[Extension of the gingival zone with grafts of hard palate mucosa in the treatment of deep periodontal pathology].

In 28 patients aged 25 to 54 years (mean 34.5 years) with the diagnosis of deep parodontopathy the gingival zone was extended in the mandible from one to the cotrolateral canine tooth using grafts of hard palate mucosa. In the initial and in the control examinations the width of the attached gingiva, the depth of the vestibule, the depth of the gingival pouches and the denudation of roots were measured. The clinical status of the parodontium was evaluated using the indices GI, GBI, PI, the index of teeth mobility R of Focke, the X-ray index EMR, and the oral hygiene index OHI. In all patients after the treatment permanent widening of the gingival zone was observed with a significant improvement of the mean values of the analysed parameters.
