Alveolar ridge preservation

This study tested whether a gel made from chitosan (a natural substance) can better preserve the jawbone after a tooth is pulled, compared to letting the socket heal on its own. Twenty-six adults with at least one hopeless tooth in the back of the jaw participated. Researchers us…

This study tested whether using a patient's own extracted tooth as a bone graft (AMDG) works better than a synthetic material (β-TCP) or no graft at all for preserving the jawbone after tooth removal. Twenty-two adults who needed a maxillary premolar pulled received one of the th…

This study tested whether placing a thin bone layer (cortical lamina) over the extraction site helps preserve the jawbone's shape and size. Forty adults needing a tooth pulled were randomly assigned to get the lamina or standard care. After six months, bone changes were measured …

This study tested methods to prevent bone and gum shrinkage after removing a front tooth. Fifty-six adults were randomly assigned to standard extraction, extraction with a blood-and-bone graft, a technique that keeps a tooth root fragment (pontic shield), or the fragment plus gra…

This completed trial tested the Socket Shield Technique (SST), where a thin piece of tooth root is left in place after extraction to support the bone and gum around a dental implant. 25 adults needing a single front tooth implant were randomly assigned to get the implant right aw…

Researchers compare three ways to preserve the jawbone after a tooth is removed. Participants are randomly assigned to receive no bone graft, a graft made from their own extracted tooth, or a synthetic bone substitute called beta-tricalcium phosphate. The trial measures changes i…

This study tested two different materials used to preserve the jawbone after a tooth is pulled. Forty adults received either a cow-derived bone graft or a human donor bone graft. Researchers measured how much the bone changed in size and density over six months using 3D scans. Th…
