Abstract:
In cases where a palatal defect resulting from oral cancer surgery is reconstructed using a free flap, dentures placed on the grafted site, lacking bone support, may experience stability problems due to insufficient support. This case report presents a 41-year-old male patient who underwent a sinus resection due to maxillary sinus carcinoma. The defect was reconstructed using a lateral thigh free flap.After a three-month interim prosthesis phase, a conventional removable partial denture was fabricated. Considering the condition of the remaining teeth and the patient’s age, natural tooth alteration was performed and lingual undercuts of the right posterior teeth were incorporated into the design to compensate for the lack of bone support. Digital occlusal analysis devices and 3D facial scanning were utilized to evaluate changes in occlusion and facial form, and the visualized results were presented to the patient to enhance understanding.
