Guided Bone Regeneration Around Immediate Implants
Completed · Phase 4
Conditions studied: Missing Tooth
In brief
An important result of healing after tooth extraction is a reduction in dimensions of the remaining bone at that site. This reduction of bone volume precludes successful restoration of the space using a dental implant. Bone augmentation has shown promise in clinical reports to reduce this loss of bone volume, thus allowing implant placement and restoration. The purpose of this study is to evaluate the clinical and radiographic outcomes of guided bone regeneration around dental implants placed in fresh extraction sockets.
