Surface Evaluation of the Combination of a Nylon and Traditional Partial Removable Dental Prosthesis: 3.5-year Follow-up Clinical Report

Abstract

A nylon partial removable dental prosthesis (PRDP) is aesthetically superior to a traditional PRDP. However, the nylon surface becomes rough after long-term use.

There have been few clinical follow-up reports concerning the re-polished surface after long-term insertion of the nylon PRDP.

We observed the re-polished surface of the nylon denture base with a microscope and a contact profilometer.

This clinical report describes a PRDP constructed from a nylon denture base resin and a metal framework, which obtained a good prognosis during 3.5 years of use. The rough surface of the nylon was improved by re-polishing. However, the deformation of the nylon retentive arm and required relining impeded its long-term use.
