Influence of Restorative Materials on Color of Implant-Supported Single Crowns in Esthetic Zone: A Spectrophotometric Evaluation

Figure 2

(a) demonstrates the effect of different restorative material combinations on the color of the implant crown. The gz group showed the smallest color change (: ), and the zz group showed the biggest (: ). (b) demonstrates the effect of different restorative material combinations on the color of the peri-implant mucosa. The zz group showed the smallest color change (: ), and the tz group showed the biggest (: ).
