Objective: to categorize and examine the existing methods and materials proposed to enhance the bonding of zirconia to dental substrates. Materials and Methods: A review of studies was conducted regarding the evaluation of zirconia bonding to dental substrates. On the basis of papers published between 2019 and 2023, the research was conducted in January 2024. Prisma, or the Preferred Reporting Items for Systematic Reviews and Meta-Analysis, was the basis for the methodologies used in this investigation. Results: After ageing, MDP cement in combination with tribochemical silica coating (TSC) or SA produced more durable results. Furthermore, when SA and TSC are treated with non-MDP cement and non-MDP primer, better bond endurance is seen. Compared to SA, TSC might improve bond durability; when mixed with SA or TSC, MDP cements might have comparable results. The zirconia-resin interface should priorities two important aspects when choosing bonding mechanisms: strong initial bond strength and long-term bond endurance. The effectiveness of treatment may be limited because mechanical tests, such as micro-tensile bond strength and shear bond strength, may not accurately reflect material behaviour under practical settings, even though they are frequently used to evaluate the bond quality between resin luting agents and zirconia substrates. Conventional cements can also be used to cement zirconia crowns if the right crown preparation strategy guarantees adequate retention without bonding. Conclusion: The pressures applied during chewing and the state of the tooth are two more elements that significantly affect the retention of restorations in addition to adhesion techniques. Adhesive methods are becoming increasingly important in order to guarantee the effectiveness of restorations, as minimally invasive techniques become more popular.
