What is it about?
A randomized controlled trial was conducted to determine the efficacy of alveolar ridge preservation (ARP), which consisted of socket grafting with a bone biomaterial and sealing the socket orifice with a barrier, compared to tooth extraction alone. The effect that certain anatomical features play in the outcomes of therapy was also assessed. Data was collected on the basis of a comprehensive panel of outcomes (clinical, linear and volumetric dimensional changes, implant-related and patient-centered) over a four-month period after tooth extraction. The results demonstrated that ARP was superior to extraction alone, as it was more efficacious in the maintenance of alveolar bone and reduced the estimated need for additional bone augmentation at the time of implant placement.

Why is it important?
It is common to lose a significant amount of alveolar ridge volume in the first three to six months after a tooth extraction. Performing a ridge preservation procedure at the time of tooth extraction can preserve much of the natural architecture of the bone after an extraction, minimize the detrimental effects of tooth loss, and reduce the need for additional bone grafting to allow for implant placement.
