Beschreibung
Zusammenfassung:	A composite dental cement composition that is suitable for application with dental posts for either post insertion in a tooth or during core formation is provided, The cement composition includes a polymer matrix in an amount between about 15 and 50 weight percent, a filler in an amount between about 35 and 80 weight percent, and a lanthanide series compound in an amount between about 1 and 20 weight percent. The lanthanide series compound chemically interacts or pushes the air voids out between with the polymer matrix in order to increase compressive strength of the cement composition. Titanium powder may be added in order to increase compressive strength. A fluoride compound may further be added in order to substantially eliminate caries and further tooth decay.
