A Novel Approach to Regain Anterior Space Using Modified 2 by 3 Fixed Appliance: A Report of Two Cases.

Early loss of permanent anterior teeth in growing children has a psychological impact on the child. Anterior teeth are important both aesthetically and functionally. When a permanent tooth is lost, the teeth adjacent to the created space tend to migrate into the space resulting in the space loss. Management of regaining space with the removable appliance always depends on child cooperation for using the appliance as well as for the recall visits. The advantages of fixed appliances over the removable appliances are minimal discomfort, reduced need for patient cooperation and increased control of tooth movements in all three directions of space. Thus, a short course of fixed appliance like the modified 2 by 3 fixed appliance followed by fixed functional space maintainer could be an ideal treatment option for such cases.
