Correct answer: E — A crown specifically designed and contoured to provide optimal survey line position, guide planes, rest seats, and undercuts for RPD clasp engagement
A surveyed crown is a fixed restoration (crown or onlay) specifically designed and fabricated with features to optimise RPD design: a favourable survey line position, properly located retentive undercuts (of correct depth for the planned clasp type), prepared guide planes, rest seat preparations, and appropriate contour for reciprocal arms. The surveyed crown is designed on the surveyor simultaneously with the RPD framework design, ensuring harmonious fit. This is especially important for abutment teeth that require restorative treatment.
