Which method is often recommended to improve the retention of indirect restorations?

The method involving the use of strong luting agents is recommended to improve the retention of indirect restorations because these agents can create a more secure bond between the restoration and the tooth structure. Strong luting agents are formulated to have optimal adhesive properties that enhance the mechanical and chemical bonding, which is crucial for the long-term stability of indirect restorations such as crowns, bridges, and inlays.

When these agents are properly applied, they fill imperfections between the restoration and the tooth surface, thereby enhancing retention through increased surface area contact and reducing the likelihood of debonding over time. In contrast, while factors such as the size of the posts, tooth reduction, and moisture control are important considerations in prosthetic dentistry, they do not directly contribute to the adhesive bond strength in the same way that the choice of luting agent does. This highlights the critical role of luting agents in ensuring successful and durable indirect restorations.
