Construction of biodentaplast upper partial removable protection of biodentaplast by the bredent system (ThermoPress 400)

Abstract

The need for improved bioscience, function and aesthetics requires the use of thermoplastic materials in dental prostheses. The difference between acrylic plastics and thermoplastic materials is that the thermo-materials are polymerized under factory conditions and we get them in the form of granulates. For this reason, they do not contain a residual monomer. Partial removable prostheses are not fixed rigidly to the natural teeth of a patient. This means that the patient can remove and put the prosthesis himself, if necessary. This type of prosthesis rests on the mucous membrane and connects with the natural teeth with a variety of support elements. The purpose of this article is to present the technological steps of making an upper partial prosthesis from Biodentaplast material on the Bredent system (thermopress 400) on a real-life case. We present a case study involving a male patient, aged 56, who started in May, 2017. His partial teeth were third class by Kennedy (distal bilateral narrowing defect). Biodentaplast is a thermoplastic material based on polyoxymethylene with a high degree of crystallinity and is universally used in dentistry for the manufacture of non-metallic structures. The high-tech material is characterized by its hardness, elasticity, bio-portability and lightness. Some of the conclusions drawn are that thermoplastic dentures are useful in patients who have contraindications for dental scarring (epilepsy, acute joint diseases, etc.). A survey conducted among patients shows that 100% of respondents prefer flexible dentures to conventional PMMA plastics. Biological tolerance is high due to the lack of residual monomer and metal.
