This case report describes the predictable coverage of multiple adjacent maxillary gingival recessions using the modified coronally advanced flap (MCAF) technique and modified coronally advanced tunnel technique (MCAT) in conjunction with an acellular porcine-derived collagen matrix (mucoderm(r)) combined with enamel matrix derivative (Straumann(r) Emdogain(r)).
Next, the collagen matrix was placed over those exposed root surfaces exhibiting the most prominent recessions (teeth #12 and #13) and immobilized at the level of the cementoenamel junction with palatal sling sutures (Fig. 7).
The tunnel was then prepared using tunneling knives, and the collagen matrix was rehydrated for 10-20 minutes.
Next, the collagen matrix was pulled into the tunnel with the help of vertical mattress sutures (Figs.
The case presented here illustrates the successful coverage of exposed tooth roots with simultaneous thickening of the marginal tissue using a less invasive approach by applying the collagen matrix mucoderm(r) in combination with Emdogain(r).
