Abstract
Objective To investigate the therapeutic effect and aesthetic effect of tent bone augmentation technique on single upper anterior tooth loss and its influence on the width of alveolar bone.Methods 80 patients with single upper anterior tooth loss who were treated in Hanbin District Third People's Hospital from February 2020 to February 2021 were selected and divided into study group(tent bone augmentation technique,38 cases)and control group(guided bone regeneration,42 cases)according to different treatment methods.The implantation status,pink and white esthetic scores,alveolar bone width,gingival crevicular fluid bone metabolism indicators,periodontal status and incidence rates of postoperative complications were compared between the two groups.Results After 3 months of implant placement,there was no implant loosening or falling off in both groups of patients.There was no transparent area in imaging examination,and the implantation success rate was 100%.At 6 months after surgery,the PES score around implantation area of study group was higher than that of control group(P＜0.05),but there was no statistical significance in the WES score between the two groups(P＞0.05).The alveolar bone width at 6 months after surgery was significantly widen in both groups(P＜0.05),and the alveolar bone width of study group was wider than that of control group at 6 months after surgery(P＜0.05).The OPG level in the gingival crevicular fluid of the two groups at 6 months after surgery was significantly decreased while the OPN level was significantly increased(P＜0.05),and the OPG in study group was higher than that in control group(P＜0.05)while the OPN level was lower than that in control group(P＜0.05).There were no statistical differences in the gingival index,plaque index and probing depth between the two groups at 6 months after surgery(P＞0.05).There was no significant difference in the incidence of postoperative complications between the two groups(P＞0.05).Conclusion Tent bone augmentation technique applied to single upper anterior tooth loss has a high success rate of implantation,and can enhance the aesthetic effect after restoration,increase the width of alveolar bone,and slow down the bone resorption,and it has small influence on postoperative complications and periodontal status.关键词
