Bone regeneration in extraction sites. Part 1: The simultaneous approach

Implant placement in an extraction site is a frequent procedure in oral implantology. The concept of guided tissue regeneration to restore the alveolar ridge has expanded the available options for treatment of complicated cases. Implants can be placed in an extraction site at the time of surgery, and 3 to 4 weeks or 8 to 12 weeks after extraction in the simultaneous approach with guided bone regeneration. Four cases of implants placed in defective extraction sites with simultaneous guided bone regeneration are presented. Timing, surgical management, and complications are described.
