Correct answer: E — Modified ridge lap (ovate) pontic

The modified ridge lap (ovate) pontic is the ideal design for the aesthetic zone. It has a convex tissue surface that contacts the ridge on the facial aspect for aesthetics but is concave or convex lingually to allow cleaning. The ovate design sits in a soft tissue depression created on the ridge, giving the illusion of a tooth emerging from the tissue. Saddle (full ridge lap) pontics trap plaque and are not recommended. Sanitary pontics allow good hygiene but have poor aesthetics.
