Abstract:
Objective To compare the effect of immediate implantation and delayed implantation on the surrounding tissue.Methods The clinical data of 98 cases of anterior teeth with single implant repair were analyzed retrospectively,and they were divided into study group (n =50) and control group (n =48) according to the method of implantation.The patients in the study group were implanted in the tooth socket immediately after the minimally invasive tooth extraction,and the patients in the control group were implanted after 12-16 weeks of minimally invasive extraction.All the two groups were repaired in coronal at 6 months after implantation.The success rate of implant,implant bone resorption,periodontal probing depth,gingival bleeding index,plaque index and red aesthetic score were compared between the two groups.Results The success rate was 100％ in the two groups after 12 months,the difference was not statistically significant(P ＞ 0.05).The implant surrounding bone absorption in the study group was lower than that in the control group,the differences were statistically significant (t =2.132,2.241,2.421,all P ＜ 0.05).At the end of 3 and 6 months,the depth of probing in the study group were significantly lower than those in the control group (t =2.019,2.307,all P ＜ 0.05),and the red aesthetic score in the study group was significantly higher than that in the control group,the differences were statistically significant [(7.97 ± 1.12) points vs.(6.82 ± 1.03) points,(8.65 ± 1.14) points vs.(7.42 ± 1.07) points,t =2.012,2.137,all P ＜ 0.05].The modified sulcus bleeding index and plaque index had no statistically significant differences between the two groups (all P ＞ 0.05).Conclusion The clinical effect of immediate implant restoration of anterior teeth is better than delayed implantation.
