摘　　要：目的通过红/白美学评分分析上颌单颗中切牙拔牙位点保存后种植治疗的美学效果。方法选择2006年3月至2014年12月上颌单颗中切牙行拔牙位点保存后延期种植并完成最终修复的9例病例,共植入9颗种植体。随访期均在4年以上,平均为7.7年。治疗过程为拔除上颌单颗中切牙后,向拔牙窝内植入骨代用品,3~6个月植入种植体,愈合3~4个月后完成最终修复。评价方法为临床检查和数码照片,进行红色美学评分(PES)和白色美学评分(WES)评估。结果9例种植体全部实现骨结合。PES/WES总分平均分为(16.56±1.34)(范围15~19)。PES总分平均分(7.78±1.13)(范围6~9),近中龈乳头高度平均分最高,为(1.89±0.31),而唇侧根面突度/软组织颜色及质地平均分最低,为(1.11±0.57),远中龈乳头高度和唇侧黏膜高度平均分为(1.56±0.50);WES总平均分为(8.78±0.63)(范围8~10)。结论拔牙位点保存是避免拔牙窝愈合过程中唇侧骨板吸收的可靠手段之一。基于PES/WES显示的结果,上颌单颗中切牙拔牙位点保存后种植治疗可以获得满意的美学效果。Objective The aim of this study was to evaluate the esthetic outcome of single maxillary incisor after delayed implant placement with alveolar ridge preservation,with index of pink and white esthetic scores.Methods Atotal of 9 cases treated from March 2006 to December 2014 were included in this study,each of which had one central maxillary incisor extracted followed by alveolar ridge preservation.The mean follow-up was 7.7 year,and all the data was gathered retrospectively over 4 years.The implants were placed after a healing period of 3~6 months,and the crowns were inserted 3~4 months after surgery.The assessment was performed using digital photographs presenting corresponding clinical situation with Pink Esthetic score(PES)and White esthetic score(WES).Results All the 9 implants were osseointegrated.The mean total PES/WES was(16.56±1.34)(range:15 to 19).The mean PES was(7.78±1.13)(range:6 to 9),the mesial papilla had the highest mean score(1.89±0.31),but root convexity/soft tissue color and texture had the lowest mean score(1.11±0.57),mean scores for the facial mucosa curvature and the distal papilla were the same as 1.56±0.50.mean scores for WES was(8.78±0.63)(range:8 to 10).Conclusion Delayed implant placement with alveolar ridge preservation is an effective technique in achieving satisfactory esthetic Results of maxillary incisor.
