【摘要】：目的:在上颌前牙区单个缺失牙患者种植义齿修复中,采用不同软组织处理方式对种植义齿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 Esth etic Score,PES)评价三种软组织处理方式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:选择2011年9月至2013年6月在青岛大学附属医院口腔种植中心进行种植义齿修复的30例患者作为研究对象进行回顾性分析。随机分为三组,A组为唇侧黏骨膜瓣滑行组,B组为腭黏膜下结缔组织瓣移植组,C组为唇侧ADM骨膜下植入组,种植义齿负载半年后按一定标准拍摄口内照片,两位观察者用红色美学指数(pink esthetic score,PES)评估口内照片中种植体周软组织各项得分。分组进行统计学分析,分析不同软组织处理与PES值之间的关系。结果:种植义齿负载半年后三组种植体留存率均为100%;A组PES平均9.57(±2.10)分,B组PES平均为10.77(±2.56)分,C组PES平均为10.14(±2.32)分,B组及C组种植义齿修复后PES值较A组PES值高(P0.05)。B组与C组之间P ES值无显著性差异(P0.05)结论:在上颌前牙美学区进行单牙种植修复时,采取异种脱细胞真皮基质骨膜下植入及腭黏膜下结缔组织瓣移植,可以改善种植区唇侧的美学效果。
[Abstract]:Objective: to observe and analyze the aesthetic effect of implant denture in patients with single missing teeth in maxillary anterior region by using different soft tissue treatments. The application range, success rate, aesthetic effect and other related factors of three soft tissue management methods in maxillary anterior teeth were evaluated by red aesthetic index (Pink Esth etic Score,PES). Methods: from September 2011 to June 2013, 30 patients who were treated with implant prosthesis in the oral implant center of affiliated hospital of Qingdao University were retrospectively analyzed. Three groups were randomly divided into three groups: group A, group B: subpalatal connective tissue flap transplantation, group C, subperiosteal implantation of labial ADM, intraoral photographs were taken according to certain standards after implant denture was loaded for half a year. The two observers used the red aesthetic index (pink esthetic score,PES) to assess the scores of periimplant soft tissue in intraoral photographs. Statistical analysis was carried out to analyze the relationship between different soft tissue processing and PES value. Results: the retention rate of implants was 9.57 (卤2.10) in group A, 10.77 (卤2.56) in PES of group B and 10.14 (卤2.32) in group C after implant denture loading. The PES value of group B and group C was higher than that of group A (P0.05). There was no significant difference in P ES between the two groups (P0.05) conclusion: in the aesthetic area of maxillary anterior teeth, there was no significant difference between the two groups. Xenogeneic acellular dermal matrix subperiosteal implantation and palatine submucosal connective tissue flap transplantation can improve the aesthetic effect of labial side.
