| Abstract: |
| ［Objective］ To investigate the clinical effect of three methods to get casting post-cores. ［Methods］ Total of 261 residualroots and crowns, after the perfect root canal therapy were restored by three different methods, All patients were followed up 0.5-4 years. ［Results］Two hundred and sixty-one post-cores had effective border position and retention, No periondontal diseases and secondary caries arose. There were no significant difference in short-term results between three groups (P>0.05). ［Conclusion］ It is feasible to get casting post-cores by the three methods, but the attention must be paid to the selection of endications seriously. |
