Inverted T-shape Free Gingival Graft for Treatment of RT2 / RT3 Gingival Recession Defects

Inverted T-shape Free Gingival Graft Versus Free Gingival Graft for Treatment of RT2/RT3 Gingival Recession Defects : a Randomized Clinical Trial

The aim of this study is to compare the use of T-inverted shape Free Gingival Graft with Free Gingival Graft for improving the clinical attachment, gain partial root coverage, and improve Keratinized tissue width in recession type 2 /recession type 3 gingival recession defects .

Research question : In patients with RT2 / RT3 mandibular defects will the use of inverted T-shape free gingival graft differ from free gingival graft in Recession depth?

Inclusion Criteria:

• Patients with RT2/RT3 gingival recession.
• Indication for FGG treatment at mandibular incisor area (i.e., difficulty or discomfort during oral hygiene; gingival margin mobility; high muscle attachment and/or frenum pull; shallow vestibule and gingival recession.

• Ages 18-40 years old.
• Patients with healthy systemic condition (Brightman. 1994).
• Gingival and plaque index <10.
• Good oral hygiene (Wiesner et al. 2010).
• Accepts 6 months follow-up period (cooperative patients)

Exclusion Criteria:

• Smokers.
• Poor oral hygiene.
• Patient with a physical disability that hinders the upkeep of good oral hygiene measures.
• Intake of any medications known to affect gingival homeostasis or to interfere with wound healing.
• Pregnant or lactating women.
• RT1 gingival recession.
• Caries or non-carious cervical lesions at recipient sites.
• Severely malpositioned teeth.
• Teeth with residual probing depth ≥ 4 mm.
• Mobility ≥ 1 mm.
• Pervious periodontal surgery within the last 6 months before the start of the trial.
• Patients with active periodontal disease. -
