Restoration of endodontically treated teeth with carbon fiber posts - A prospective study

Abstract

A prospective study was started in 1995 to evaluate the success of carbon fibre reinforced epoxy resin (Composipost (RTD, St Egreve, France) posts used to restore endodontically treated teeth. All the teeth in the study had lost more than 50% of their coronal structure.

Methods

Fifty-nine carbon fibre Composiposts cemented with C & B Metabond and built up with Core Paste cores were placed into the teeth of 47 patients. Each tooth received a full-coverage restoration (porcelain fused to metal crown) and was followed for 6.7-45.4 months (average = 28.0 months, standard deviation = 10.7).

Results

Results for 52 teeth in 42 patients were analyzed. There were no fractures. The overall failure rate was 7.7% and the cumulative survival rate was 89.6% at the end of the follow-up period. The only statistically significant finding (p=0.04) was that posts in lower premolars were at higher risk of failure.

Conclusion

Composipost posts are among the most predictable systems available today. Composipost posts in the upper anterior teeth are associated with a higher success rate and longer life than those placed in premolars, especially lower premolars.

This study contributes to the growing body of evidence that supports the use of Composipost posts in the restoration of endodontically treated teeth.
