Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
Bone grafting following tooth extraction is commonly performed to preserve bony ridge dimensions adequate to support subsequent implant placement. Alveolar ridge resorption commonly occurs following tooth extraction, and the decrease in bone volume has the potential to make dental implant therapy impossible without surgery to reconstruct the ridge. The aim of ridge preservation grafting is to prevent or minimize this resorptive process, thereby preserving an adequate volume of bone for implant placement. Ridge preservation generally involves placement of a particulate bone graft material in the tooth socket, followed by use of a membrane or similar substance over the socket entrance to contain the bone graft. Various grafting materials have been recommended for these ridge preservation procedures, including demineralized freeze-dried bone allograft (DFDBA). The timing of dental implant placement following ridge preservation procedures is controversial, and few studies have examined the effects of different healing time intervals between ridge preservation and implant placement. The purpose of this project is to evaluate the formation of new bone at a site where tooth extraction has been performed followed by grafting using DFDBA. Two different study groups are included, one having the dental implant placed 8-10 weeks after tooth extraction and ridge grafting, the other having the dental implant placed 18-20 weeks after extraction and grafting.
