Relapse is when the teeth return to the position before orthodontic treatment. The small gaps between teeth often occur due to relapse conditions. A removable appliance is an orthodontic appliance that the patient can remove and insert themselves. This aims to report a relapse case treated using removable orthodontics. The case, A 26-year-old female patient complained of upper front teeth being gapped and lower front teeth being crowded. Previous dental history showed that the teeth had been treated with a fixed orthodontic appliance one year ago with premolar extraction. The patient did not use a retainer. The removable orthodontic appliance used was an active plate that retracted the maxillary anterior teeth using a labial bow. Orthodontic relapse can occur due to incomplete remodelling. Retraction using a labial bow can close the anterior teeth palatally. Active plates can be used as an alternative treatment in mild cases of relapse after fixed orthodontic treatment
