تونل جابهجاشونده به سمت کرونال تغییریافته
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)).
To treat the recessions in the region #22 to #24, the modified coronally advanced tunnel (MCAT) approach (Azzi & Etienne, 1998) was chosen.
Thus, to cover Miller class I and II multiple recession cases, if a satisfactory amount of keratinized gingiva is available apically to the recession, then MCAF and MCAT represent predictable procedures if used with the combination of mucoderm(r) and Emdogain(r).
Recently published studies on the treatment of maxillary Miller class I and II recessions using the modified coronally advanced tunnel (MCAT) technique in conjunction with the collagen matrix suggest that mucoderm(r) is a valid alternative to the autologous subepithelial connective tissue graft (SCTG) (Cieslik-Wegemund et al.
In the case of a thin biotype, the tunnel technique (MCAT) may be preferred, as it does not require splitting of the flap and the mucoderm(r) can be placed in direct contact with the bone.
