Summary

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?

Conditions

• Gingival Recession

Interventions

Type	Name	Description
PROCEDURE	Inverted T shape Free Gingival Graft	the preparation of the recipient site commenced by making a horizontal incision at the mucogingival junction (MGJ) as well as two vertical incisions extending to the adjacent teeth and about 3-4 mm beyond the MGJ. A sharp split-thickness flap will be reflected, and the surfaces between these incisions will be de-epithelialized. Also, all the surfaces of the interdental papilla up to the lingual side will be de-epithelized using a 15c blade and microsurgical scissor .(Harvesting of the palatal donor site will be designed 2 mm away from the gingival margin using a template in the form of an inverted T-shape, taking into consideration the position of the greater palatine blood vessels at 5 mm. 2 mm is required for the width of the interproximal extension with 3 mm length to obtain an even thickness of 1-1.5 mm . Placement of the graft : The Inverted T FGG will be inserted between the teeth to cover interproximal tissue defect and sutured lingually into the lingual marginal gingiva
PROCEDURE	Free Gingival Graft	Preparation of the recipient site :Following an intrasulcular incision, 2 mm-long horizontal incisions at the level of the CEJ will be performed bilaterally. From these, vertical releasing incisions will be placed in a diverging manner, extending well into the alveolar mucosa, a thin partial thickness flap will be subsequently raised then excised. The dimension of the resulting site will be measured to obtain a rectangular foil template . Harvesting of the Graft :Using the foil template, graft dimensions will be outlined in the palate adjacent to the premolars and first molar. A partial thickness graft consisting of epithelium and a thin layer of underlying connective tissue will be harvested (intended total thickness of graft: 1.5 mm), maintaining a distance of ≥2 mm to the maxillary teeth.
