Soft Tissue Closure of Grafted Extraction Sockets in the Posterior Maxilla: The Rotated Pedicle Palatal Connective Tissue Flap Technique

The sequelae of socket collapse and localized ridge resorption after tooth extraction in the posterior maxilla can adversely affect esthetics, function, and future implant placement. Immediate grafting of extraction sockets may help to preserve natural ridge contours; but lack of available soft tissue can prevent primary closure or exert tension that hampers graft turnover and compromises the visible gingival scallop. Exposed barrier membranes may also be susceptible to bacterial infection that may lead to secondary graft failure. The rotated pedicle palatal connective tissue flap is a relatively simple technique for soft tissue coverage of grafted sockets without excessive tension. This article presents the technique.
