Uso da coroa de aço pré-formada em molares permanentes: uma revisão de literatura

Abstract

The aim of this study was to report under what conditions pre-formed stainless steel crowns (SSC) have been used in permanent molars, and their clinical performance. For the review, clinical studies on the subject, conducted in humans, in the form of original research and case reports, were selected. The bibliographic search was carried out in the MEDLINE (PubMed) and Virtual Health Library databases in October 2024. A total of 555 articles were retrieved from the database search. Six articles were included through the database search. Four articles were retrieved manually. Finally, ten articles published between 2003 and 2023 were included in the review. Six studies are cross-sectional, one is a pilot study, one is a case report, one is a cohort study, and one is a controlled clinical trial. The studies were based on samples from Colombia, the United States of America, France, Greece, Iran, England, Turkey, and South Korea. The studies used the conventional technique for preparation and cementation of stainless steel crowns, except for two studies that did not mention the technique. The clinical conditions in which CAI was used included molar incisor hypomineralization, caries, endodontically treated teeth, enamel hypoplasia, amelogenesis imperfecta, dentinogenesis imperfecta, replacement of previously placed steel crowns, and cusp fractures (usually due to intracoronal restorations). Follow-up time ranged from 15 days to 118 months. Stainless steel crowns showed high clinical success rates, ranging from 84.3% to 100%. They demonstrated good clinical performance and high durability in young permanent molars, constituting an effective restorative alternative in clinical practice.
