What is a possible danger of performing a functional reline of RPD?

Performing a functional reline of a removable partial denture (RPD) involves making adjustments to the base of the denture to ensure it conforms more closely to the underlying oral tissues. While the goal is to improve fit and function, there is a potential danger that comes with this procedure, namely the movement of the framework.

This framework is crucial as it provides the necessary support and stability for the dental prosthesis. If a functional reline is not executed properly, it can lead to undesirable movements of the framework. Such a movement can compromise the retention and stability of the entire prosthesis, leading to discomfort for the patient and potentially affecting the occlusion and overall function of the denture. This highlights the importance of precision in the reline process to ensure that the fit remains secure and that the integrity of the framework is preserved.

The other options relate to possible improvements or benefits resulting from the reline, such as enhanced fit, occlusal relationships, or border extension; however, without adequately addressing the potential for framework movement, these benefits could be overshadowed by instability in the RPD, underscoring the critical focus on maintaining framework integrity during any adjustments.
