  • Composite dental cement composition containing titanium
    Patent number: 5034433
    Abstract: 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 titanium in an amount between about 1 and 15 weight percent. The titanium ingredient chemically interacts with the polymer matrix in order to increase compressive strength of the cement composition.
