A CBCT was taken before tooth extraction (T0), when the definitive restoration was placed (T1), and 1\u00a0year after placing the definitive restoration (T2). The depth and width of the dehiscence at T0, and the height and width of the facial hard and soft tissues are measured at the implant site at T1 and T2. We calculated the change in the amount of hard and soft tissues from T1 to T2 and determined the correlation between preoperative facial alveolar bone morphology and postoperative gingival recession.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>13 women and 7 men were recruited. A total of 20 implants were evaluated. The implant survival rate was 100%. The mean facial alveolar bone dehiscence width was 3.9\u2009\u00b1\u20091.6\u2009mm, and the mean depth from platform level was 2.9\u2009\u00b1\u20091.7\u2009mm. The mean implant body exposure on the buccal was 4.8\u2009\u00b1\u20091.7\u2009mm, and the mean socket width gap was 2.1\u2009\u00b1\u20090.8\u2009mm. At T1, the mean facial hard tissue width was 2.1\u2009\u00b1\u20090.7\u2009mm, and the mean height was 2.0\u2009\u00b1\u20090.7\u2009mm. The mean change in vertical gingival recession from T1 to T2 was 0.5\u2009\u00b1\u20090.5\u2009mm.
