Background:To uncover evidence of whether immediate implant placement (IIP) significantly reduces horizontal ridge shrinkage?
Materials and Methods:Electronic searches (1980 to September 2021) were performed by two reviewers using PubMed, MEDLINE, and Cochrane Central.
Results:Findings suggested that IIP using flap-less surgery, atraumatic extraction, 3D positioning, gap grafting with xenograft and customized healing abutments may limit shrinkage similarly to that with socket preservation grafting and delayed implant placement (SPG/DH).
Conclusions:Further randomized, clinical trials directly comparing IIP and SPG/DH will be needed for confirmation
