The authors have made full removable dentures for 60 patients with total secondary toothlessness and various types of ringe bone atrophy of both jaws: in 30 cases using face bows and articulators and in 30 cases in accordance with standard practice using occludators. Three months later, they run a masticatory test by I.S. Rubinov. In the first group, with adaptation to removable dentures for 2 weeks, the chewing efficiency was 85% and the chewing time increased by 4 sec. In the second group the figures were 78% and 8 sec., respectively, but the adaptation to dentures lasted for 4 weeks.
