Abstract: Objective：To observe the curative effect of dental implant restoration in the treatment of dentition defect. Methods：The clinical medical records of 100 patients with dentition defect who were treated in our hospital during January 2019 to January 2020 were selected as the research objects， and the retrospective study method was used. According to the treatment methods， the patients were divided into the observation group (n=50) and the control group (n=50). The patients in the control group were treated with conventional fixed bridge repair therapy， while the patients in the observation group were treated with oral implant repair therapy. Inflammatory factors in gingival crevicular fluid， plaque index， gingival crevicular bleeding index， gingival index， and satisfaction-related index scores were counted after 1 month of treatment. The therapeutic effect,complications and patient satisfaction of the two groups were analyzed after 6 months of treatment. The oral health-related quality of life scores of the two groups of patients were measured， and the above data were collected for comparison after 30 months of treatment. Results：The treatment effective rate in the observation group was 98.00%， which was higher than that of the control group(75.00%) (P<0.05). The total incidence rate of complications in the observation group was 12.00%， which was lower than that of the control group (28.00%)(P<0.05). Before treatment， the inflammatory factors， plaque index， gingival crevicular bleeding index， gingival index， satisfaction-related index scores， and oral health-related quality of life scores in the two groups of patients were not statistically significant (P>0.05). At different times after treatment， the scores of inflammatory factors and satisfaction-related indexes in gingival crevicular fluid were higher than those before treatment (P<0.05)， while the scores of plaque index， gingival crevicular bleeding index， gingival index and oral health-related quality of life were lower than those before treatment(P<0.05)， and the values of each index in the observation group were better than those in the control group (P<0.05). Conclusion： Compared with the conventional fixed bridge repair therapy， the oral implant repair therapy can improve the treatment efficacy and aesthetics， reduce the incidence of complications. The patient satisfaction is high， and the clinical effect is good.
