Harvesting good-quality connective tissue grafts (CTGs) is important in periodontal surgery. Compared with CTGs, free gingival grafts (FGGs) have a slower healing process and higher donor site morbidity. As far as graft quality and anatomic limitations are concerned, deepithelialized free gingival grafts (DE-FGGs) are superior to CTGs. In the current study, a modified combined approach is proposed that aims to address the disadvantages of conventional FGG harvesting methods. This approach entails harvesting a thin and narrow DE-FGG, repositioning the epithelial layer, and applying a plastic stent. The outcomes of this improved method indicate fast healing at the donor sites, fewer postoperative complications, and better esthetic results at the recipient sites.
获取高质量的结缔组织移植物（CTG）在牙周手术中很重要。与CTG相比，游离龈瓣移植（FGG）的愈合过程较慢，供区发病率较高。就移植物质量和解剖学限制而言，去上皮游离龈瓣移植（DE-FGG）优于CTG。在本研究中，提出了一种改良的联合方法，旨在解决传统FGG获取方法的缺点。该方法包括获取薄而窄的DE-FGG，重新定位上皮层，并应用塑料支架。这种改进方法的结果表明，供区愈合快，术后并发症少，受区美学效果更好。
