Which pontic design is MOST appropriate for edentulous areas in the posterior maxilla (upper molars)?
Show answer and explanation
Correct answer: C. Hygienic (sanitary) pontic
The hygienic (sanitary) pontic is the design of choice for maxillary posterior (molar) edentulous areas because esthetics is less critical in this region, and a completely tissue-free design allows maximum cleansability. The convex undersurface does not contact the ridge at all, eliminating plaque retention and tissue inflammation. In anterior or visible areas, a modified ridge lap or ovate pontic is preferred for esthetics.
- A. ❌ The modified ridge lap is preferred for anterior regions where moderate esthetics is needed without full ridge lap tissue contact.
- B. ❌ The ovate pontic is ideal for anterior esthetics (sits in a prepared tissue depression) but is not recommended for posterior molars.
- C. ✅ CORRECT – The hygienic (sanitary) pontic is preferred for maxillary posterior areas where esthetics is secondary to cleanability.
- D. ❌ The saddle/ridge lap pontic contacts the ridge on both buccal and lingual aspects — the worst design for hygiene and tissue health.
