Post-endodontic restoration: posts, cores, crowns
Conservative Dentistry and Endodontics · Dental (BDS)
Study notes
A root-treated molar has lost most of its crown. Why is a post + core + crown planned, not just a filling? With minimal coronal tooth left, a filling has nothing to grip and the hollowed tooth fractures under chewing. The post anchors in the root canal for retention, the core rebuilds the missing structure, and the crown encircles everything — with a 2 mm ferrule of sound tooth gripping the crown's margin — distributing forces safely. Students learn the chain: retention (post) → build-up (core) → protection (crown).
