在行全口义齿修复时,前牙选择的方法很多。早在1914年Williams提出了著名的几何学说,1957年Frush和Fisher提出SPA学说。许多人对此作了研究,结论多为牙型、面型、年龄、性别间没有明显的关系。有人进行测量研究,报告上中切牙宽度为两侧颧骨之间距离的1/16,其高度为发际点到息止位颏下点距离的1/16,有人认为口角与尖牙远中面相对,可用口角线确定前牙宽度。1962年Lee提出用“前额宽度:唇水平的面部宽度:颧点间宽度=上中切牙龈1/3处宽度:切角处宽度:牙最大宽度”公
In the line of complete denture repair, the choice of anterior many ways. As early as 1914, Williams proposed the famous theory of geometry. In 1957, Frush and Fisher proposed SPA theory. Many people have done research, the conclusions are mostly tooth type, face type, age, gender, there is no obvious relationship. Someone to carry out measurement studies, the report on the width of the incisors on both sides of the distance between the cheekbones 1/16, the height of the hair to the point of interest to stop the submental distance 1/16, some people think that mouth and canine far Face relative, the available mouth line to determine the width of the anterior teeth. 1962 Lee proposed using “forehead width: lip horizontal facial width: width between the zygomatic point = 1/3 on the incision in the gingival width: width at the corner: the maximum width of the teeth” male
