Introduction: Crossbite is defined as an abnormal labiolingual or buccolingual relationship between maxillary and mandibular teeth when the teeth of both arches are in occlusion. It can be further defined to specify the location in the mouth i.e. whether anterior or posterior and also whether a single tooth or groups of teeth are involved. Case report: In this case report we discuss 2 cases in which single tooth crossbite is treated with the help of fixed z-spring. Treatment is completed in the time interval of 10-15 days. Discussion: Dental anterior cross-bites involve a single tooth or multiple teeth and can be classified as a simple orthodontic problem. Early management of cross-bite in the deciduous or early mixed dentition is advocated to allow for spontaneous correction of succedaneous teeth. There are many treatment modalities for an anterior crossbite. These range from simple removable appliances incorporating springs or screws to the use of protraction masks in the anterior region. One of the best treatment options for anterior cross-bite patients is Z-spring. It can be given to the patient as a fixed or re- movable appliance. Conclusion: It is desirable to investigate further the extent to which the various aetiological factors that contribute to crossbite for better management of the cases of cross bite. The crossbite should be treated as soon as possible so that future orthodontic problems can be avoided.
