The influence of zirconia customized transgingival structure on the soft and hard tissues around implants in patients with thin gingival biotype in the anterior tooth area
Objective To explore and analysis the influence of zirconia customized transgingival structure on the soft and hard tissues around implants in patients with thin gingival biotype in the anterior tooth area.Methods A total of 85 patients with single dental implant restoration in the anterior dental area from May 2019 to August 2023 were selected and divided into 43 in the zirconia group and 42 in the metal group.All patients were treated with implant repair,the metal group was assisted with cobalt-chromium alloy porcelain crown,and the zirconia group used personalized zirconia gingival structure to record the changes of soft and hard tissues around the implant.Results All patients'implants were successfully preserved,the plaque index(PLI)was significantly lower in the zirconia group and the metal group than 1d before repair,the periodontal probing depth(PD)was significantly higher than 1d before repair(P＜0.05),and the PLI and PD of 1 year after repair in the zirconia group were also different compared with the metal group(P＜0.05).The amount of bone resorption at the implant margin after 3 months,6 months and 1 year in the zirconia group was significantly less than that in the metal group(P＜0.05).The pink aesthetic score(PES)and white aesthetic score(WES)were significantly higher in the zirconia group than in the metal group(P＜0.05).The incidence of complications such as gingivitis,implant loosening,gingival perforation,and fistula formation was 2.33％in the zirconia group,19.05％in the metal group,and significantly lower in the zirconia group compared with the metal group(P＜0.05).Conclusions The application of zirconia customized transgingival structure in patients with thin gingival biotype can improve the condition of soft and hard tissues around implants in the anterior tooth area,increase the amount of marginal bone resorption around the implants,enhance the aesthetic condition of implants in the anterior tooth area,and also reduce the incidence of complications.
