Clinical analysis of screw tenting technology in implant restoration of multiple missing teeth in the anterior esthetic zone
摘要
Abstract
Objective To use a retrospective clinical approach to analyze the clinical treatment effects of screw tenting technology in implant restoration of consecutively missing teeth in the anterior esthetic zone.Methods A total of 86 patients with consecutive anterior teeth esthetic area defects who were treated at the Implant Center of the West City Branch of Hangzhou Stomatology Hospital from December 2019 to December 2023 were included.They were divided into the experimental group(tenting screw technique+delayed implantation)and the control group(conventional guided bone regeneration technique+immediate implantation),with 43 cases in each group.Cone beam computed tomography(CBCT)imaging data of patients were collected at the following time points:before bone augmentation,6 months,and 12 months after bone augmentation,after implant placement,and 1 to 12 months after final restoration.The implant survival rate of the two groups was compared.Based on CBCT digital imaging data,the alveolar bone width at the alveolar ridge crest of the two groups of patients 6 months and 12 months after bone augmentation was measured respectively.Meanwhile,the esthetic status of the implant restorations immediately after restoration,6 months after restoration,and 12 months after restoration was evaluated using the pink esthetic score,and the differences between the two groups were compared.Results The implant survival rate was 98.21%in the control group and 100.00%in the experimental group.The alveolar bone width at the alveolar ridge crest in the experimental group was higher than that in the control group at 6 months and 12 months after bone augmentation,with values of(7.69±0.42)mm and(7.22±0.40)mm in the experimental group,and(6.53±0.39)mm and(6.20±0.43)mm in the control group(P=0.001).The pink esthetic score(PES)of the experimental group was higher than that of the control group at 6 months and 12 months after the final restoration,with scores of(10.72±1.42)and(9.95±1.34)in the experimental group,and(7.52±1.20)and(7.01±1.15)in the control group(P=0.001).Conclusion The tenting screw technique can effectively ensure the survival rate of implants in the implant restoration of consecutive anterior teeth esthetic area defects.Its implantation effect is comparable to that of the guided bone regeneration(GBR)technique.In the implant restoration cases of consecutive anterior teeth esthetic area defects,the tenting screw technique can achieve better bone augmentation and restoration effects.关键词
