Abstract
Background: Traditionally, a series of steps have been carried out to make a complete denture, which are still essential despite technological advances. However, in some patients it is difficult to adapt new dentures. Objective: To describe a simplified technique for the duplication of total dentures using thermo-cured acrylic. This technique seeks to preserve intraoral mechanoreceptors and muscle adaptation that a patient has managed for years with the old dentures. Case description: A patient with severe bone resorption in both jaws needed to change 20-plus-year-old dentures. Duplicators similar to 3i® were made to obtain copies similar to the patient’s dentures. Simultaneous impressions of both jaws with closed mouth were taken. The definitive thermo-cured dentures similar to the patient’s old ones maintained neurosensory physiology and the patient did not feel the change. Conclusions: Conservation of the sensory receptors such as cold, pressure, heat and muscle activity is essential for success in cases of denture duplication. The author has around 2500 cases of denture duplication in a more than-20-year practice.
