Prosthodontics & Occlusion · single question

A patient with an intracoronal attachment has a compromised connector. What procedure would help save the connector?

  1. Replace with extracoronal attachment
  2. Splinting the abutment teeth
  3. Increase occlusal loading
  4. Placement of a cantilever bridge
Show answer and explanation

Correct answer: B. Splinting the abutment teeth

  • A. INCORRECT. Converting to an extracoronal attachment changes the prosthetic design and does not specifically 'save' the existing connector — it replaces it.
  • B. CORRECT. Splinting the abutment teeth distributes the occlusal forces across multiple teeth, reducing the load on the compromised connector. This stabilizes the teeth, reduces mobility, and helps preserve the connector by decreasing the mechanical stress it must bear.
  • C. INCORRECT. Increasing occlusal loading would worsen stress on the connector and accelerate failure — the opposite of what is needed.
  • D. INCORRECT. A cantilever bridge concentrates stress at the abutment tooth and connector junction, which would worsen rather than help a compromised connector.
