The criterion for success of modern implants was defined at the Toronto Conference as “The resultant implant support does not preclude the placement of a planned functional and esthetic prosthesis that is satisfactory to both patient and dentist.” In other words, esthetics is a crucial requirement for success in implant treatment for both patients and dentists. However, esthetic standards vary with age, gender, era, region, sensibilities, and the like, and the esthetic success desired by patients does not necessarily match the esthetic success envisioned by dentists. Therefore, it is important for dentists to appropriately understand the esthetics desired by individual patients. In this review, we considered the index currently used for evaluating esthetics for a single tooth implant, and examined the criterion for success of esthetic implant treatment.
