7.1 Posterior Composite Restorations
In 2005, 166 million dental restorations were placed in the United States [
1
] and
clinical studies suggest that more than half were replacements for failed restorations
[
2
]. Replacement of failed restorations consumes 60% of the average dentist's
practice time (NIDCR 13-DE-102) and this emphasis on replacement therapy is
expected to increase as concerns about mercury release from dental amalgam force
dentists to select alternative materials. Resin composite is the most commonly used
alternative [
3
], but moderate-to-large composite restorations have higher failure
rates, more recurrent caries, and increased frequency of replacement as compared to
amalgam [
2
-
8
].
Results from clinical studies suggest that, after 8 years, the failure rate for
posterior composite restorations was at least 50% greater than that for high copper
