Flexible resins: an esthetic option for partially edentulous patients

Flexible thermoplastic resins have been used as an alternative to partially edentulous patients for decades in the USA. However, they are neither popular nor widespread in Brazil. This material represents an excellent treatment option to solve clinical problems such as compromised esthetics caused by visible metal clasps, and fall fracture of dentures made of conventional resins. Additionally, there is little researching and no controlled clinical studies about the use of flexible resins in prosthodontics. For these reasons, this study presents a case report of a dissatisfied patient treated with a conventional removable partial denture, which was replaced by a modified metal framework without metal clasps in combination with flexible resin, and a literature review about this material focusing on the dental practitioner. The study also reports how these polymers can be used, their indications, and their clinical and laboratory considerations.
