The study was performed on 21 edentulous patients, treated during the period of 2017 - 2018 at the Surgical Dentistry Department at the Moscow State University of Medicine and Dentistry. The patients underwent the procedures of bone augmentation, dental implant placement, and placement of various design temporary dentures for the periods preceding the placement of the permanent implant-supported dentures. The authors have developed and implemented a medical-prophylactic device - an acrylic partial denture supported by temporary dental implant and Klammer fixation on the existing crowns in front of the edentulous area. The results of the use of the device during the post-operative period were analyzed and compared to those of traditionally designed removable partial devices. The comparative analysis has shown that the medical-prophylactic device is superior to the temporary removable partial dentures and vacuum-formed retainers.
