Techniques for coating recessions

Currently there are different techniques for coating recessions, such as: coronal flaps replacement, the tunnel technique, grafts or subepithelial free connective tissue being autologous connective with or without coating the technique of choice. However, these implants involves a second surgical field with consequent postoperative discomfort in the palatal area.

Biomaterials, such as three-dimensional collagen matrices, we get similar increase in both root coverage and attached gingiva results, allowing us to improve gingival biotype. This matrix has two layers: a dense which gives more stability and allows us to fix it with suture; and one which is porous and is in contact with the root. This last layer is colonized laterally by the blood vessels and increases in volume when filled with blood.

The matrix must be handled dry and should be seated on the cemento-enamel junction. The flap should cover 2 or 3 millimeters of the matrix, and the suture must press on the enamel, allowing the porous part allow blood to pool.

For the viability of the biomaterial is fundamental lack of mobility flap. The Mucograft reabsorbed between 15 and 20 days, appearing slight swelling at 30 days, since it is an immature tissue and should not brush until 6 weeks. At 3 months, the tissue is ripe with the appearance of rete pegs.


case Study

We present a young patient with bilateral maxillary first molars recessions caused by brushing trauma and large tooth sensitivity. The patient consulted us the ability to cover their recessions without connective graft and thus solve their hypersensitivity.

Initial situation as the recession in 1.6 and 2 mm of gingivainserted.
if recession
Initial situation with the recession far more pronounced in 2.6mesiovestibular.












After correcting his brushing technique patients techniques root coating, a graft connective and other matrices using collagen arises Mucograft. Once the patient explained the pros and cons of both techniques, it opted for the use of collagenous matrices. Langer flaps are made and modified Langer and 2.6 1.6. In the photographic sequence the surgical procedure and follow-up of the case is ten days, a month and a year, proving the stability and increased tissue volume.
