A utilização de enxertos para o tratamento de recessões gengivais: relato de dois casos clínicos.

Abstract

Gingival recessions, in addition to aesthetic impairment, may be associated with dentin hypersensitivity and the difficulty in mechanical biofilm control. Among the possibilities of treatment, there is the root coverage with the use of grafts. The objective of this study was to report two clinical cases of Miller class II gingival recessions treated with the use of grafts. Patient A.A.J, male, 23 years old, had a gingival recession in the region of the tooth 31. An envelope flap was made in said region, where a subepithelial connective tissue graft from the patient's palate was accommodated. Patient, P.A.G, female, 23 years old, had gingival recession, also on tooth 31, with fine periodontal biotype. A partial thickness flap was made in the region of teeth 41 to 32 and the area was covered with a free gingival graft. Case 1 was followed 7 and 30 postoperative days, with partial recoating of the gingival recession, with a gain of 2 mm of tissue. In case 2, on the seventh day, extensive necrosis of the graft was observed. The necrosed area was removed by curettage, and in the subsequent evaluations, on the 15th and 30th days, area healing was observed without additional necrosis, and an increase of the keratinized gingiva band, with a gain of 1 mm of tissue. Both patients reported being satisfied with the results obtained. It is concluded that, although the subepithelial connective tissue graft is more esthetic, both treatments promote a gain of the keratinized gingival band in height and thickness.
