Abstract

Background: Numerous surgical grafting procedures designed to reconstruct a partially toothless ridge or ridge defects have been described in the literature over the years. The procedures can be grouped according to the means used to increase the ridge such as soft and hard tissue augmentation procedures. To illustrate the different approaches to utilizing soft tissue augmentation, the following procedures will be discussed: Pedicle graft, Roll graft and Free graft procedures (Pouch graft, Interposition graft and Onlay graft procedure).
Description of the procedure: In interpositional graft procedures, there is no need to remove the epithelium from the surface of the donor tissue. If augmentation is required in both buccolingual and apico-coronary direction, part of the graft must be placed above the surface of the tissue around the recipient site. Some of the grafted connective tissue surfaces will be exposed in the oral cavity.
"Envelope" or partial thickness flap with relaxing incisions, is prepared on the vestibular surface of the defective area. An appropriate donor site is selected at the palate or in the area of the maxillary tubercle, and a free epithelial-connective tissue graft is harvested. If enlargement of the ridge height is not required, the epithelial surface of the graft is placed with the surrounding epithelium. The graft is sutured all over the tissue at the recipient site. The temporary bridge is positioned to serve as a reference when estimating the amount of tissue needed to fill the defect.
Outcomes: The newly formed granulation tissue during healing will make a border between the graft and the adjacent tissue, smooth and properly epithelialized. Edema, which occurs postoperatively, will help contour the ridge.
Conclusions: Class III ridge defects are a major challenge for the dentists, as the ridge needs to be enlarged in both vertical and horizontal dimensions. The combined procedures can be used successfully in such situation.
