Abstract
Introduction: All ceramic restorations have become popular for their esthetics and durability. These restorations possess a unique biocompatibility, as well as favorable physical and mechanical properties. Debonding of ceramic restoration due to various clinical reasons may affect the shade of the restorations. Aim: This in vitro study aimed to evaluate the color change of three different all ceramic materials (Monolithic lithium disilicate material, hybrid ceramic material and monolithic translucent zirconium material) after debonding with an Erbium Chromium laser.
Material and Methods: Human first premolar tooth was selected for this study;Tooth was prepared,an epoxy resin dies were duplicated from the prepared tooth, optical impression for each die, crowns were designed and Ten e-max CAD (shade A1), ten Vita Enamic (shade 1M2) and ten InCoris TZI (shade A1) crowns were milled, All the crowns were bonded to their corresponding dies;. Crowns were debonded using Er, Cr: YSGG. Shade was measured before and after debonding for each group.
Results: There was a statistically  significant difference in the mean ΔE in the three tested subgroups (P= 0.008) after laser debonding data was collected, tabulated and statically analyzed.
Conclusion: (InCoris TZI) and (e-max CAD) crowns, can rebond and reuse after Erbium laser debonding, on the contrary of the (Vita Enamic) crowns without great change in shade.
