摘要 目的:通过分析单枚后牙种植修复体龈乳头形态及变化,探讨其与种植修复体牙龈美学有关的相关因素。方法:选择20枚后牙种植修复体,通过修复后不同时期的临床检查、根尖片、研究模型、患者满意度调查等方法,得到种植修复体龈乳头高度、牙龈乳头指数(papilla index score,PIS)和患者满意度数据,并进行统计分析。结果:随访到的19枚种植体均形成良好的骨结合,所观察的35个龈乳头中,根据Jemt的PIS分级,11个龈乳头为Ⅲ级,19个龈乳头为Ⅱ级,5个龈乳头为Ⅰ级。龈乳头高度在修复完成后即刻、修复后1个月、修复后3个月的3次测量中逐次增大。使用SAS 9.13软件进行统计分析,其差异有高度统计学意义(P<0.01)。在患者满意度问卷调查中,满意率达89.47%。结论:单枚后牙种植修复体的龈乳头高度在冠修复完成后的3个月内随时间延长而增高。 Objective: To observe the gingival papillae contour and its variation after posterior single-tooth implant-supported restoration.Methods: 20 single-tooth implant-supported restorations which were followed-up for more than 3 months were retrospectively evaluated.Data related with the height of gingival papillae,the papilla index score(PIS),and questionnaire of the patient's satisfaction were obtained.Analysis of data were performed with SAS 9.13 software.P0.01 was considered high significant.Results: 19 implants showed osseointegration.In the 35 observed gingival papillae,the mesial and distal papillae index score was at levels 3 in 11,at levels 2 in 19,at levels 1 in 5.Questionnaire of the patient's satisfaction degree was 89.47%.The heights of gingival papillae measured immediately after restoration,at the end of 1-month and 3-month respectively revealed significant differences(P0.01).Conclusion: The heights of gingival papillae supported by a single implant restoration grows to the top at the end of three months when final crown prostheses were done.
