Comparative characteristics of materials for relining complete removable dentures as part of import substitution

Relevance . Partial and complete loss of teeth are among the most common dental diseases. According to WHO, up to 75% of the world’s population suffers from them. Complete and partial secondary adentia are complex diseases that have a negative impact on the digestive, endocrine and nervous systems, as well as disrupting many other areas of the patient’s life, including social. Objective . Study of the practical features of using different materials for clinical (direct) relining of removable denture bases, identifying their inherent positive qualities and disadvantages. Materials and methods . During the clinical study, a comparative analysis of materials for direct (clinical) relining of removable dentures was carried out in 3 groups of patients. A total of 45 people took part in the study. The following materials were used: Rebaron (GC, Japan), Rebase II (Tokuyama, Japan), Nolatek (Vladmiva, Russia). Results. It was established that the group of patients with prosthetic relining with Nolatek material showed the best clinical result. Conclusion . The data we obtained allows us to conclude that the modern domestic light-curing polymer composite material Nolatek for clinical relining has a number of operational and clinical-technological advantages over cold polymerization materials.
