The conventional complete denture has disadvantages such as multiple visits to the dental clinic, including definitive impression and intermaxillary relationship records after taking preliminary impressions and making individual trays and reduced adaptation of the denture base due to the shrinkage of the heat-cured resin. The MAGIC Denture system (Cozahn, Seoul, Korea) requires only a few visits because of intermaxillary relationship records and definitive impression at the first visit and has reduced shrinkage after additive manufacturing of 3D printing. In this case, a 3D-printed denture by MAGIC Denture of Cozahn was manufactured, which required a minimum number of visits for a patient who had difficulty in treatment due to poor cooperation and intended to determine the clinical usefulness. The patient was satisfied with the functional and aesthetic aspects after the final denture was delivered.
