Among those who joined efforts in the study of these problems were scientists such as professors Ya.S. Utshtem, M.S. Nemenov, M.О. Kovarsky, N.M. Vilnik, and A.I. Yevdokimov, who replaced M.В. Yankovsky at the post after his death in January 1923. A.I. Yevdokimov made large contributions of his own in the SID's development and that earned him the titles of Honored Scientist of the Russian Federation, a corresponding member of the Academy of Medical Sciences of the USSR and of Hero of Socialist Labor. Another new name, that of the State Institute of Stomatology and Odontology (SISO) was given in April 1927 by decree of the Sovnarkom (the Soviet government). The SISO was to continue the job of training dentists through a specially organized refresher course for dental professionals and a dental specialization course for general medicine faculties. This helped to streamline the public dental health care as well as carry on with scientific research in the fields of dental and oral pathology and therapy, maxillofacial surgery, orthodontics, and prosthodontics. In 1932, the SISO was renamed yet again, this time to the State Research Institute of Stomatology and Odontology (SRISO) and from then on it was concerned mostly with scientific research problems. There were no educational departments in it at the time, those having been replaced by newly formed divisions for pathological physiology, morphology, surgery and social dentistry instead, to which a steel prosthetics laboratory was added. Another, central, laboratory for prosthetics research was set up a year later in 1933 to manufacture steel dentures on a large scale. The Moscow Stomatological Institute (MSI) as a higher dental school was established under the Narkomzdrav's order dated June 9, 1935, as a subdivision within the SRISO's framework. Both institutions were housed in one building, sharing administration, finances and facilities. Thus, the MSI became the only institution in the Russian Soviet Federal Socialist Republic (RSFSR) that was to conduct scientific research in dentistry, translate the results obtained into everyday dental care practices and train dental professionals as well. Since 1935 a whole number of departments were being added to the institute those of normal anatomy, biology, general chemistry, histology, embryology, and, finally, in 1937 the departments of oral therapy, oral surgery and prosthodontics.
