Objective    To study the clinical effect of glass fiber post and resin core in combination with a zirconia-ceramic crown in the restoration of residual roots and crowns.     Methods    Forty-eight patients were enrolled in the study. A total of 65 teeth (26 anterior and 39 posterior with 22 abutment teeth; 18 residual roots and 47 residual crowns) were restored with glass fiber post and resin core in combination with a zirconia-ceramic crown. After 6 months to 2 years

all patients were examined and the restoration effect was evaluated.     Results    In all cases

3 post debondings occurred after the restoration of residual roots (failure rate 4.62%)

in which 2 cases were restored after re-treatment and 1 case was withdrawn. No fracture of zirconia-ceramic crown was observed. No root or post fracture was observed clinically or on radiographs. No apical or periodontal shadow was observed on radiographs

and no secondary dental caries of tooth neck was found.     Conclusion    The application of glass fiber post in combination with a zirconia-ceramic crown is feasible in metal-free restoration of residual roots and crowns.
