Metal cast post core and glass fiber-reinforced resin post core in the re-restoration for residual root of anterior tooth:clinical observations

AIM:To compare the clinical effect of glass fiber-reinforced resin post core and metal cast post core in the re-restoration for residual root of anterior tooth.METHODS:Fifty anterior residual roots which have failed in post-core crown restoration but could be restored were included in this clinical observation.Twenty-eight residual roots were with glass fiber-reinforced resin post cores,and the other 22 roots were with Ni-Cr alloy cast post cores.Subsequently,all teeth were restored with PFM crowns.RESULTS:At 24 months follow-up,the success rate of the metal cast post core group was 72.73%,with 2 roots fracture,4 post crowns falling-off.The success rate of the glass fiber-reinforced resin post core group was 96.43%,with only 1 core crown falling-off.The success rates between the two groups were statistically different.CONCLUSION:Glass fiber-reinforced resin post core shows better effect in the restoration for residual root of anterior tooth.
