Connective-tissue grafts.
These are sometimes required in Dental Implant Surgery to facilitate adequate volume and contour of the appearance of the gums around your implants. Having a nice smile is affected not only but the colour, shape and position of your teeth but also by the colour, shape and volume of the gum tissue also on view in your smile.
During the procedure, a flap of the mucosa is raised in the roof of your mouth (palate) and then soft tissue from under the flap, called subepithelial connective tissue, is removed and then stitched/placed under the mucosa around the dental implant where volume is required. It is quite common at the Oral Facial & Implant Centre to perform connective-tissue grafting to provide the optimum cosmetic appearance for your smile.
Free gingival grafts. Similar to a connective-tissue graft, free gingival grafts involve the use of tissue from the roof of the mouth (palate or maxillary tuberosity) but instead of making a flap and removing connective tissue from under the flap, a small amount of the whole thickness of the tissue is removed and then sutured to near the implant area to support the natural soft tissues present in that location. This method is used most often in people who have thin gums to begin with and need additional tissue to enlarge the gums.
