What leads to increased strength in interim restorative work?

In interim restorative work, increased strength is often associated with the increased size of connectors. Connectors play a crucial role in distributing forces and enhancing the mechanical stability of the restoration. Larger connectors can better withstand occlusal forces and stress, which reduces the risk of failure or breakage during function.

Additionally, larger connectors provide a more resilient framework in the interim prosthetic, which is essential given that these restorations are often subject to significant wear and loading due to chewing and other oral functions. When the connectors are adequately sized, they contribute to the overall integrity of the prosthetic work.

While factors like material manipulation and occlusal clearance can influence the final restoration's performance, the structural design and size of the connectors themselves have a direct impact on the strength and durability of interim restorations, making this the most relevant factor in achieving increased strength.
