[Abstract]:Objective to observe and analyze the aesthetic effect of soft tissue implant and bone tissue implant in patients with maxillary single anterior tooth loss, and to use the red aesthetic index (Pink Esthetic Score,). PES) to evaluate the application range, success rate, aesthetic effect and other related factors of two kinds of implants in maxillary anterior teeth. Methods from January 2011 to July 2013, the data of 85 patients with single tooth loss in maxillary anterior teeth who were treated with implant therapy in Department of Stomatology, Zhengzhou University were retrospectively analyzed. A total of 85 implants were implanted, including 41 cases in the soft tissue level implant group, 22 males and 19 females, aged 39.1 鹵2.2 years, and 41 ITI implants were implanted. Bone tissue level implant group (44 cases, male 28, female 16, age 36.8 鹵1.8 years) was implanted with 44 Ankylos implants. Three to six months after the restoration, the patients in the two groups were followed up. The intraoral positive photographs of the two groups were observed, and the aesthetic evaluation of the soft tissue around the implants was carried out with PES index, and the changes of each group were analyzed. Results the PES index was used to evaluate the soft tissue around implants. The index of soft tissue level increased from 7.24 鹵2.23 to 9.62 鹵2.06 at the time of wearing teeth (baseline period), and the difference was statistically significant. There were 2 cases of periimplant mucositis, no periimplant inflammation. The index of bone tissue level increased from 7.68 鹵2.19 in the baseline period to 10.14 鹵2.01in the follow-up period. The difference was statistically significant. There were 3 cases of periimplant mucositis and 1 case of peri-implant inflammation. There was no significant difference in PES index and PES summation between baseline and follow-up period. The retention rate of implants in both groups was 100. Conclusion the aesthetic effects of soft tissue implant and bone tissue implant were significantly improved within half a year after the restoration. The clinical observation showed that the aesthetic effect of the soft tissue around the single dental implant in the maxillary anterior dental region was significantly improved. Both of them could obtain satisfactory clinical effect in anterior teeth. For anterior dental implants, bone tissue level implants seem to have better aesthetic effects than soft tissue implants. The aesthetic effect of soft tissue around implants is affected by many factors. In order to achieve better aesthetic effect, it is necessary to strictly select indications, formulate reasonable surgical procedures and repair methods.
