Problems solved by technology

[0002] Removable partial dentures (RPDs) have been an effective method for repairing dentition defects for nearly a century. However, due to the complexity of metal brackets for removable partial dentures, they are still mainly produced by traditional manual lost-wax casting techniques at home and abroad. The production process is cumbersome and complex, prone to various errors, and highly dependent on the technician's clinical experience and production skills
