Extraction, Grafting with Bicon Resorbable Collagen Membrane, Placement and Restoration of immediately functioning Maxillary Right Central Incisor Implant with an Integrated Abutment Crown™
This case demonstrates the extraction of a failed endodontically treated maxillary right central incisor and its restoration with an immediately functioning implant and an Integrated Abutment Crown™ six months after the grafting of its extraction site with a Bicon Resorbable Collagen Membrane and an allograft material.

The extraction site being carefully curetted to remove granulation tissue and soft tissue tags.
7.
Vertical incision being made lateral to osseous defect in the buccal cortical plate.
8.
Full thickness flap elevated on facial with mesial and distal vertical incisions placed so as to provide a margin of sound bone for placement of the membrane. If possible, incisions are placed to avoid trauma to the interproximal aspect of the papillae.
9.
A large defect is evident in the buccal cortical plate.
10.
Allograft filling defect to the width of the buccal cortical plate, and to the height of the interproximal bone. Graft material can be bovine, porcine, human or inorganic.
11.
Bicon Resorbable Collagen Membrane cut to size and placed so that its margins extend onto surrounding bone on its mesial, distal, and apical borders. On the palatal aspect the membrane is tucked under the palatal tissue in direct contact with the palatal bone.
12.
The palatal tissue can usually be elevated with a periosteal elevator without using additional vertical incisions on the palatal aspect. However, if there is difficulty tucking the membrane under these tissues, small mesial and distal incisions may be helpful.
13.
Closure of the tension free flap with vicryl sutures. In order to achieve primary closure, the facial flap was apically undermined by creating a split thickness flap and advancing the flap coronally.
