Freeze-dried skin (FDS) allografts and fresh autogenous free gingival grafts (FGG) were placed in five paired sites in four patients. Both types of grafts healed uneventfully. Evaluation over a 1-year period demonstrated no statistically or clinically significant differences between the FDS and FGG when: a) increase in the width of keratinized gingiva, b) decrease in recession, c) decrease in sulcus depth, k) gain in attachment level, or e) percent shrinkage of the graft were compared. It was concluded that 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.
将冻干皮肤（FDS）同种异体移植物和新鲜自体游离龈移植物（FGG）置于4例患者的5对部位。两种类型的移植物均愈合良好。在1年的观察期内，当比较以下指标时，FDS和FGG之间在统计学或临床上均无显著差异：a）角化龈宽度增加，b）退缩减少，c）龈沟深度减少，k）附着水平增加，或e）移植物收缩百分比。得出的结论是，在治疗黏膜牙龈问题方面，FDS的表现与FGG基本相似，并且具有降低患者发病率（无供体部位）以及在需要时可获得大量移植物材料的优点。
