Why is it crucial to remove flabby, moveable tissue before the fabrication of dentures?

Removing flabby, moveable tissue before the fabrication of dentures is essential primarily because it ensures that the denture has a firm base. When the tissue is mobile or flabby, it can compromise the stability and retention of the dental prosthesis. A firm base allows the denture to sit securely on the oral tissues, preventing movement that can lead to discomfort, sore spots, or improper fit during regular use.

Additionally, a stable foundation aids in accurate impressions, ensuring that the dentures are constructed to fit the underlying anatomy of the patient’s mouth precisely. This attention to the contour and firmness of the tissues involved is pivotal for the long-term functionality and success of the dentures.

While aesthetic appearance, patient comfort, and manufacturing time are all important factors in denture fabrication, the primary focus here is the need for a reliable and secure foundation that mobile tissue cannot provide.
