In 23 patients (study group), grafts were covered with autogenous pericranium before suturing, while in 21 patients (control group) no coverage of the grafts before suturing was performed. After a 4\u20137\u00a0month waiting period, 199 implants were placed (105 in the study group, 94 in the control group) and 3\u20134\u00a0months afterward prosthetic rehabilitation was carried out. The mean follow\u2010up after the start of prosthetic loading was 23.9\u00a0months (range: 12\u201348\u00a0months).<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>The incidence of soft tissue dehiscences was 5,7% in the study group and 16% in the control group. The mean graft resorption before implant placement was 0.12\u00a0mm (SD\u00a0\u00b1\u00a00.32) in the study group and 0.98\u00a0mm (SD\u00a0\u00b1\u00a02.79) in the control group. The mean peri\u2010implant bone resorption at the end of the follow\u2010up period was 0.21\u00a0mm (SD\u00a0\u00b1\u00a00.48) in the study group and 0.43\u00a0mm (SD\u00a0\u00b1\u00a00.83) in the control group.
