Cast or fiber posts a summary of evidence from vitro studies.
METHODS
Medline, the Cochrane Controlled Trials Register, China National Knowledge Infrastructure and China Biology Medicine disc were searched.


METHODS
Only randomised studies were included.


METHODS
Data were independently extracted. Standardised mean differences were combined and analysed using meta-analysis.


RESULTS
Thirteen studies were included; premolars were used as specimens in six studies, central incisors in five studies and canines in three articles. There was considerable variation in both alloy and fibre materials used between studies. The standardised mean difference of the combined data was 0.64 (95% confidence interval, 0.08-1.20; P < .001), indicating that the cast post group displayed significantly higher fracture resistance than the fibre post group.


CONCLUSIONS
On the basis of the current best available evidence, we concluded that cast posts had higher fracture resistance than fibre posts.
