The palatal masticatory mucosa between the canine and first molar is the main source of connective tissue graft (CTG) for use in periodontal plastic surgery. The purpose of this study was to evaluate the palatal augmentation technique (PAT) to increase the palatal connective tissue donor area using a collagen sponge inserted between the palatal flap and bone. The 26 patients enrolled in this study were referred for root coverage and ridge augmentation procedures. All patients lacked adequate donor palatal tissue thickness. The PAT uses a full thickness flap and bone. The palatal thickness was clinically assessed before and after collagen sponge insertion. A Manual probe was inserted in the mucosal surface perpendicular to the long axis of each tooth approximately 6mm from the gingival margin. Probing depth and recession were also recorded. Treatment with PAT resulted in a statistically significant increase in the palatal thickness.
