Evaluating the longevity of restorative materials that seal the root canals of overdenture abutments.
Researchers have not established which restorative materials are most appropriate to seal the root canals of overdenture abutments. The author evaluated the longevity of a spherical amalgam, a composite resin and a glass ionomer in 123 patients. Results of this study showed a significant difference between the glass ionomer and the other two materials with regard to the time from placement to replacement of the restorations.
