Introduction: The simple anterior cross-bite, which describes an occlusion defect between upper and lower incisor
teeth, is a serious condition that can prevent the sagittal jaw development and cause attrition, gingival retraction and
mobility of affected teeth if not treated in early time. The aim of this case report is to present the treatment of two
simple anterior cross-bite cases using removable appliances with posterior bite-blocks and Z-springs.
Case Report: Patients referred to our clinic with complaints of dental caries and crowding. Cross-bites were seen in
the maxillary left central incisor tooth of the 7-year-old female patient and the maxillary right central incisor tooth
of the 7-year-old male patient in the first and second cases respectively. The removable appliances with posterior
bite-blocks to eliminate over-bite along the treatment and Z-springs to move the teeth which in cross-bite were
made for both patients. The patients were shown how to use the appliances and told the importance of using them
regularly. In both cases, the treatment lasted in 20 days.
Discussion: The usage of removable appliances in the treatment of simple anterior cross-bites has many advantages
such as short procedure time, ease in placing, removing and cleaning, being cheaper than fixed appliances.
Conclusion: If the patient`s cooperation is sufficient, anterior cross-bites can be successfully treated with
removable appliances in a short time.
