Minimally invasive soft tissue augmentation is a challenging problem for dentists. Use of autogenous fibroblast of oral mucosa is a promising method. The paper represents the results of preclinical, clinical and laboratory studies on the use of autogenous oral mucosa fibroblasts (AOMF) for gum recession correction. The results confirm statistically significant gum thickness augmentation and gum recession decrease after three weekly AOMF injections. The effect lasted for at least 9 months.
