【摘要】：目的对上颌单个前牙缺失患者，采用软组织水平种植体与骨组织水平种植体修复后的软组织美学效果进行观察和分析，用红色美学指数（Pink Esthetic Score，PES)评价两类种植体在上颌前牙区的应用范围、成功率、美学效果及其他相关因素。方法对2011年1月至2013年7月在郑州大学口腔医院种植科接受种植治疗的85例上颌前牙区单牙缺失患者病例资料进行回顾分析。共植入种植体85颗，其中软组织水平种植体组41例，男22例，女19例，年龄39.1±2.2岁，植入41颗ITI种植体；骨组织水平种植体组44例，男28例，女16例，年龄36.8±1.8岁，植入44颗Ankylos种植体。修复后3-6个月随访，观察两组病例在戴牙时及随访时的口内正面照片，用PES指数对种植体周围软组织进行美学评价，分析各自变化情况。结果使用PES指数评价种植体周围软组织，软组织水平组指数由戴牙时（基线期）的7.24±2.23上升到随访时（随访期）的9.62±2.06，差异有统计学意义，种植体周围黏膜炎2例，无种植体周围炎。骨组织水平组指数由基线期的7.68±2.19上升到随访期的10.14±2.01，差异有统计学意义，种植体周围黏膜炎3例，种植体周围炎1例。基线期和随访期两组的PES各单项指数、PES总和的差异均无统计学意义，两组种植体留存率均为100%。结论软组织水平种植体与骨组织水平种植体在修复体戴入后的半年内，上颌前牙区单牙种植体周围软组织的美学效果均有明显改善，临床观察结果显示，二者在前牙区均可获得满意的临床疗效。对于前牙区种植修复，骨组织水平种植体似乎比软组织水平种植体更易获得良好的美学效果。种植体周围软组织的美学效果受多因素影响，，为了达到较好的美学效果，应该严格选择适应证、制定合理的外科手术方案及修复方式。
[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 卤2.2 years, and 41 ITI implants were implanted. Bone tissue level implant group (44 cases, male 28, female 16, age 36.8 卤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 卤2.23 to 9.62 卤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 卤2.19 in the baseline period to 10.14 卤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.
