The most difficult and time-consuming step in the free gingival graft (FGG) for keratinized mucosa augmentation is the compression suture anchoring the FGG to the periosteum. In this article, a novel “microscrew with tie-down sutures” technique was proposed to anchor the FGG to the recipient site without the traditional trans-periosteum suture. This patient’s keratinized mucosa width (KMW) around the healing abutments of teeth #29 and #30 was less than 1 mm. After an apically positioned flap (AFP) was prepared, two microscrews were placed at the buccal plate of the alveolar ridge bone, which is the coronal margin of the AFP. Then, the sutures winded between the microscrews and the healing abutments to anchor the FGG. In conclusion, the “microscrew with tie-down sutures” technique offers a feasible and simple alternative for the trans-periosteum compression suture, particularly in situations when the periosteum is fragile, thin, or injured.
