“…By the seventh day, distinct formation of the lumina was observable. The formation of the vascular layer in the graft-bed junction, parallel to the bone, coincided with the first stages of the appearance of the bridging vessels as observed with dye-injected sections by Janson et al 10 However, they reported that it was impossible to determine whether the bridging vessels entered the graft or whether the regenerating vessels anastomosed with the existing ones in the graft. In the present study, employing three-dimensional observation techniques, it was made clear that vessel transformation commenced from the newly formed sinusoidal vessels.…”

Nobuto has previously reported on the initial anastomosis involved in establishing circulation between a free gingival autograft and the recipient bed. This study will present observations on the maturation of new sinusoidal vessels involved in maintaining circulation to the graft and the resulting histovascular organization. Using 56 mongrel dogs, the ongoing processes were observed periodically over 84 days after grafting. For this purpose, vascular corrosion casts were examined with the scanning electron microscope. At the same time, employing both light microscopy and transmission electron microscopy, histopathological and ultrastructural observation on the developing three-dimensional vascular architecture were recorded with supporting photographs. Thus, the entire process from the development of a vascular plexus parallel to the bone surface on the seventh day to the transformation to a vertical dendritic vascular architecture firmly establishing the circulation to the graft by the 84th day, is provided in both descriptive and pictorial detail.

“…A review of other potential causes of graft mobility deemed it necessary to examine the unques tioned acceptance of the statement that free autogenous gingival grafts should be placed on a recipient bed of periosteum and connective tissue. The rationale was that this aids in revascularizing the graft, 9,10,19,34,35 mini mizing osseous resorption, 36 and helping to obtain an uneventful sequence of events in healing. 19,36,37 A careful review of the histology of periosteum brings out several very relevant concepts.…”

1. Thirty free autogenous gingival grafts were placed on bone and 30 were placed on a periosteal bed. The distribution into the groups was random. All 60 grafts survived, showing that both procedures were predictable. 2. Over one-half (17 of 30) of those on periosteum demonstrated mobility by 6 months postoperatively. No mobility was observed in the group placed directly on bone. 3. Osseous placed grafts demonstrated less swelling and better hemostasis than did the periosteally placed grafts. 4. A healing lag was observed in the grafts placed on bone which lasted only for the first two postoperative visits, approximately 2 weeks. 5. No infections or sequestrations were noted in any case.

“…Thus, the ADMG has a unique healing process that differs from the connective tissue graft. Generally, the incorporation of the autograft is based on the anastomosis between the blood vessels of the gingival corium and those preexisting in the connective tissue graft; while the allograft, as an avascular and acellular material, depends exclusively on cells and blood vessels from the recipient site to achieve reorganization …”

Graft survival plays a decisive role in mucogingival therapy results and the selection of the appropriate surgical technique is important to achieve it. This 12-month randomized study showed that an extended flap is able to improve the results of root coverage of localized gingival recessions not only when using the acellular dermal matrix as shown in a previous study, but also when using the subepithelial connective tissue. On this basis, this surgical technique can be suggested as the procedure of choice for treating this type of defect.
