A modified Nance appliance for space management and single tooth anterior crossbite correction: Case series

Abstract

Early loss of deciduous teeth can cause the drifting of teeth reducing the space available for the eruption of permanent successors and thus maintenance of space is critical to prevent malocclusion. At times, multiple decayed teeth can occur simultaneously with a single-tooth anterior crossbite, which is a major functional concern to the dentist and esthetic concern to the parents during the developmental stage of a child. Hence, there is a need for an appliance that can cater to both conditions of space management and anterior crossbite correction concurrently. The following case series focuses on the time taken and the comfort of the patient and for the correction of crossbite using a Modified Nance palatal appliance. All three cases took an average of 1 week for crossbite correction and patients showed superior comfort and compliance.
