Dual appliance- space regainer and maintainer in same appliance

Primary teeth are need to stay in place till they are replaced by permanent teeth, so they are the best space maintainers. One of the main reasons for early extraction of primary teeth is be Early childhood cariesespeciallyin the anterior. So, any untimely loss of anterior teeth subsequently causes a) morphological problems- impaction and eruption disturbances of permanent successors; inclination and/ or extrusion of adjacent and antagonist teeth, respectively; midline deviation; and crowding b) functional problems; speech disorders, aesthetic problems, and development of non-nutritive habits c) psychosocial problems; decrease in self-esteem2. However, in some cases there can be a combination of problem like early loss of tooth leading to space loss and impaction of the erupting tooth so that calls for regaining the lost space and restoring the missing tooth till the permanent teeth replacement is done. This paper presents an innovative design incorporating both the treatment objectives in a single appliance: A dual appliance with dual treatment outcome.
