The article presents the study of diagnostic methods and the use of autogenous connective tissue grafts
in surgical methods of treating Miller class I gingival recession.
As the results, in the period from 2020-2021, 33 Miller class I gingival recession zones were treated. The
height of gingival recessions before treatment averaged 3.5 ± 1.13 mm. Assessment of the level of
attached keratinized gingiva up to the cement-enamel junction of the tooth showed a significant (p
<0.001) increase after surgical treatment. The average percentage efficacy of recession coverage in the
study group was - 84%. Pain, fibrinous plaque and soft tissue edema were insignificant. The use of free
connective tissue autograft taken from the hard palate is an effective method of treating Miller class I
gingival recession.
