Elastic dental prostheses - Alternative solutions for patients using acrylic prostheses: Literature review

Abstract

Elastic dentures are prostheses made of thermoplastic material. This category includes: nylons, acetals, acrylic polymers, and acrons. Elastic prostheses have been recognized for several years; however, their properties are constantly being modified. In the opinion of the majority of patients, elastic prostheses are comfortable, handy and long-lasting. Elastic dentures are a good choice for esthetic reasons. They may be recommended for patients who do not accept clasps in framework dentures, but cannot afford dentures supported with precise elements or implant-based fixed appliances. Such dentures can be applied in masticatory organ rehabilitation in patients with increased absolute reflexes, especially retching. Furthermore, such features like size, construction weight or material plasticity and smoothness are considered to be advantages of thermoplastic materials. Elastic dentures are the only removable appliances for patients allergic to metal or acrylic. They are better tolerated by patients with an uneasy prosthetic base or with systemic diseases, e.g., diabetes, who are more susceptible to the traumatic activity of the hard plate of traditional dentures made of acrylic material. Adaptation time is shortened and the number of necessary corrections is reduced. Hygiene rules as well as follow-up visits terms must be strictly obeyed.
