Single-implant restorations in the anterior maxilla have become a routine treatment option. While customized tooth-colored prosthetic components show greatly improved clinical outcomes, esthetic success relies not only on the restorative result, but also on the condition of the soft tissues. A common esthetic shortcoming is the grayish appearance of the peri-implant soft tissues, which are difficult to manipulate around dental implants. The parameters and clinical guidelines that should be used to influence esthetic success and avoid the gray zone around implant restorations can be categorized into five key factors: (1) optimal three-dimensional implant placement for functional and esthetic long-term implant success; (2) maximized soft tissue thickness to conceal the implant-restorative interface; (3) proper abutment selection to improve biocompatibility, tissue stability, color, translucency, and fluorescence; (4) careful crown restoration to imitate the natural teeth; and (5) awareness of the lip line, which may greatly influence the final outcome. Mimicking the inherent optical properties, especially fluorescence, of natural teeth with implant components and crown materials is fundamental for ideal restorative and soft tissue esthetics.
