A tooth is extracted via a low‐trauma technique to maintain intact bony walls and surrounding gingival anatomy without flap reflection. The extraction socket is grafted up to the alveolar crest with an anorganic bovine bone substitute, covered with a collagen plug, and sutured in place with a horizontal mattress suture. A removable or fixed provisional restoration with an ovate pontic extending 3–4 mm subgingivally is placed, compressing the collagen plug and supporting the surrounding soft tissue. This technique has also been described in combination with immediate implant placement and with a buccal defect, whereby the defect is first lined with a collagen membrane.
