Lingual holding arch

# A mandibular lingual holding arch with loops mesial to each molar band is used in children for:
A. Correction
B. Regaining space
C. Space maintenance only
D. Correction of distally tilted molars 

The correct answer is B. Regaining space.

Normal passive mandibular lingual holding arch is used for space maintenance in mandible. This is  a preventive procedure.

Lingual arch with U loops mesial to each molar band is a modification of mandibular lingual arch. The loops are opened periodically and this can bring about distalization of molars by 1 to 2 mm. This is an interceptive procedure.
