A saddle (full ridge-lap) pontic that broadly contacts the residual ridge on both the facial and lingual surfaces is discouraged because it:
Show answer and explanation
Correct answer: A. Creates a concave area that cannot be cleaned and promotes tissue inflammation
A full ridge-lap (saddle) pontic wraps tissue on both facial and lingual, creating a concave plaque-trapping surface the patient cannot clean, leading to inflammation. A modified ridge-lap pontic contacts only the facial for esthetics while keeping the tissue surface convex and cleansable.Other options: The problem is poor hygiene access, not esthetics; the saddle pontic is hard to clean and impedes flossing.Key exam takeaway: Use a modified ridge-lap pontic (convex, facial-only contact) for cleansability; avoid the full saddle/ridge-lap.
