1. Free gingival autograft = give by miller
2. Free connective tissue autograft = LEVINE
3. Laterally positioned flap = GRUPE AND WARREN
4. Semilunar coronally positioned flap = TARNOW
5. Subepithelial CTG = LANGER
6. GTR = PINE AND PRETO
7. Pouch and tunnel technique = AZZI 

Laterally positioned flap

1. TO COVER isolated areas of recession around a single tooth 
2. Adequate vestibular depth 
3. Variant = double papilla flap
4. Disadv = compromised blood supply 

Coronally positioned flap 

1. To cover 2-3 mm of recession 
2. Done on multiple teeth 
3. Best for maxillary anterior teeth
4. Pt who have Thick gingival biotype = Good prognosis 

Semilunar coronally positioned flap

1. Used to cover recession of 1 mm 
2. Slight recessions in anterior regions 

Subepithelial CTG 

1. Large and multiple areas of recessions 
2. NELSON graft = better blood supply = bilaminar or subpedicle CTG 

GTR

1. Maxillary area only 
2. 5mm recessions = more than 4.98 mm 

POUCH AND TUNNEL = It allows for CREEPING REATTACHMENT of marginal gingiva.
