Study Notes
Factors Affecting Displacement
- Amount of displacement depends on the amount of pressure applied
- Amount of displacement depends on the nature of the mucosa (thickness)
Anatomic and Functional Ridge Forms
- Original mandibular cast shows the residual ridge area recorded in its anatomic form
- Buccal shelf region is outlined in the mandibular cast
Distal Extension Base
- Enhanced by intimacy of contact between the tissue surface of the base and the tissue that covers the residual ridge
- Affects the direction and magnitude of the occlusal load to the removable partial denture
- Affects the load transferred to the abutments
Residual Ridge Bone
- Nature of the residual ridge bone is a factor in displacement
- Positional relationship of the residual ridge bone to the direction of stresses that will be placed on it
