Minimizing Alveolar Ridge Shrinkage Following Immediate Implant Placement: A Literature Search and Narrative Review

Background: To uncover evidence of whether immediate implant placement (IIP) significantly reduces horizontal ridge shrinkage? Materials and Methods: Electronic searches (۱۹۸۰ to September ۲۰۲۱) were performed by two reviewers using PubMed, MEDLINE, and Cochrane Central. Results: Findings suggested that IIP using flap-less surgery, atraumatic extraction, ۳D 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
