What is the main benefit of allowing adequate material in a temporary crown?

Allowing adequate material in a temporary crown ensures that it can withstand occlusal forces effectively. Temporary crowns are designed to protect the prepared tooth while the permanent crown is being fabricated, and they may be subject to significant biting and chewing pressures. By ensuring that the material is thick enough, the temporary crown gains strength, stability, and durability, thereby reducing the risk of fractures or dislodgement. This structural integrity is crucial, especially in posterior teeth, where the occlusal forces are typically greater. In essence, maximizing the amount of material used enhances the temporary crown's ability to function properly and protect the underlying tooth structure until the final restoration is placed.
