Patient of 50 years old referred to the Centre of maxillofacial surgery and dentistry of FSI Burdenko Central Military Clinical Hospital with complaints of absence of the 3 teeth in the 1 segment - 1.5, 1.6, 1.7. Teeth 1.5 and 1.7 were absent for a long period of time, while the tooth 1.6 was removed about six months ago due to exacerbation of chronic periodontitis. The removed tooth and tooth 1.4 were abutment teeth of a bridge. Thus a terminal dentition defect of the upper jaw in the position of teeth 1.5, 1.6, 1.7 appeared. The patient asked to implement a fixed prosthesis in this area.
