General information, peri‐implant soft‐tissue parameters and complications were recorded. Cone‐beam computed tomography images at preoperative (T0), immediate postoperative (T1), post‐healing (T2) and the latest follow‐up (T3) were collected. Buccal bone width, height, bone distance (BD) and augmented bone volume (ABV) were assessed. Bone augmentation range was classified into inside‐contour (IC) group and outside‐contour (OC) group based on BD values. Factors influencing the augmented bone volume resorption rate (ABV%) were analysed.ResultsDuring the follow‐up period of 12–88 months, the mean ABV% was 47.56% ± 20.29%, predominantly occurring between T1 and T2. The OC group showed higher ABV% compared to the IC group (<jats:italic>p</jats:italic> < 0.001). BD of the IC and 0–1 mm OC groups was less than 0, while BD of the 1–2 and > 2 mm OC groups was near 0 at T3. Bone augmentation range (<jats:italic>p</jats:italic> < 0.001), non‐contained defects (<jats:italic>p</jats:italic> = 0.001) and 2‐mm healing abutments (<jats:italic>p</jats:italic> = 0.008) significantly influenced ABV%.ConclusionsSimultaneous GBR with implant placement in the posterior mandible provided predictable volumetric stability of the augmented bone. OC grafts resorbed towards individual phenotypical dimensions, whereas 1–2 mm over‐augmentation might optimise contour maintenance. Non‐contained defects compromised volumetric stability, while the 2‐mm healing abutments enhanced stability compared to cover screws.","PeriodicalId":15380,"journal":{"name":"Journal of Clinical Periodontology","volume":"149 1","pages":""},"PeriodicalIF":6.7,"publicationDate":"2025-07-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144603083","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
