Method 18 patients with trumpet shaped root canal entry, thin root canal wall or minor root crack were firstly repaired with Super Bond C&B material, then routinely restored with post and core technique. Following examination were made from three months to 1 5 years to observe the treatment effect. Result All these cases had good fixing effect except that one post became loose after one year′s observation. During the observing period, no fracture appeared in the roots and Super Bond C&B material, and no obvious changes were found in the alveolar bone condition. Conclusion For the roots that had bad shape and structure, good restoration effect could be achieved by using some proper material to repair the canal first and then restored with post crown.
