title: Photoelastic analysis of post core restorations.
abstract: Photoelastic models were used to analyse the effects of stress distribution around post-core systems. Parallel post designs were found to distribute stress more evenly to the tooth root, as compared to tapered posts. Screwed posts were found to be more undersirable.
