Prosthodontics & Occlusion · single question
The patient chooses to have tooth #9 extracted and replaced with a 3-unit fixed bridge. What pontic design will provide the most natural emergence profile and allow the gingiva to form proper esthetic contours in this anterior area?
Show answer and explanation
Correct answer: C. Ovate pontic
- A. The modified ridge lap contacts the facial ridge only and is a common, adequate choice for anterior teeth but does not create as natural an emergence as the ovate.
- B. The full saddle/ridge lap wraps around the ridge on both facial and lingual — poor hygiene access; largely obsolete.
- C. CORRECT — The ovate pontic sits within a receptor site prepared in the ridge, mimicking a natural tooth emerging from the sulcus. It is the gold standard for esthetics in the anterior maxilla when adequate ridge height is present (or has been surgically/orthodontically preserved).
- D. The hygienic (sanitary) pontic has no tissue contact and is used only in posterior mandible where esthetics is not a concern.
