  • Process and kit for producing a dental restoration piece
    Patent number: 7374422
    Abstract: A process is provided for producing a dental restoration piece that has a frame with first and second portions and a blended synthetic material covering a first portion of the frame, the heat expansion coefficient of the blended synthetic material being different than the heat expansion coefficient of the frame material. Prior to a thermal treatment of the dental restoration piece, at least the second portion of the frame is covered with a heat protection paste, whereby the heat protection paste limits the increase in temperature of the frame resulting from thermal treatment of the dental restorative piece to effect curing of the blended synthetic material to a lesser temperature value than if the heat protection paste had not been applied onto the dental restorative piece. Also disclosed is a kit for practicing the process.
