INBDE Practice Exam 2026 – Complete Study Guide

The space maintainer used for primary second molar loss if the permanent molar has erupted is the LLHA or Nance. This is because the LLHA or Nance is a type of space maintainer that holds space on the side opposite of the lost tooth, in this case the primary second molar. The Distal shoe, Transpalatal arch, and Space regainer options do not address the specific situation described in the question and are therefore incorrect. The Distal shoe is used for early loss of primary first molars, the Transpalatal arch is used for midline deviation or crossbites, and the Space regainer is used for late loss of primary first molars.
