Simplified Technique in Removable Complete Prosthesis Versus Conventional Technique in Edentulous Patients

This study compares a simplified complete removable denture technique (PS) to the conventional approach (PC) in edentulous patients. The goal is to demonstrate that the simplified technique is not inferior to the conventional method in terms of quality of life, measured by the OHIP-20 scale over three months. The trial also examines time, satisfaction, denture quality, cost, and masticatory performance. Design: This is a multicenter, randomized, cross-over study with 62 patients over 11 months of participation, including a one-month washout between treatments. Patients will receive both types of dentures, with the order randomized. Population: The trial targets edentulous patients, both uni- and bi-maxillary, aged 18 or older, with certain health and dental conditions. Key Assessments: Quality of Life: OHIP-20 scores are collected pre-treatment and after three months for each denture type. Patient Satisfaction and Denture Quality: Assessed using modified Kapur criteria and patient satisfaction surveys. Masticatory Performance: Evaluated with a chewing gum test. Medical Economic Impact: Cost analysis of each denture type. Anticipated Outcomes: Benefits include reducing costs and treatment times, enhancing accessibility to dentures, particularly for elderly and underserved populations, and adapting dental education to teach this simplified technique. Centers Involved: Seven centers across France, including AP-HP hospitals and private practices. Timeline: The inclusion period is 24 months, with a total study duration of 35 months.
