Abstract
Patients: A 69-year-old male patient visited our dental office with the chief complaint of discomfort caused by his complete dentures. Intraoral examination revealed that both mandibular and maxillary ridges appeared to be good and to retain the dentures although he had a habit of tongue-thrusting. The existing dentures were duplicated and used as treatment dentures in this case. New complete dentures were fabricated by referring to the duplicated dentures.
Discussion: The duplicate dentures method, in which dentures can be reversed after modification, enabled the duplicated dentures to be actively modified to reduce the patient’s sense of resistance to the new dentures.
Conclusion: The application of duplicate dentures appeared to be useful in the process of replacing the existing dentures with new dentures.
