Egg shaped Pontic

# Egg-shaped pontic is indicated for the replacement of:
a) Mandibular posteriors
b) Mandibular anteriors
c) Maxillary posteriors
d) Maxillary anteriors

The correct answer is A. Mandibular posteriors.

In the mandibular posterior region where esthetics is not a major consideration, spheroidal pontic (egg shaped pontic) is the design of choice because of its contour.

In the maxilla, modified ridge lap design satisfies both esthetics and hygiene so it is the pontic design of choice in both anterior and posterior region.
