    摘要： A process is provided for tabletting spherical dental amalgam alloy. The process comprises treating the particles of spherical alloy by contacting them with a hydrochloric acid solution of cupric chloride, separating the acidic cupric chloride solution from the spherical alloy particles, washing the spherical alloy particles with water, drying the spherical alloy particles to remove residual water and then compacting the treated spherical alloy particles into a solid form such as a tablet.

    摘要： A multi-component composition suitable for amalgamation with mercury to form a dental amalgam, an amalgam and a method for producing such a multi-component composition. The multi-component composition has: from 30 to 90% (by weight) of a first component containing at least 30% silver, at least 20% tin and at least 10% copper; from 10 to 70% (by weight) of a second component, or alternatively, from 5 to 65% (by weight) of a second component and from 5 to 65% (by weight) of a fourth component, the second and fourth components containing at least 30% silver, at least 20% tin and at least 10% copper; and up to 15% (by weight) of a third component containing silver and/or alloy powder containing at least 80% (by weight) silver. The first component is spherically shaped atomized alloy powder. The second component is mechanically worked atomized alloy powder. The surface area to volume ratio of the powder of the second component is greater than the surface area to volume ratio of the powder of the first component. The fourth component is irregularly shaped as atomized alloy powder.

    摘要： Wet glass ionomer cement is applied to a tooth lesion. Before the cement hardens, wet amalgam is applied on top of the glass ionomer cement. The glass ionomer bonds to the tooth, and the interface of the wet cement and wet amalgam allows strong ionic bonds to form between the glass ionomer cement and the amalgam, to provide an exceptionally strong bond between the amalgam and the tooth.
