[The morphometric characteristics of the masticatory muscle of dogs with an expanded interalveolar space].
The experiment with 24 dogs involved increase of their interalveolar space in the frontal section by 6 mm via fixation of metal crowns on 98 189 teeth. Follow-up of the masticatory muscle adaptation has shown that it ran a wave-like course. The most intensive shifts are observed on days 7-14 of the experiment, this being followed by a gradual recovery of this muscle tinctorial characteristics by the 20th day of the experiment; then the restructuring process stabilizes on a new structural and functional level by days 30-60 of the experiment. Complete morphologic restructuring of the masticatory muscle in response to increase of the interalveolar space takes more than 60 days. If a still more increase of this space is needed (more than 6 mm), it may be started not before 20-30 days after complete restructuring.
