ABSTRACT. Most endodontically treated teeth require restoration with a post and core system. The present trend is to replace metallic posts by nonmetallic passive systems such as carbon fiber based ones. They were developed more than 10 years ago, but they have not been currently applied ever since. The Absolu (Spad-France) carbon fiber post and core system and the Dentatus (Svenska Dentorama AB) metallic post system were subjected to axial and angled compression loads. Two sets of monoradicular teeth were used: one of them were teeth restored with Dentatus and Polofil. The behavior of the Absolu system restoration displayed a slightly inferior resistance to fracture as compared to that of Dentatus restorations. The behavior was also influenced by the luting agent. The test values show that the former system resists well to normal occlusal loadings. The deformations occurring in the Dentatus restorations are not present in the Absolu restorations since the latter system is more rigid. The Absolu system made by bonding restorative materials to tooth structures result in monobloc restorations. The fracture of the post does not lead to root damage and therefore the root can be restored again, after removing the post by burs and solvents.
