Alveolar ridge preservation following tooth extraction has the ability to maintain the ridge dimensions and allow the implant placement in an ideal position fulfilling both functional and aesthetic results. Postextraction socket healing commonly results in resorption of the alveolar ridge. To prevent this clinical situation, different authors have described several surgical procedures, ranging from regenerative techniques for socket preservation to immediate implant placement. Regenerative techniques have been widely tested in controlled and uncontrolled studies with various materials and clinical approaches: bone grafting alone, including autografts, allografts, xenografts, and alloplasts; membrane alone, whether absorbable or not; and membrane in conjunction with grafting.
