Abstract
Freeze-dried skin (FDS) allografts and fresh autogenous free gingival grafts (FGG) were placed in 5 paired sites in 4 patients. Both types of grafts healed uneventfully. Evaluation over a 1 yr period demonstrated no statistically or clinically significant differences between the FDS and FGG when the following were compared: increase in the width of keratinized gingiva; decrease in recession; decrease in sulcus depth; gain in attachment level; or percent shrinkage of the graft. FDS performs essentially similar to FGG in the correction of mucogingival problems, and has the advantages of decreased patient morbidity (no donor site) and availability of abundant amounts of graft material when needed.
