Inverted T -Shape Free Gingival Graft
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
Free Gingival Graft
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.
