The Effect of IDS CAD White Plus Solution on the Delta E Value of Zirconia in Representative Restorative Applications
Abstract:
Zirconia is increasingly favored as a restorative material of choice for crowns because of its combination of strength and esthetic appearance. Matching the shade of the crown to the shade of the patients natural dentition is a key requirement for the success of full coverage restorations, including those made of zirconia, and is a frequent challenge faced clinically. In addition to their color properties, teeth have varying degrees of translucency, and in order to look natural, crowns must also incorporate a certain amount of translucency. However, this can permit the dark underlying abutment to show through and alter the tooth shade. IDSCAD White Plus (IDS CAD, Centreville, VA) solution has been developed as a solution for this problem as it relates to zirconia crowns. Knowledge of the effectiveness of IDS CAD WhitePlus solution could be used to improve the esthetic outcome of zirconia full coverage restorations for patients. The purpose of this study is to investigate the effect of IDS CAD's White Plus solution on the final shade of varying brands and thicknesses of zirconia. The application of the IDS CAD White Plus solution did function as intended to opaque the zirconia and reduce the Delta E value of the zirconia over both the ND8 and the Titanium stumpf. However, none of the Delta E values calculated were above the minimum Delta E required to be perceptible to the human eye (2.6 from our literature review), or the minimum Delta E found to be clinically unacceptable (3.7 from our literature review).
