Associação de técnicas cirúrgicas para recobrimento radicular de recessão classe III: relato de caso.

Abstract

The aim of this study was to report a case of surgical treatment of gingival recession Class III Miller. Female patient, L. L. A., 44 years old, presented with a 7mm gingival recession with no apical keratinized mucosa in relation to the recession. The patient reported having hypersensitivity to cold and hot, pain and ulceration of the alveolar mucosa to tooth brushing. It was noted initially the free gingival graft surgery to create keratinized mucosa in the apical region of the recession, aimed at preventing the progression of the defect and foster care in the region. The gingival graft promoted the formation of 4mm keratinized mucosa and overlaid 3.5mm of bare root surface, corresponding to 50% of the recession. As there was the formation of a good range of keratinized mucosa adjacent to the recession after the free gingival graft technique and the defect was not completely covered, it was decided to move laterally the flap in order to improve the prognosis of recession. After the technique of laterally positioned flap, there was an increase of 1mm keratinized mucosa and attached gingiva. However, no additional root coverage. Despite the low predictability of the results for root coverage on a Class III Miller gingival recession, the free gingival grafts presented to provide predictable root coverage, and especially increased keratinized tissue, favoring the prognosis of the tooth with this recession class.
