Another lingual arch appliance for mandibular bilateral space maintenance is shown here. In this case, the appliance is attached to permanent teeth.

The mandibular lingual arch space maintainer is used very commonly in the primary dentition and the mixed dentition, where bands can be cemented to primary or permanent molars respectively. This is one of the most ubiquitously used space maintainers. It is even used on occasion in the permanent dentition when bicuspids are missing and maintaining space is necessary prior to orthodontic and/or prosthetic therapy.
