With the increasing demand for dental aesthetic outcomes, techniques for composite resin restoration intended for anterior teeth have been widely applied due to their minimally invasive and superior esthetic performance. Despite promising short-term outcomes, the long-term prognosis of anterior resin restorations remains challenging. Frequently reported complications include restoration fractures and decoloration. Material selection, operative procedures, and patient-related factors can affect the long-term outcomes of restorations. This review aims to systematically analyze the long-term clinical performance of resin restorations in anterior teeth. The key factors influencing treatment efficacy are also investigated. The findings are expected to provide a basis for optimizing clinical strategies in procedures for anterior composite resin restoration.
