Which pontic design CANNOT be used in the maxilla because it affects phonetics?

Correct answer: A. Hygienic (sanitary) pontic

• A. Correct. The hygienic (sanitary) pontic design has a gap between the pontic and ridge to facilitate cleaning, but this gap disrupts airflow during speech, making it unsuitable for the maxillary anterior region where phonetics matter most.
• B. The ridge lap pontic contacts the ridge for esthetics and does not create the same airflow disruption.
• C. The conical pontic design contacts the ridge in a small area and does not significantly disrupt phonetics.
• D. The ovate pontic design sits into a soft tissue contour for excellent esthetics and does not disrupt phonetics, making it actually ideal for anterior maxillary sites.
