What is the primary function of tissue stops in a denture base minor connector?

• A. Stabilize the framework during resin packing and processing
• B. Indicator for the fit
• C. Provide retention
• D. Improve esthetics

Answer: (A)

Tissue stops on a denture base minor connector act as positive seating guides during processing. They give the framework a defined resting position against the mucosa so that, as resin is packed and cured, the minor connector and base stay in the correct vertical place and the acrylic thickness around the connector remains uniform. This stabilizes the framework against processing forces and helps prevent distortion or shifting of the delicate minor connector. These stops aren’t primarily about retention or esthetics, and they aren’t used as indicators of fit. They serve the key role of maintaining stable, accurate seating during resin packing and processing.
