What is the primary reason for using a provisional restoration?

The primary reason for using a provisional restoration is to maintain tooth position. Provisional restorations serve as temporary replacements for lost or prepared teeth, ensuring that the remaining teeth do not shift or drift into the space created by the missing tooth or the tooth preparation process. This is critical because positional changes in teeth can complicate the final restoration and affect occlusion and esthetics.

While provisional restorations can also have roles in managing discomfort and providing an aesthetic appearance temporarily, their most crucial function revolves around maintaining the spatial relationship of the remaining teeth and preventing undesirable movements. This ensures that when the definitive restoration is placed, there is a proper fit and alignment with adjacent and opposing teeth. Therefore, the focus on tooth position aligns well with the fundamental goals of provisional restorations in dentistry.
