Augmentation of the Width and Thickness of Keratinized Gingiva Using a Collagen Biomaterial in Apically Positioned Flap Surgery: A Technical Note

To ensure that dental implants remain functional in the long-term, adequate thickness and width of keratinised tissue at the cervical collars are essential.[1] Once a tooth is lost, the height of the alveolar bone is reduced, and the keratinised tissue of the edentulous area recedes.[2] There are two techniques currently used to obtain the desired keratinised tissue augmentation: the apically positioned flap surgery and the free gingival graft surgery.[2] The apically positioned flap surgery, the existing keratinised tissue is incised at the mucosal or mucoperiosteal flap to enable natural extension of the incised end.
