Which factor does NOT influence tooth-tissue support?

Tooth-tissue support refers to how effectively a removable partial denture (RPD) is supported by both the teeth and the surrounding tissues in the mouth. Among the factors listed, the design of the RPD, occlusal force, and denture base adaptation all play critical roles in determining how well the RPD distributes forces and interacts with the oral environment.

The design of the RPD dictates how it engages with the remaining teeth and tissues. It influences factors such as the areas of stress distribution and stability of the denture. Ensuring that the design is appropriate for the specific anatomical features of the patient significantly impacts the effectiveness and comfort of the RPD.

Occlusal force affects the load placed on the denture and the supporting structures. Excessive forces can lead to movement of the denture or discomfort, while proper occlusion ensures that the forces are evenly distributed, enhancing the stability of the RPD.

Denture base adaptation is crucial for achieving good fit and function. A well-adapted base minimizes movement during function, providing better support by maximizing contact with the underlying tissues.

In contrast, the patient’s age is not a direct factor influencing tooth-tissue support. While age may result in changes to bone density or oral health
