Clinical outcomes of a peri-implant keratinized mucosa augmentation procedure using concentrated growth factor: a prospective case series

Within the limitations of this case series, our findings suggested that the use of ARF combined with CGF could be a reliable approach for keratinized mucosal augmentation and vestibular deepening. KMW achieved the clinically ideal value of more than 2 mm one year after surgery. Histological analysis revealed the formation of keratinized mucosa around the implants.
