Which condition may result from a flexing bar in an implant-supported overdenture?

The option indicating the flexing of the bar as a result of a flexing bar in an implant-supported overdenture is the correct choice. When a flexing bar is utilized, it is designed to accommodate the forces exerted during function. However, if the bar is not adequately supported by the implants or if there is excessive force applied—perhaps due to improper occlusion or insufficient support from neighboring structures—it may result in the bar itself undergoing flexion or deformation.

Understanding this dynamic is crucial, as excessive flexing of the bar can not only compromise the integrity of the prosthetic restoration but also affect the distribution of forces to the supporting implants, ultimately leading to potential complications over time. Such issues can manifest as discomfort for the patient and may necessitate adjustments or redesign of the bar to ensure optimal performance of the overdenture and the health of surrounding structures.

Regarding the other conditions mentioned, improper occlusion might contribute to excessive forces that could cause flexing, but it is not a direct result of the flexing bar itself. Bone resorption and soft tissue irritation may also occur due to ongoing stress or complications from a poorly functioning prosthesis, yet these are secondary effects and not outcomes directly caused by the flexing of the bar.
