Prosthodontic treatment for edentulous patients with microstomia is a challenge because of the constricted opening of the oral cavity. This clinical report presents the prosthetic management of an edentulous maxilla in a patient with burn-induced microstomia. A sectional maxillary complete denture was fabricated. With the use of a custom-made inlay structure at the overlapping metal base along the palatal midline, the sectional prosthesis was successfully and easily inserted and provided adequate function in the patient's mouth.
