Recobrimento de recessões radiculares associadas a lesões cervicais não-cariosas. Enxerto de tecido conjuntivo X matriz de colágeno suíno. Relato de caso.

Abstract

Gingival recessions are exposures of the root surfaces that occur due to apical migration of the gingival margin, which may present a poorer treatment prognosis if associated with non-carious cervical lesions. The gold standard treatment for this type of condition is the use of connective tissue graft associated with coronal replacement of the flap after restoration of the root surface. However, the use of autogenous grafts is associated with discomfort for patients during the postoperative phase, and their harvesting requires operator skill. The use of porcine collagen matrix is an option for treating gingival recessions, with the advantage of reducing morbidity related to the procedure. The present study aims to report a clinical case of root coverage involving bilateral mandibular premolars. The patient presented in the third quadrant, elements 34 and 35, respectively, presented the following measurements: Probing depth (PD) = 2 and 1; Marginal Gingival Level (MGL) = 2 and 2; Clinical Attachment Level (CAL) = 4 and 3; Keratinized Mucosa Height (KMH) = 2 and 1; Keratinized Mucosa Thickness (KMT) = 1 and 1, in the fourth quadrant, the measurements, respectively, of teeth 44 and 45, were: PD = 2 and 1; MGL = 1 and 2; CAL = 3 and 3; KMH = 1 and 1; KMT = 1 and 1. After the draw, it was designated that the 3rd quadrant would receive the connective tissue graft, coming from the Hard Palate, the 4th would receive the collagen matrix graft of porcine origin. It was possible to demonstrate that both sides presented similarly satisfactory results, both aesthetically and functionally. Therefore, it is possible to infer that, in this case, the xenogenic mucosal substitute was effective in root coverage surgery.
