What space maintainer is used for primary first molar loss if the permanent molar is erupted?

Band and Loop
LLHA or Nance
Distal Shoe
Fixed Unilateral

The correct answer is: Band and Loop

The Band and Loop space maintainer is typically used for primary first molar loss when the permanent molar has already erupted. A Band and Loop appliance consists of a band that is placed on the molar and a loop that is attached to the band and wraps around the adjacent teeth. This maintains the space for the permanent molar to erupt into. The other options, LLHA or Nance, Distal Shoe, and Fixed Unilateral, are all used for different purposes and may not be suitable for maintaining the space in this scenario. LLHA or Nance is typically used for maintaining space in the anterior region, Distal Shoe is used when there is no permanent molar present, and Fixed Unilateral is used when there is a combination of primary and permanent teeth present.
