General information, peri\u2010implant soft\u2010tissue parameters and complications were recorded. Cone\u2010beam computed tomography images at preoperative (T0), immediate postoperative (T1), post\u2010healing (T2) and the latest follow\u2010up (T3) were collected. Buccal bone width, height, bone distance (BD) and augmented bone volume (ABV) were assessed. Bone augmentation range was classified into inside\u2010contour (IC) group and outside\u2010contour (OC) group based on BD values. Factors influencing the augmented bone volume resorption rate (ABV%) were analysed.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>During the follow\u2010up period of 12\u201388\u2009months, the mean ABV% was 47.56%\u2009\u00b1\u200920.29%, predominantly occurring between T1 and T2.
