Cast or fiber posts a summary of evidence from vitro studies
1University of British Columbia, Vancouver, Canada.
Data Sources:
Medline, the Cochrane Controlled Trials Register, China National Knowledge Infrastructure and China Biology Medicine disc were searched.
Study Selection:
Only randomised studies were included.
Data Extraction And Synthesis:
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.
