Abstract
Thermoplastic materials are used more and more in the technology of complete or removable partial dentures due to their superior qualities. We have tested an acetal resin, two polyamide resins and polyamide prefabricated clasps. By injection, we have manufactured several removable partial dentures without metallic structure. Thermoplastic resins are suitable for manufacturing a wide range of removable partial dentures without metallic structure, in optimal conditions of biocompatibility. Key words: removable partial dentures, thermoplastic materials, molding-injection devices
