The Clinical Effects of Using Collagen Matrix in Papilla Augmentation: a Prospective Clinical Trial. Augmenting Fibro-Gide in Interdental Area Using Tunneling Technique to Treat Black Triangles (Papilla Loss)

"collagen matrix augmentation in papilla area using tunneling technique, up to my knowledge, it's the first time to use collagen matrix in treating papilla, in less invasive approach, only though tunneling with no primary and secondary incisions.~so, the technique is designed to be less invasive, maximizing papillary blood supply.~and to use xeno collagen matrix instead of connective tissue graft used in previous study. so \~ less morbidity, less postoperative pain with no Donar graft site ."
