ABSTRACT:
A restoration for restoring a lesion in a tooth and method for making the same. The restoration comprises a layer of glass ionomer cement bonded to the lesion and a layer of amalgam disposed on the layer of glass ionomer cement. The restoration is formed by the process of applying a layer of wet glass ionomer cement on the lesion, placing a wet dental amalgam directly on the wet glass ionomer cement, and allowing the wet glass ionomer cement and the wet amalgam to harden to bond the amalgam to the tooth. Various modifications to the glass ionomer cement are disclosed to either improve the bond of the restoration's amalgam to the tooth or to enhance the cement's use in various dental procedures. Also disclosed are various dental procedures using the restoration and method of making the restoration which results in the resolution of certain shortcomings of current like procedures.
