Abstract

BACKGROUND

Preformed metal crowns, also known as stainless steel crowns (SSC), are utilized for providing full coverage to young permanent teeth and have been used extensively as restorations of primary teeth for approximately 65 years.

AIM

Evaluate permanent tooth SSC longevity as an interim restoration for teeth requiring full coverage restoration in pediatric patients.

DESIGN

Retrospective chart review from 2006 through 2014 in a hospital-based dental clinic for permanent tooth pre-fabricated crown longevity. One hundred and fifty-five SSCs were evaluated with regard to: age of patient at restoration placement, diagnoses, and duration of crown service. Duration service was further categorized as successful or failed.

RESULTS

Of 155 SSCs, 137 were considered successfully functioning. Total failures were 18. The overall combined success rate for the study group was observed to be 88% with an average service period of 45.18 months. Significant success was noted in patients less than 9 years of age, and significant failure was observed in patients 12 years and older.

CONCLUSIONS

Stainless steel crowns are a viable option for interim restoration needs, with an 88% overall success rate during an average service period of 45.18 months.
