Abstract

Aim & Background: Traditional complete denture protocols typically involve several patient appointments and multiple laboratory procedures. However, various workflows integrating digital technology can streamline the process, enhancing speed and predictability. This technical case report represents a digital denture duplication process.

Case Description: The 67-year-old male patient diagnosed with mild dementia presented with well-formed edentulous ridges and a history of maxillary and mandibular complete dentures. Due to his medical condition, he required a backup set. A reliable and efficient method involving extra-oral scanning, printing trial dentures, a functional impression, and scanning of trial dentures followed by 3D milling was used to replicate the existing dentures with minimal discomfort. The patient expressed satisfaction regarding retention, stability, and aesthetics.

Conclusion: This case demonstrates the effectiveness of digital technology in meeting the needs of elderly and cognitively impaired patients, providing a practical solution for maintaining denture function and aesthetics.

Clinical significance—Digital technology provides the advantage of faster turnaround times for denture duplication, which is particularly beneficial in managing the needs of dementia patients who may require quick adjustments or replacements due to their condition.
