目的对单颗上前牙早期种植后周围软组织美学效果进行观察和分析。方法筛选2010年2月至2012年4月在郑州人民医院口腔科就诊的行单颗上颌中切牙早期种植患者30例,记录并分析种植体初戴时以及戴入3、12、24个月时种植体留存率、红色美学指数(PES)、改良龈沟出血指数(MBI)、牙周探诊深度(PD)和患者满意度。采用Spss15.0软件包进行数据分析。结果 30枚种植体存留率为100%,至24个月随访时骨吸收为(0.61±0.16)mm,PES值从基线期(6.33±1.42)分增加至24个月的(10.83±2.10)分,MBI为0.98±0.68,PD为(2.16±0.27)mm,各时间点MBI及PD均值比较差异均无统计学意义(均P>0.05),患者非常满意率为86.6%。结论单颗上颌前牙缺失采用早期种植,可获得较好的软组织美学效果和患者满意度。
Objective To observe and analyze the aesthetic effect of soft tissue around the anterior teeth after single planting. Methods Thirty patients with early single maxillary central incisor who were treated in Department of Stomatology, Zhengzhou People’s Hospital from February 2010 to April 2012 were screened and 30 patients were enrolled in this study. Time implant retention, red aesthetic index (PES), modified gingival sulcus bleeding index (MBI), periodontal exploration depth (PD), and patient satisfaction. Spss15.0 software package for data analysis. Results The survival rate of 30 implants was 100%. The bone resorption was (0.61 ± 0.16) mm at 24 months of follow - up. The PES value increased from 6.33 ± 1.42 to 10.83 ± 2.10 at 24 months , MBI was 0.98 ± 0.68, and PD was (2.16 ± 0.27) mm. There was no significant difference in mean MBI and PD at all time points (all P> 0.05). The rate of satisfaction was 86.6%. Conclusion Single maxillary anterior teeth loss using early planting, get better soft tissue aesthetic effect and patient satisfaction.
