Why is it important to smooth rough edges on an RPD?

Smoothing rough edges on a removable partial denture (RPD) is crucial for improving the comfort of the patient. Any rough or sharp edges can lead to irritation or injury to the oral tissues, which may result in discomfort during wear. Patients need to feel comfortable while using their dentures for extended periods; jagged edges can cause sores or ulcers on the gums or other soft tissues of the mouth. By ensuring that the margins and surfaces of the RPD are smooth, you create a more pleasant experience for the patient, facilitating better wear tolerance and encouraging consistent use of the prosthesis.

While other factors, such as aesthetic appearance and ease of cleaning, are relevant to the overall function and satisfaction of the RPD, the primary concern focused on patient comfort directly addresses the immediate impact on their daily experience wearing the denture.
