Dentistry is one of the most developing specialties in the field of 3D printing, and it is in orthopedic dentistry that not only the speed and accuracy of the manufactured orthopedic structures are most important, but also the properties of the materials used: safety; biocompatibility; compliance with medical. Despite the development of modern dentistry and the emergence of new basic materials for the manufacture of removable dentures, today, 98% of all removable plate dentures in the world are made of acrylate-based plastics. The article presents the results of a review of biocompatible photopolymer resins for the manufacture of removable dentures. The composition and characteristics of photopolymer resins and the stages of the polymerization process are described; a classification of biocompatible resins is presented. Analysis of the assortment of the Russian market of biocompatible photopolymer resins used in orthopedic dentistry for removable prosthetics showed that the main market share is occupied by only three companies producing these resins. The presented review of biocompatible photopolymer resins for removable prosthetics showed that today an active search continues in the field of developing modern base materials for the manufacture of complete removable plate prostheses with optimal characteristics.
