision laboratory-fabricated cast restorations are placed in permanent teeth, after parallel preparation of the tooth and avoidance of any undercuts during tooth preparation.

The pre-cut, pre-contoured and pre-crimped stainless-steel crown is intended to fit over the cervix of the crown preparation with the same "snap-on" effect as the older generation, non contoured crowns, but without all the trimming/reduction and contouring procedures.
Additional crimping can also be done on the pre-contoured crowns to further improve the mechanical retention.
It is desirable to avoid as many of the cutting and crimping steps as possible in order to save time during the procedure. This was the reason for the development of the pre-contoured crowns.
