Obtaining optimal esthetics with veneered zirconia and lithium disilicate frameworks on substrates of different colors

Objective This study sought to describe the clinical and laboratory procedures and to discuss aspects involved in obtaining satisfactory esthetics on substrates presenting different colors. Clinical considerations This case report describes the clinical and laboratory procedures for obtaining an optimal esthetic result using different ceramic framework materials veneered with feldspathic ceramic over substrates of different colors. Zirconia frameworks were used for darkened substrates and were reinforced with lithium disilicate for substrates with minimal discoloration. The same feldspathic veneering ceramic was applied to provide similar translucency and color for favorable esthetics. Conclusions The materials explored in the present case report presented favorable aesthetic results in masking darkened substrates. Clinical significance Clinicians should consider the condition and color of the substrate when selecting the restorative material for masking such a condition.
