What is a potential implication of missing proximal contacts on interim restorations?

Missing proximal contacts on interim restorations can lead to tooth migration because the contacts between adjacent teeth provide a stabilizing effect by preventing movement. When these contacts are absent, the teeth may experience unopposed forces or a lack of resistance, allowing them to drift or migrate into the space created by the missing contact. This not only affects the alignment of the teeth but can also lead to further dental issues, such as food impaction, periodontal disease, or the complexity of future restorative procedures.

Having good proximal contacts is essential in maintaining the position and stability of teeth in their respective arches. This is especially important in interim restorations, which play a crucial role in the transitional phase before final restorations.
