Female patient, leucoderm, 11 years old, reported to the service of Maxillofacial Surgery and Trauma of the Hospital Municipal do Campo Limpo with the legal responsible complaining about some missing teeth. The intraoral clinical exam revealed a tumour-like development in the area of the left pre-maxilla associated with the absence of the elements 21, 22 and 23, and presence of the 61. Radiographic exams were requested based on the clinical data, and they showed a large radiolucent lesion in the left side of the maxilla associated with the elements 21, 22, and 23, which were all retained. The lesion presented an expansive growth that had overtaken the maxillary sinus reaching a certain proximity with the orbital floor through its superior limit. An incisional biopsy was performed aggregated with the installation of a decompression device. The histopathological result was compatible with a dentigerous cyst and the decompression device was sustained for 6 months. Then the second surgery approach was planned for the removal of the cyst and the elements associated to it. A removable partial prosthesis was made available to the patient. The combined treatment of decompression followed by the posterior surgical removal showed to be effective and secure by preventing bigger sequels and surgical complications.
