In interim restorations, how should the size of connectors be adjusted to reduce the risk of failure?

Increasing the size of connectors in interim restorations can significantly enhance their strength and durability, thereby reducing the risk of failure. Larger connectors provide a greater surface area for bond strength and distribute occlusal forces more evenly across the prosthetic component. This is crucial in interim restorations, which are temporary solutions that often endure high levels of stress during the healing phase or while waiting for final restorations.

Moreover, larger connectors can help in maintaining the integrity of the prosthetic during functional movements, reducing the likelihood of fracture or dislodgement. By contrast, smaller connectors may not adequately support the restoration under functional loads, leading to a higher chance of failure. Thicker and flatter connectors have their own advantages, but simply increasing the size is generally more effective in enhancing overall stability and resilience of the restoration during its temporary use.
