[00:00:00]In a 10-year-old child, premature loss of extracted primary second molars caused the space to begin closing. The rest of the occlusion is normal. What is the treatment plan? A, band and loop. B, lingual arch. C, complete banding of first molar. D, none of the above.

[00:00:18]Let's check the answer. B, lingual arch.

This bilateral appliance connects the left and right first permanent molars.

Even better, it can be adjusted to generally push molars back and rescue that lost millimeters. It's the ultimate set it and forget it hero for saving room for those future premolars.
