Abstract :Purpose This study aimed to evaluate whether horizontal continuous and apical stretching sutures could reduce FGG shrinkage. Materials and Methods In this randomized controlled clinical trial ten patients insert ignore into journalissuearticles values(20 sites, seven females and three males); ranging from 18 to 53 years insert ignore into journalissuearticles values(average 39 years); with insufficient keratinized and attached gingiva received FGG in two quadrants of mandible insert ignore into journalissuearticles values(splitmouth design);. Horizontal continuous and apical stretching sutures were used in test sites in addition to common suturing techniques. Clinical parameters including probing depth insert ignore into journalissuearticles values(PD);, the width of keratinized and attached gingiva insert ignore into journalissuearticles values(KG, AG);, the horizontal and vertical dimension of the graft insert ignore into journalissuearticles values(HD, VD);, and graft area insert ignore into journalissuearticles values(GA); were recorded at baseline and 1, 3, and six months after the operation. Results PD did not differ significantly for six months. The average change of other parameters in test and control sites respectively was as follows: KG increased 5.5 mm and 5.1 mm, AG increased 5.3 mm and 5.1 mm, HD shrinkage was 21.6% and 15.8%, VD shrinkage was 33.7% and 33.2%, GA shrinkage was 47.3% and 43.3%. There were no significant differences between test and control sites in clinical parameters six months after surgery. Conclusion Application of horizontal continuous and apical stretching sutures does not reduce FGG shrinkage.
