Healing Dynamics of Free Gingival Grafts; a Colorimetric and Volumetric Assessment

"A horizontal partial thickness incision will be trace at the MGJ to dissect the alveolar mucosa from the keratinized tissue. The alveolar mucosa will be dissected from the underlying periosteum to create an envelope of 4-5 mm apical to the bone dehiscence associated with the gingival recessions. The keratinized tissue coronal to the first incision and neighboring the recession will be de-epithelialized to expose the connective tissue and create a trapezoidal recipient bed having a large apical base at the MGJ and a narrower coronal base just coronal to the CEJ of the experimental units. The grafts will be taken from the palate.The grafts will be positionned with the coronal edge of the CEJ.~Interrupted sutures (6-0 polypropylene, prolene) will be positionned to stabilize the graft. Sling crossed sutures anchored to the periosteum apical to the graft and placed to ensure a tight adaptation of the graft to the root surface"
