Implant–Buccal Plate Distance as Diagnostic Parameter: A Prospective Cohort Study on Implant Placement in Fresh Extraction Sockets

Background: The aim of this study is to investigate contour changes around immediate implants in fresh extraction sockets when different grafting procedures are performed, based on the distance between the external implant collar and the bony surface on the buccal plate (I‐BP). A secondary aim is to assess the esthetic outcome via the implant esthetic score (IAS). Methods: This prospective cohort study was performed in three centers. Suitable patients to undergo implant placement in fresh extraction sockets were selected. Periodontal biotype, horizontal and vertical peri‐implant bone defects, and dehiscences were assessed. Depending on I‐BP, two types of grafting procedures were performed. In group A (I‐BP
