Dentigerous cysts (DC) are the most common odontogenic lesions of inflammatory origin in the mixed dentition. DC can be treated by enucleation, which requires extraction of the involved impacted teeth or decompression. Decompression is preferred because it allows preservation of the developing permanent teeth associated with the cyst and allows normal eruption. In January 2023, 9-year-old male patient with swelling in the right lower mandibular region was admitted to the Department of Pediatric Dentistry at Akdeniz University. Clinical/radiographic examination of the patient revealed unilocular radiolucent lesion associated with primary teeth 84-85. Teeth were extracted under local anesthesia, biopsy sample was taken from the lesion. In the same session, removable acrylic appliance with drainage channels was designed from the impression taken by conventional methods. The patient irrigated the lesion with saline twice a day while the appliance was in the mouth. At the end of the first month, radiographic reduction in the size of the lesion was observe. After nine month, 44 had settled into the normal position. Researchers commonly prefer decompression for the treatment of DC. However, the use of silicone drains significantly reduces the child's comfort during the procedure. Therefore, it was planned that the patient whose decompression treatment had been completed would use the same appliance as space maintainer until the premolars erupted. The use of removable drainage acrylic appliances that can be modified as space maintainers in the healing process of the lesion, increases comfort, reduces the need for orthodontic treatment in subsequent periods are significant results.
