Gingival Recession Treatment: Guided Tissue Regeneration Versus Connective Tissue Graft

Objectives:Various Procedures have been proposed to treat Gingival Recession including subepithelial Connective Tissue Graft (SECTG) and Guided Tissue Regeneration (GTR) but few studies have compared these procedures. The purpose of this study is to attempt a clinical comparison of SECTG (a modified Technique) and GTR with a “collagen membrane and space maker” in treatment of gingival recessions in humans Methods: Twenty –four defects were treated in 21 patients suffering from canine or bicuspid buccal Recessions according to Miller class I or II. Clinical measurements were obtained at baseline and 1-2-3-6 month after surgery. These clinical measurements included gingival recession depth (RD), recession width (RW), probing depth (PD), clinical attachment level (CAL) and width of keratinized tissue (KT). Results: Both SECTG (Modified technique) and GTR with a bioabsorbable membrane and space maker demonstrated significant clinical improvement for gingival recession treatment. The SECTG group was statistically significantly better than GTR group for RW (SECTG = 3.67 mm, GTR = 1.95mm, P=0.0005), CAL (SECTG = 4.08mm, GTR = 0.83mm, P=0.0001), RD and PD were statistically similar in both groups RD (SECTG = 3.45mm, GTR = 2.96mm, P=0.07), PD (SECTG = 0.5 mm, GTR = 0.37mm, P = 0.3) The two procedures were statistically similar in root coverage (SECTG = 100%, GTR = 82%, P = 0.073). Conclusion: Both SECTG (modified technique) and GTR with bioabsorbable membrane and space maker may predictably cover gingival recession. However SECTG is superior for RW, CAL, KT.
