What kind of attachment is used when a sheath is added to the band?

Lingual arch
Band and loop
Space maintainer
Fixed retainer

The correct answer is: Lingual arch

When a sheath is added to the band, it is typically used in conjunction with a lingual arch attachment. The design of the lingual arch incorporates a wire that runs along the lingual (tongue side) of the lower teeth, providing a means to maintain space and prevent movement of the molars after the loss of primary teeth. The sheath enhances the stability and retention of the band, securing it more effectively to the archwire. The other options refer to different types of orthodontic appliances. A band and loop is more specific for single tooth space maintenance, while a space maintainer is a broader category that can include various devices but does not specifically suggest the addition of a sheath to a band. A fixed retainer is used to keep teeth in position after orthodontic treatment, but it does not involve a sheath that is added to a band. Understanding these differences emphasizes the unique function of the lingual arch with its associated band and sheath in orthodontic treatment.
