When repairing a fracture of a lower complete denture, what is a possible complication?

When repairing a fracture of a lower complete denture, occlusal disharmony can indeed arise as a significant complication. This situation occurs when the alignment of the teeth is altered due to the repair process, leading to improper contact during biting and chewing.

The occlusal plane may be affected if the alignment of the teeth is not carefully reestablished during the repair. If the teeth do not come together properly, patients may experience discomfort, inefficient chewing, and other functional issues. This underscores the importance of ensuring that the occlusion is checked and adjusted after a repair to maintain the proper function of the denture.

While other complications can occur, such as material shrinkage during the repair process or a color mismatch between the repaired area and the existing denture, they do not directly impact occlusion as critically. Excessive rigidity can also be problematic, but it primarily affects the overall comfort and adaptability of the denture rather than immediate occlusal function. Therefore, occlusal disharmony is the most relevant complication when considering the implications of a fracture repair in this context.
