Abstract

When performing a tooth extraction, imminent collapse of the tissue by resorption and remodeling of the socket is a natural occurrence. The procedure for the preservation of the alveolar ridge has been widely described in the dental literatures and aims to maintain hard and soft tissues in the extraction site for optimal rehabilitation either with conventional fixed or removable prosthetics or implant-supported prosthesis.

  Fig. 1 Preoperative periapical radiograph demonstrating bone loss related to periodontal disease of the maxillary left 1st premolar necessitating extraction.

• 

  Fig. 2 Incision made following sectioning of the bridge and extraction of the failing abutment.

• 

  Fig. 3 Elevation of a full thickness flap exposing the extraction socket.

• 

  Fig. 4 Cortical perforations have been placed in the edentulous area on the buccal aspect of the ridge.

• 

  Fig. 5 The socket and buccal deficiency have been filled with osseous graft material.

• 

  Fig. 6 A Resorbable membrane has been placed covering the osseous graft.

• 

  Fig. 7 Primary closure has been achieved and the site has been closed with a sufficient number of sutures.

• 

  Fig. 8 Post-operative occlusal view following healing demonstrating a fuller buccal aspect of the ridge.

• 

  Fig. 9 Post-operative buccal view following healing.

• 

  Fig. 10 Radiograph following healing of the osseous graft. The prognosis has been benefited by resolving the osseous defect while improving the chances to receive an implant or conventional prostheses.
