Palatal Volumetric Change Analysis Following Connective Tissue Graft With and Without Donor Site Augmentation

The randomized controlled trial aims to investigate the potential effect of post-harvesting donor site augmentation on palatal volumetric changes following connective tissue graft harvesting. The study investigation is a randomized controlled trial (RCT) that aims to have 20 participants in each group. The palatal thickness will be clinically assessed and a digital intraoral scan of the palate will be performed pre-operatively. A subepithelial connect tissue graft will then be harvested from the palate. Patients will then be randomly assigned to receive/not receive augmentation of the donor site, using a collagen sponge. Palatal thickness measurements and intraoral scans will be repeated at 2-, 4-, and 6-months postoperatively.
