Radiograph revealed satisfactory root filling in the apical third. Deep bite was observed for the patient.

Two treatment plan were considered, Separate post and core followed by the full crown or Richmonds crown, which has the crown and post in a single component. Since retention of crown was foreseen as the main problem as the patient had small clinical crown and deep bite, it was decided to proceed with Richmonds crown.

Post cementation radiograph reveals satisfactory adaptation of the post crown with excellent marginal adaptation. The only disadvantage of this crown is that, if retreatment is required because of failing root canal, then it is possible by surgical intervention only.
