简要总结
Inadequate ridge width to allow implant placement, it noted that when extraction takes place and ridge preservation is not utilized the site of extraction could lose 40% to 60% of bone height and width within 2 to 3 years and subsequent loss of 0.25% to 0.5% annually. it reported as much as 4 mm loss of ridge width in extraction alone sites within 6 months. Using an atraumatic tooth extraction technique preserves osseous walls thereby improving the chances of osseous graft success.
The goal of ridge preservation is minimizing bone loss to preserve the maximum final, healed ridge dimensions.
Socket preservation is done using a hard tissue graft like xenograft bone or synthetic bone substitutes and prevent hazard of surgical intervention which needed during implant loading due to bone resorption.
详细描述
Good assessment whether a particular graft is more beneficial than others which can be improve the extraction site healing.
Good assessment if grafting has any beneficial or detrimental effects on post-operative sequelae post extraction.
Extraction is indicated when a tooth cannot be restored or maintained in suitable conditions for long-term health, function, and/or esthetics. Loss of a tooth has a direct effect on life quality by impairing the ability to masticate, speak, and, in some instances, socialize, after tooth extraction an average alveolar bone loss of 1.5-2 mm (vertical) and 40%-50% (horizontal) occurs within 6 months, alveolar dimensional changes occur during the first 3 months. If no treatment to restore the dentition is provided, then continued bone loss occurs and up to 40%-60% of ridge volume is lost in first 3 years . And the absence of a tooth in its alveolus enhances a cascade of biological events that typically result in significant local anatomic changes..
Studies have demonstrated that loss of alveolar ridge Post extraction is an irreversible process result in both horizontal and vertical reduction. Atrophy of alveolar ridge may have a significant effect on tooth replacement therapy, especially when implant restorations are planned.
Therefore, alveolar ridge preservation has become a key component of contemporary clinical dentistry.
