Summary

A randomized parallel-group clinical pilot study was designed to evaluate the impact of glass fiber reinforced composite posts compared to prefabricated titanium posts on long term survival of adhesively restored endodontically treated abutment teeth.

Detailed description

Compared to vital teeth the complication rate of restorations fixed on endodontically treated abutment teeth is higher. Endodontically treated teeth are more prone to fracture due to the higher amount of calcified tooth structure loss. To level the biological short coming the choice of the mechanically appropriate post material is still a major concern. There a two major approaches. One is to use a rigid material to stiffen the post-endodontic complex and the other is to use a material which shows dentin-like material properties to allow the post-endodontic complex to flex under load. It was aim of the presented randomised controlled trial to compare the survival rates of abutment teeth self-adhesively restored with either prefabricated glass-fiber reinforced composite posts or titanium posts. The null-hypothesis was that there is no difference regarding survival rate between glass-fiber and titanium post restored endodontically treated abutment teeth with two or less remaining cavity walls.

Conditions

• Endodontically Treated Teeth
• Tooth Fractures

Type	Name	Description
DEVICE	prefabricated titanium post	posts: diameter of 1.4 mm; length of 13 mm adhesively luted within the root canal using self-adhesive resin cement and direct composite cores using an etch-and-rinse adhesive were built up crown preparation was performed, while the finishing line for the final restoration was set at least 2 mm apical the composite build-up in dentin to ensure a proper dentin ferrule design
