Porcelain laminate veneers for discolored teeth using complementary colors.Int J Prosthodont. 1993 May-Jun; 6(3):242-7.IJ
Porcelain laminate veneers are affected by the color of prepared abutment teeth, so that if these teeth are discolored they may cause problems in a restoration. This paper describes how complementary color theory is applied to resolve this situation and provide a more esthetic restoration. Tooth discoloration is classified into four base colors: orange, brown, blue-purple, and reddish gray, and a shade selection technique and a veneer fabrication technique are presented.
