Abstract

Prosthodontic treatment of a patient with a burdened allergic history by 3D milled complete removable prosthesis was performed. Materials and methods. The clinical case of treating a patient with a full adentia on the lower jaw and allergy to the used earlier acrylic prosthesis. Computer simulation of the prosthesis was carried out in the Exocad program. Removable prosthesis has been fabricated on a 3D milling apparatus with 5 micron precision from non-monomer containing polymethylmethacrylic discs. Results. The manufacture of the prosthesis was carried out according to an individual method by milling individual sections of the base and teeth, which made it possible to individualize the height of the base and choose a shade for the teeth for better aesthetics. The algorithm for designing the dentition is similar to that used in traditional methods of prosthetics. By combining the milled base and teeth, the final complete removable denture was obtained. Conclusion. The technique eliminates the release of residual monomer from the prosthetic bed to the mucous membrane, and also prevents injection molding errors such as shrinkage, gas porosity, and compression porosity. The use of a milled full denture allows you to restore the integrity of the dentition and eliminate all manifestations of allergic reactions, as well as their complications. Digital technologies reduces visits to the clinic. The use of milled prostheses is very promising in patients with a burdened allergic history.
