How deep does the vestibule need to be to have a lingual bar?

at least 7mm
at least 5mm
at least 10mm
at least 3mm

The correct answer is: at least 7mm

To have a lingual bar in a removable partial denture, the depth of the vestibule needs to be at least 7mm. This depth is necessary to provide adequate space for the lingual bar component of the denture and to ensure proper retention and stability of the prosthesis. Having a deeper vestibule allows for better support and distribution of forces when the denture is in place. This requirement helps prevent discomfort and potential issues with the fit and function of the removable partial denture. Options B, C, and D are incorrect as they do not meet the minimum depth requirement needed for a lingual bar to function effectively in a removable partial denture.
