title: [Restoration of molar residual roots and crowns with multiple canals by unparalleled posts: an evaluation].
abstract: OBJECTIVE
  To repair the residual roots and crowns of the molars with multi-canals using unparalleled posts and cores and ceramic crowns.
  
  
  METHODS
  Unparalleled insertion of the posts and cores was adopted in the casting of the ceramic crown to repair the residual roots and crowns of the molars.
  
  
  CONCLUSIONS
  Unparalleled insertion of the posts increased the retention strength of the cores, which provided a solid foundation for the restoration of the molars with ceramic crowns, therefore yielding better clinical effect in repairing the molars.
