The retreatment of failed root fillings in teeth with post retained crowns is preferable to their immediate apicectomy. This is because an apicectomy shortens the remaining root leaving less for retention of a subsequent post crown. The procedure also leads to irritants being sealed into the canal which may subsequently leak out past the retrograde restoration or through a lateral canal. If the root canal can be renegotiated, cleaned and obturated these problems are minimized.
The removal of the post should not be attempted, however, if it is felt that the force required to remove it could result in root fracture.
