The correct approach involves holding the metal base frame against the abutment tooth while the impression is setting. This process is crucial because it ensures that the indirect retainers, which are part of the removable partial denture (RPD), are in the proper position relative to the supporting teeth. When the impression material is setting, maintaining contact between the base frame and the abutment tooth helps to capture the correct spatial relationships and ensures that the indirect retainers will be adequately supported in the final restoration.

Achieving this stability during the impression-taking process contributes significantly to the accuracy and fit of the denture. If the retainers do not properly engage the teeth during this phase, it may lead to poor retention and stability of the RPD once completed.

Other methods would not effectively achieve that aim. For example, asking the patient to bite firmly could inadvertently alter the position of the framework or the impression material, leading to inaccuracies. Fabricating a new denture would not be the initial step any clinician would take if the current framework could be adjusted. Likewise, adding impression material to close any gaps does not address the need for accurate positioning of the indirect retainers during the setting of the impression. Hence, maintaining proper support of the framework against the
