Tensile bond strengths of five luting agents to two CAD-CAM restorative materials and enamel.

Statement Of Problem: CAD-CAM restorative materials are popular because they have high esthetic value and short fabrication time. Unfortunately these materials are brittle and tend to fracture under heavy occlusal load.

Purpose: The purpose of this in vitro study was to investigate the tensile bond strengths of 5 luting agents to 2 CAD-CAM restorative materials and enamel.

4-META use in dentistry: a literature review.

4-META (4-methacryloyloxyethy trimellitate anhydride) was invented and patented in Japan in January 1979 and patented in the United States in April 1979. For the first 8 years, 4-META dental products (manufactured by Sun Medical Co, Kyoto, Japan) were not readily available in North America. Most of the early research therefore was done in Japan and reported in Japanese.
