socket preservation
A surgical technique using bone grafting materials to maintain alveolar ridge dimensions following tooth extraction.
Full Definition
Socket preservation, also known as ridge preservation or alveolar ridge preservation, is a surgical procedure performed immediately after tooth extraction to minimize bone resorption and maintain the original contours of the extraction site. The technique involves placing bone graft material, often with a barrier membrane, into the extraction socket to promote bone formation and prevent collapse of the facial and lingual walls. Common graft materials include allografts, xenografts, or synthetic bone substitutes. This procedure is particularly important when future implant placement is planned, as it helps maintain adequate bone volume and favorable ridge morphology. The technique significantly reduces the need for more complex bone augmentation procedures during subsequent implant surgery.
Usage
Usage note: Distinguish from immediate implant placement, which involves implant insertion at extraction.
