摘　　要：目的分析影响上颌中切牙单个种植修复体龈乳头高度的因素,探讨促进种植修复美学效果的相关因素。方法选择16例上颌中切牙单个种植修复患者(30个龈乳头),通过分析临床资料、口内照片、X 线片和研究模型,得到龈乳头高度及相关因素数据,采用多重线性回归方法进行分析。结果 16例患者中切牙种植修复体龈乳头高度为(4.01±1.85)mm,影响龈乳头高度的相关因素按作用由大到小的排列顺序为:种植修复体外冠接触点高度、邻近天然牙邻面牙槽嵴顶高度、邻近天然牙邻面牙槽嵴顶到外冠接触点的垂直距离、种植修复体外冠邻面凸度、种植体基台与邻牙牙根距离、冠根长度比例、种植修复体邻面牙槽嵴顶高度、种植修复体外冠唇面凸度、探诊深度。结论中切牙种植修复体龈乳头高度受多种因素影响。Objective To analyze and find factors affecting the height of adjacent glngival papilla of maxillary central incisor single implant in human in order to promote the esthetic result of dental implants. Methods Sixteen maxillary central incisor single implants of 16 patients and 30 sites of adjacent tissues and prosthesis were evaluated. Data on the height of adjacent gingival papilla of dental implant and relative factors were obtained from clinical parameters, photographs, research models, and X radiographs. Results The mean and standard deviation of adjacent gingival papilla height of maxillary central incisor single implant were （4. 01 ±1.85 ） mrn. Statistical analysis revealed that factors affecting the height of adjacent ginglval papilla of implant were as following from strong to weak ： vertical distance between contact point and ginglval margin, vertical distance between proximal bone level of natural tooth and implant abutment, vertical distance between proximal bone level of natural tooth and contact point, proximal protruding degree of crown, horizontal distance between abutment and root, length ratio of the crown and fixture, vertical distance between proximal bone level of implant and abutment, lip-side protruding degree of crown, probing depth. Conclusions Multiple factors affected the height of adjacent gingival papilla of maxillary central incisor single implant in human.
