Abstract
Objective To explore the influence of thin gingival and thick gingival biotype on the aesthetic effect after implantation underwent guided bone regeneration(GBR)in the aesthetic zone.Methods Total of 116 patients who underwent implant restoration and underwent GBR during the same period in the hospital from February 2018 to December 2021 were selected.According to different gingival biotype,the patients were divided into group A(n=57,thin gingival biotype)and group B(n=59,thick gingival biotype).Implant restoration was performed on all patients and GBR was performed at the same time.The implant effect,papilla fill index(PFI),pink esthetic score(PES),white esthetic score(WES)and satisfaction of the two groups were observed.Results The planting success rate of both groups was 100%.The degree of gingival margin recession in group B was less than group A(P＜0.05).The number of PFI scores in group B with 0 and 1 degree was less than in group A,and the number of 3 degree was more than in group A(P＜0.05).The texture,color,distal gingival papilla,mesial gingival papilla and total PES score of group B were higher than group A(P＜0.05).The crown shape,crown volume and shape and total WES score of group B were higher than group A(P＜0.05).The total satisfaction of group B was better than group A(P＜0.05).Conclusion For patients who underwent GBR during aesthetic zone repair,the thick gingival biotype has a better aesthetic effect than the thin gingiva,and it can prevent gingival margin regression,and the patient's satisfaction is higher.关键词
