Abstract: Establishing a harmonious relationship between the fixed restoration-tooth-periodontium (RTP) at the interface is crucial for achieving successful and long-lasting outcomes in esthetic zone restorations. This paper focuses on this core issue by elucidating the ideal RTP interface relationship, detailing a biological-esthetic dual-axis diagnostic classification for esthetic zone restorations based on RTP interface situation, and discussing clinical decision-making and treatment plans guided by this classification. Furthermore, specific strategies for managing the restoration margins in the esthetic zone are explored, emphasizing approaches that minimize adverse impact and enhance periodontal soft tissue protection on RTP interface in different diagnostic categories.
