Endodontically treated teeth may require reinforcement.
Posts retain the core build-up which is needed due to extensive loss of coronal tooth structure.
Remaining dentinal structure will dictate if a post is indicated to compensate for extensive loss of coronal tooth structure.
Aim to preserve as much coronal and radicular tooth structure as possible.
Use a ferrule when using a post. An adequate ferrule is minimum 2 mm vertical height and 1 mm of dentin thickness.
If an all-ceramic crown is chosen as the final restoration anteriorly, the colour and opacity of the post may lead to discolouration and shadowing of the crown, especially for an IPS e.max® restoration. Thus, opaquer would be critical if metal weas used for strength.
