Inclusion criteria
Inclusion criteria: The study population included patients who had received complete periodontal basic treatment, single tooth loss in molar area, sufficient bone mass, and were ready to complete implant restoration treatment in the Department of Stomatology and periodontology of Peking University. This study is a non randomized controlled study. According to the preoperative CBCT and the digital synthetic image of the research model, the thickness of the crest soft tissue of the implant site was measured to determine whether it met the inclusion criteria and grouping. Inclusion criteria of the experimental group: the thickness of soft tissue in the planting area <= 2mm; Inclusion criteria of the control group: the thickness of soft tissue in the area to be planted was 2-3mm.
