Which pontic design is WORST for oral hygiene?
Show answer and explanation
Correct answer: D. Saddle (ridge-lap) pontic
- A. Incorrect – contacts only the facial; cleansable lingually.
- B. Incorrect. A conical pontic has minimal tissue contact and is relatively cleansable; the saddle/ridge-lap pontic overlaps the ridge on both sides and is the least hygienic.
- C. Incorrect – this design is specifically the most cleansable (no tissue contact).
- D. Correct – it overlaps both facial and lingual of the ridge with a large concave tissue contact that cannot be cleaned; it is the least hygienic and is contraindicated.
