The only way to restore the masticatory function in cases of complete edentulism is the placement of a total dental prosthesis. There are several options for its retention in the oral cavity and the easiest way is by using the simple plaque prosthesis. In cases of patients, who have lost all their teeth a long time ago, a severe atrophy of the alveolar crest is observed, which makes it difficult to retain and stabilize the prosthetic structure. This fact provoked us to look for a way to overcome this discomfort and provide normal chewing function in similar cases. The present article aims to present cases from our dental practice, which includes thermoforming technology in the fabrication of total dental prostheses. In order to achieve this goal literature sources were studied, an experiment was conducted, patients were observed, photographic material was collected and both patients and dentists were asked about the outcome of the experiment. It has been found that the fabricated total prostheses not only have very good aesthetics, but are also very stable during oral function and are steadily retained in the oral cavity.
