[Cytological studies of the gingiva in endonseous extension implantations]

In addition to radiographs and clinical diagnostic-methods, exfoliative cytology can be used as a testing method for the evaluation of implants. The simple and gentle method of sample taking permits regular follow-ups. While in the area of stable grafts a normal cytogram is obtained, the cytogram of the area of loose grafts shows all the signs of inflammation on the cellular level: "a shift to the left", low indices of keratinization and eosinophilia, cellular alterations, presence of bacteria, leukocytes, and lymphocytes.
