Effect of Immediate Implantation Timing on the Amount of Alveolar Bone Absorption and Aesthetic Effect in Patients with Maxillary Single Anterior Tooth Loss
Objective To investigate the effect of immediate implant timing on alveolar bone resorption and aesthetic effects in patients with maxillary single anterior tooth loss.Methods A total of 84 patients with missing maxillary single anterior teeth who underwent pre-implant denture restoration in the Department of Prosthodontics of the author's hospital from October 2019 to October 2021 were selected and divided into control group(n=42)and observation group(n=42).The control group was treated with delayed implantation and immediate repair,and the observation group was treated with immediate implantation and immediate repair.The clinical efficacy of the two groups was compared.The red aesthetic index(PES)and the white aesthetic index(WES)were used to evaluate the soft tissue aesthetic effect of the two groups,and the bone resorption-related indicators,complications and patient satisfaction were compared between the two groups.Results The effective rate of treatment in the observation group was higher than that in the control group(P＜0.05).Three months after repair,the PES and WES scores of the observation group were higher than those of the control group,and the alveolar bone resorption value of the observation group was lower than that of the control group(P＜0.05).6 months after repair,the PES and WES scores of the two groups were decreased,and the alveolar bone resorption values were increased,and the PES and WES scores of the observation group were higher than those of the control group,and the alveolar bone resorption values were lower than those of the control group(P＜0.05).There was no significant difference in the width of alveolar ridge,the thickness of the labial bone plate and the total complication rate between the two groups(P＞0.05).After 6 months of repair,the overall appearance,attachment height and masticatory function scores of the observation group were higher than those of the control group(P＜0.05).There was no significant difference in implant color between the two groups(P＞0.05).Conclusion Immediate implant restoration in patients with missing maxillary anterior teeth has a significant effect,which can effectively restore the aesthetic effect of the patients'gingival soft tissue,with low bone resorption and high patient satisfaction.
