<p>The present invention relates to a tooth filling material, particularly for temporary use, composed of two components, which have been combined and have reacted with each other. The material is characterized in that one component (A) is pulverulent and mainly comprises a first powder, which in its turn mainly comprises zinc oxide, and a second powder, which comprises a filler material, which is one or several ceramic materials, which are chemically stable in relation to phytic acid, that the second component (B) is in a liquid state and is composed of 35-55 % phytic acid, the rest being mainly water, that the material after a careful mixing of the two components with each other is hardened in 2-10 minutes, and that the compressive strength of the hardened material is 35-55 MPa.</p> |
