Abstract: Objective: To analyze the effects of immediate planting and early planting on the soft tissues around the implants in the edentulous aesthetic area. Methods: A total of 60 patients with single anterior teeth loss from August 2015 to August 2019 were randomly selected. Among them, 30 patients were implanted immediately after tooth extraction(observation group), and 30 patients were implanted early after tooth extraction. Into the control group, the zirconia all-ceramic restoration was given to the Astra Tech implants and implants six months later, and the results were reviewed after half a year. The red aesthetic scores(PES) of the two groups were compared. Results: There was no significant difference between the two groups in the PES score and the PES scores of each node(P>0.05). In the PES scores of each node, the gingival biotype and alveolar bone defect, the distal nipple, the missing tooth position and the gingival height and there is a significant correlation between the cause of missing teeth and the height of near and far. Conclusion: The effects of immediate implantation and early implantation on the soft tissue around the implant in the edentulous aesthetic area are not obvious. The main effects of soft tissue aesthetics on implant restoration in the anterior aesthetic area include missing tooth position, gingival biotype and lack of teeth.
