Abstract:

Patients with removable partial dentures have to clean and maintain their constructions. Evaluation of the impact of different denture cleansers on the mechanical and physical properties of the materials used for the fabrication of these removable dentures is important, because they affect not only the aesthetics of the construction but also its longevity and function. Thermoplastic polyamides, also known as nylons, have recently become more popular in treating partially edentulous patients with removable partial dentures.
Aim. The aim of the current review was to evaluate and compare the effect of different denture cleansers on the properties of nylon denture base materials.
Materials and methods. A literature review was conducted using PubMed, Web of Science, Google Scholar, and others including scientific papers up to February of 2025. There was no restriction on the date of publishing and language of publications. The keywords used for conducting the search were combinations of the following: “nylon dentures”, “flexible dentures”, “polyamide”, “physical properties”, “mechanical properties” and “denture cleansers”.
Conclusion. According to the results of the studies, the mechanical and physical properties of nylon-based, flexible polyamide can be altered depending on the immersion time and type of denture cleanser. The majority of authors find that these changes are within clinically acceptable ranges. Patients and dental professionals should remain vigilant, ensuring proper cleaning practices and monitoring for any long-term impacts, with further research needed to solidify these findings.
