What is the main advantage of a non-rigid (stress-breaking) connector in an RPD?
Show answer and explanation
Correct answer: C. Better stress distribution / protecting abutments
- A. ❌ Non-rigid connectors may slightly reduce overall stability — stability is not their advantage.
- B. ❌ Non-rigid connectors do not primarily enhance retention.
- C. ✅ Correct. Non-rigid connectors allow controlled movement between segments, REDUCING STRESSES transferred to periodontally compromised abutment teeth. This protects the abutments and distributes forces more favorably — the primary clinical advantage.
- D. ❌ Support is provided by rests, not the non-rigid connector.
