Which pontic design is MOST appropriate for the MAXILLARY FIRST PREMOLAR area (esthetic zone)?
Show answer and explanation
Correct answer: D. Modified ridge lap pontic
- A. Incorrect. The ovate pontic is the most esthetic option (sits in a prepared ridge concavity) but requires surgical ridge modification — the modified ridge lap is the standard esthetic choice without surgery.
- B. Incorrect. The saddle/full ridge lap pontic has the worst hygiene and is contraindicated despite good esthetics because of plaque accumulation.
- C. Incorrect. The sanitary pontic does not contact the ridge — while hygienic, it looks unnatural and is inappropriate for the esthetic zone.
- D. Correct. The MODIFIED RIDGE LAP pontic is the STANDARD CHOICE for the ESTHETIC ZONE (maxillary premolars and anterior teeth). It contacts the BUCCAL ridge only (providing natural appearance from the labial/buccal view) while the LINGUAL surface is concave and accessible for flossing. This balances esthetics with acceptable hygiene access.
